Page

Page provides methods to interact with a single tab in a Browser, or an extension background page in Chromium. One Browser instance might have multiple Page instances.

This example creates a page, navigates it to a URL, and then saves a screenshot:

import com.microsoft.playwright.*;

public class Example {
  public static void main(String[] args) {
    try (Playwright playwright = Playwright.create()) {
      BrowserType webkit = playwright.webkit();
      Browser browser = webkit.launch();
      BrowserContext context = browser.newContext();
      Page page = context.newPage();
      page.navigate("https://example.com");
      page.screenshot(new Page.ScreenshotOptions().setPath(Paths.get("screenshot.png")));
      browser.close();
    }
  }
}

The Page class emits various events (described below) which can be handled using any of Node's native EventEmitter methods, such as on, once or removeListener.

This example logs a message for a single page load event:

page.onLoad(p -> System.out.println("Page loaded!"));

To unsubscribe from events use the removeListener method:

Consumer<Request> logRequest = interceptedRequest -> {
  System.out.println("A request was made: " + interceptedRequest.url());
};
page.onRequest(logRequest);
// Sometime later...
page.offRequest(logRequest);

方法 (Methods)​

addInitScript​

Added before v1.9 page.addInitScript

Adds a script which would be evaluated in one of the following scenarios:

  • Whenever the page is navigated.
  • Whenever the child frame is attached or navigated. In this case, the script is evaluated in the context of the newly attached frame.

The script is evaluated after the document was created but before any of its scripts were run. This is useful to amend the JavaScript environment, e.g. to seed Math.random.

使用方式

An example of overriding Math.random before the page loads:

// preload.js
Math.random = () => 42;
// In your playwright script, assuming the preload.js file is in same directory
page.addInitScript(Paths.get("./preload.js"));
note

The order of evaluation of multiple scripts installed via BrowserContext.addInitScript() and Page.addInitScript() is not defined.

參數

  • script String | Path#

    Script to be evaluated in all pages in the browser context.

addLocatorHandler​

Added in: v1.42 page.addLocatorHandler

When testing a web page, sometimes unexpected overlays like a "Sign up" dialog appear and block actions you want to automate, e.g. clicking a button. These overlays don't always show up in the same way or at the same time, making them tricky to handle in automated tests.

This method lets you set up a special function, called a handler, that activates when it detects that overlay is visible. The handler's job is to remove the overlay, allowing your test to continue as if the overlay wasn't there.

Things to keep in mind:

  • When an overlay is shown predictably, we recommend explicitly waiting for it in your test and dismissing it as a part of your normal test flow, instead of using Page.addLocatorHandler().
  • Playwright checks for the overlay every time before executing or retrying an action that requires an actionability check, or before performing an auto-waiting assertion check. When overlay is visible, Playwright calls the handler first, and then proceeds with the action/assertion. Note that the handler is only called when you perform an action/assertion - if the overlay becomes visible but you don't perform any actions, the handler will not be triggered.
  • After executing the handler, Playwright will ensure that overlay that triggered the handler is not visible anymore. You can opt-out of this behavior with setNoWaitAfter.
  • The execution time of the handler counts towards the timeout of the action/assertion that executed the handler. If your handler takes too long, it might cause timeouts.
  • You can register multiple handlers. However, only a single handler will be running at a time. Make sure the actions within a handler don't depend on another handler.
warning

Running the handler will alter your page state mid-test. For example it will change the currently focused element and move the mouse. Make sure that actions that run after the handler are self-contained and do not rely on the focus and mouse state being unchanged.

For example, consider a test that calls Locator.focus() followed by Keyboard.press(). If your handler clicks a button between these two actions, the focused element most likely will be wrong, and key press will happen on the unexpected element. Use Locator.press() instead to avoid this problem.

Another example is a series of mouse actions, where Mouse.move() is followed by Mouse.down(). Again, when the handler runs between these two actions, the mouse position will be wrong during the mouse down. Prefer self-contained actions like Locator.click() that do not rely on the state being unchanged by a handler.

使用方式

An example that closes a "Sign up to the newsletter" dialog when it appears:

// Setup the handler.
page.addLocatorHandler(page.getByText("Sign up to the newsletter"), () -> {
  page.getByRole(AriaRole.BUTTON, new Page.GetByRoleOptions().setName("No thanks")).click();
});

// Write the test as usual.
page.navigate("https://example.com");
page.getByRole("button", Page.GetByRoleOptions().setName("Start here")).click();

An example that skips the "Confirm your security details" page when it is shown:

// Setup the handler.
page.addLocatorHandler(page.getByText("Confirm your security details"), () -> {
  page.getByRole(AriaRole.BUTTON, new Page.GetByRoleOptions().setName("Remind me later")).click();
});

// Write the test as usual.
page.navigate("https://example.com");
page.getByRole("button", Page.GetByRoleOptions().setName("Start here")).click();

An example with a custom callback on every actionability check. It uses a <body> locator that is always visible, so the handler is called before every actionability check. It is important to specify setNoWaitAfter, because the handler does not hide the <body> element.

// Setup the handler.
page.addLocatorHandler(page.locator("body"), () -> {
  page.evaluate("window.removeObstructionsForTestIfNeeded()");
}, new Page.AddLocatorHandlerOptions().setNoWaitAfter(true));

// Write the test as usual.
page.navigate("https://example.com");
page.getByRole("button", Page.GetByRoleOptions().setName("Start here")).click();

Handler takes the original locator as an argument. You can also automatically remove the handler after a number of invocations by setting setTimes:

page.addLocatorHandler(page.getByLabel("Close"), locator -> {
  locator.click();
}, new Page.AddLocatorHandlerOptions().setTimes(1));

參數

  • locator Locator#

    Locator that triggers the handler.

  • handler Consumer<Locator>#

    Function that should be run once locator appears. This function should get rid of the element that blocks actions like click.

  • options Page.AddLocatorHandlerOptions (optional)

    • setNoWaitAfter boolean (optional) Added in: v1.44#

      By default, after calling the handler Playwright will wait until the overlay becomes hidden, and only then Playwright will continue with the action/assertion that triggered the handler. This option allows to opt-out of this behavior, so that overlay can stay visible after the handler has run.

    • setTimes int (optional) Added in: v1.44#

      Specifies the maximum number of times this handler should be called. Unlimited by default.

evaluate​

Added before v1.9 page.evaluate

Returns the value of the expression invocation.

If the function passed to the Page.evaluate() returns a Promise, then Page.evaluate() would wait for the promise to resolve and return its value.

If the function passed to the Page.evaluate() returns a non-Serializable value, then Page.evaluate() resolves to undefined. Playwright also supports transferring some additional values that are not serializable by JSON: -0, NaN, Infinity, -Infinity.

使用方式

Passing argument to expression:

Object result = page.evaluate("([x, y]) => {\n" +
  "  return Promise.resolve(x * y);\n" +
  "}", Arrays.asList(7, 8));
System.out.println(result); // prints "56"

A string can also be passed in instead of a function:

System.out.println(page.evaluate("1 + 2")); // prints "3"

ElementHandle instances can be passed as an argument to the Page.evaluate():

ElementHandle bodyHandle = page.evaluate("document.body");
String html = (String) page.evaluate("([body, suffix]) => body.innerHTML + suffix", Arrays.asList(bodyHandle, "hello"));
bodyHandle.dispose();

參數

  • expression String#

    JavaScript expression to be evaluated in the browser context. If the expression evaluates to a function, the function is automatically invoked.

  • arg EvaluationArgument (optional)#

    Optional argument to pass to expression.

傳回值

evaluateHandle​

Added before v1.9 page.evaluateHandle

Returns the value of the expression invocation as a JSHandle.

The only difference between Page.evaluate() and Page.evaluateHandle() is that Page.evaluateHandle() returns JSHandle.

If the function passed to the Page.evaluateHandle() returns a Promise, then Page.evaluateHandle() would wait for the promise to resolve and return its value.

使用方式

// Handle for the window object.
JSHandle aWindowHandle = page.evaluateHandle("() => Promise.resolve(window)");

A string can also be passed in instead of a function:

JSHandle aHandle = page.evaluateHandle("document"); // Handle for the "document".

JSHandle instances can be passed as an argument to the Page.evaluateHandle():

JSHandle aHandle = page.evaluateHandle("() => document.body");
JSHandle resultHandle = page.evaluateHandle("([body, suffix]) => body.innerHTML + suffix", Arrays.asList(aHandle, "hello"));
System.out.println(resultHandle.jsonValue());
resultHandle.dispose();

參數

  • expression String#

    JavaScript expression to be evaluated in the browser context. If the expression evaluates to a function, the function is automatically invoked.

  • arg EvaluationArgument (optional)#

    Optional argument to pass to expression.

exposeBinding​

Added before v1.9 page.exposeBinding

The method adds a function called name on the window object of every frame in this page. When called, the function executes callback and returns a Promise which resolves to the return value of callback. If the callback returns a Promise, it will be awaited.

The first argument of the callback function contains information about the caller: { browserContext: BrowserContext, page: Page, frame: Frame }.

See BrowserContext.exposeBinding() for the context-wide version.

note

Functions installed via Page.exposeBinding() survive navigations.

Details

Role selector does not replace accessibility audits and conformance tests, but rather gives early feedback about the ARIA guidelines.

Many html elements have an implicitly defined role that is recognized by the role selector. You can find all the supported roles here. ARIA guidelines do not recommend duplicating implicit roles and attributes by setting role and/or aria-* attributes to default values.

page.getByTestId("directions").click();

參數

傳回值

Details

By default, the data-testid attribute is used as a test id. Use Selectors.setTestIdAttribute() to configure a different test id attribute if necessary.

getByText​

Added in: v1.27 page.getByText

Allows locating elements that contain given text.

See also Locator.filter() that allows to match by another criteria, like an accessible role, and then filter by the text content.

使用方式

Consider the following DOM structure:

<div>Hello <span>world</span></div>
<div>Hello</div>

You can locate by text substring, exact string, or a regular expression:

// Matches <span>
page.getByText("world");

// Matches first <div>
page.getByText("Hello world");

// Matches second <div>
page.getByText("Hello", new Page.GetByTextOptions().setExact(true));

// Matches both <div>s
page.getByText(Pattern.compile("Hello"));

// Matches second <div>
page.getByText(Pattern.compile("^hello$", Pattern.CASE_INSENSITIVE));

參數

  • text String | Pattern#

    Text to locate the element for.

  • options Page.GetByTextOptions (optional)

    • setExact boolean (optional)#

      Whether to find an exact match: case-sensitive and whole-string. Default to false. Ignored when locating by a regular expression. Note that exact match still trims whitespace.

傳回值

Details

Matching by text always normalizes whitespace, even with exact match. For example, it turns multiple spaces into one, turns line breaks into spaces and ignores leading and trailing whitespace.

Input elements of the type button and submit are matched by their value instead of the text content. For example, locating by text "Log in" matches <input type=button value="Log in">.

getByTitle​

Added in: v1.27 page.getByTitle

Allows locating elements by their title attribute.

使用方式

Consider the following DOM structure.

<span title='Issues count'>25 issues</span>

You can check the issues count after locating it by the title text:

assertThat(page.getByTitle("Issues count")).hasText("25 issues");

參數

  • text String | Pattern#

    Text to locate the element for.

  • options Page.GetByTitleOptions (optional)

    • setExact boolean (optional)#

      Whether to find an exact match: case-sensitive and whole-string. Default to false. Ignored when locating by a regular expression. Note that exact match still trims whitespace.

使用方式

Page.goBack();
Page.goBack(options);

參數

  • options Page.GoBackOptions (optional)

    • setTimeout double (optional)#

      Maximum operation time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the BrowserContext.setDefaultNavigationTimeout(), BrowserContext.setDefaultTimeout(), Page.setDefaultNavigationTimeout() or Page.setDefaultTimeout() methods.

    • setWaitUntil enum WaitUntilState { LOAD, DOMCONTENTLOADED, NETWORKIDLE, COMMIT } (optional)#

      When to consider operation succeeded, defaults to load. Events can be either:

isClosed​

Added before v1.9 page.isClosed

Indicates that the page has been closed.

使用方式

Page.isClosed();

傳回值

locator​

Added in: v1.14 page.locator

The method returns an element locator that can be used to perform actions on this page / frame. Locator is resolved to the element immediately before performing an action, so a series of actions on the same locator can in fact be performed on different DOM elements. That would happen if the DOM structure between those actions has changed.

Learn more about locators.

使用方式

Page.locator(selector);
Page.locator(selector, options);

參數

  • selector String#

    A selector to use when resolving DOM element.

  • options Page.LocatorOptions (optional)

    • setHas Locator (optional)#

      Narrows down the results of the method to those which contain elements matching this relative locator. For example, article that has text=Playwright matches <article><div>Playwright</div></article>.

      Inner locator must be relative to the outer locator and is queried starting with the outer locator match, not the document root. For example, you can find content that has div in <article><content><div>Playwright</div></content></article>. However, looking for content that has article div will fail, because the inner locator must be relative and should not use any elements outside the content.

      Note that outer and inner locators must belong to the same frame. Inner locator must not contain FrameLocators.

    • setHasNot Locator (optional) Added in: v1.33#

      Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the outer one. For example, article that does not have div matches <article><span>Playwright</span></article>.

      Note that outer and inner locators must belong to the same frame. Inner locator must not contain FrameLocators.

    • setHasNotText String | Pattern (optional) Added in: v1.33#

      Matches elements that do not contain specified text somewhere inside, possibly in a child or a descendant element. When passed a string, matching is case-insensitive and searches for a substring.

    • setHasText String | Pattern (optional)#

      Matches elements containing specified text somewhere inside, possibly in a child or a descendant element. When passed a string, matching is case-insensitive and searches for a substring. For example, "Playwright" matches <article><div>Playwright</div></article>.

傳回值

navigate​

Added before v1.9 page.navigate

Returns the main resource response. In case of multiple redirects, the navigation will resolve with the first non-redirect response.

The method will throw an error if:

  • there's an SSL error (e.g. in case of self-signed certificates).
  • target URL is invalid.
  • the setTimeout is exceeded during navigation.
  • the remote server does not respond or is unreachable.
  • the main resource failed to load.

The method will not throw an error when any valid HTTP status code is returned by the remote server, including 404 "Not Found" and 500 "Internal Server Error". The status code for such responses can be retrieved by calling Response.status().

note

The method either throws an error or returns a main resource response. The only exceptions are navigation to about:blank or navigation to the same URL with a different hash, which would succeed and return null.

note

Headless mode doesn't support navigation to a PDF document. See the upstream issue.

使用方式

Page.navigate(url);
Page.navigate(url, options);

參數

  • url String#

    URL to navigate page to. The url should include scheme, e.g. https://. When a setBaseURL via the context options was provided and the passed URL is a path, it gets merged via the new URL() constructor.

  • options Page.NavigateOptions (optional)

    • setReferer String (optional)#

      Referer header value. If provided it will take preference over the referer header value set by Page.setExtraHTTPHeaders().

    • setTimeout double (optional)#

      Maximum operation time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the BrowserContext.setDefaultNavigationTimeout(), BrowserContext.setDefaultTimeout(), Page.setDefaultNavigationTimeout() or Page.setDefaultTimeout() methods.

    • setWaitUntil enum WaitUntilState { LOAD, DOMCONTENTLOADED, NETWORKIDLE, COMMIT } (optional)#

      When to consider operation succeeded, defaults to load. Events can be either:

      • 'domcontentloaded' - consider operation to be finished when the DOMContentLoaded event is fired.
      • 'load' - consider operation to be finished when the load event is fired.
      • 'networkidle' - DISCOURAGED consider operation to be finished when there are no network connections for at least 500 ms. Don't use this method for testing, rely on web assertions to assess readiness instead.
      • 'commit' - consider operation to be finished when network response is received and the document started loading.

onceDialog​

Added in: v1.10 page.onceDialog

Adds one-off Dialog handler. The handler will be removed immediately after next Dialog is created.

page.onceDialog(dialog -> {
  dialog.accept("foo");
});

// prints 'foo'
System.out.println(page.evaluate("prompt('Enter string:')"));

// prints 'null' as the dialog will be auto-dismissed because there are no handlers.
System.out.println(page.evaluate("prompt('Enter string:')"));

This code above is equivalent to:

Consumer<Dialog> handler = new Consumer<Dialog>() {
  @Override
  public void accept(Dialog dialog) {
    dialog.accept("foo");
    page.offDialog(this);
  }
};
page.onDialog(handler);

// prints 'foo'
System.out.println(page.evaluate("prompt('Enter string:')"));

// prints 'null' as the dialog will be auto-dismissed because there are no handlers.
System.out.println(page.evaluate("prompt('Enter string:')"));

使用方式

Pauses script execution. Playwright will stop executing the script and wait for the user to either press the 'Resume' button in the page overlay or to call playwright.resume() in the DevTools console.

User can inspect selectors or perform manual steps while paused. Resume will continue running the original script from the place it was paused.

note

This method requires Playwright to be started in a headed mode, with a falsy setHeadless option.

使用方式

Page.pause();

pdf​

Added before v1.9 page.pdf

Returns the PDF buffer.

page.pdf() generates a pdf of the page with print css media. To generate a pdf with screen media, call Page.emulateMedia() before calling page.pdf():

note

By default, page.pdf() generates a pdf with modified colors for printing. Use the -webkit-print-color-adjust property to force rendering of exact colors.

使用方式

// Generates a PDF with "screen" media type.
page.emulateMedia(new Page.EmulateMediaOptions().setMedia(Media.SCREEN));
page.pdf(new Page.PdfOptions().setPath(Paths.get("page.pdf")));

The setWidth, setHeight, and setMargin options accept values labeled with units. Unlabeled values are treated as pixels.

A few examples:

  • page.pdf({width: 100}) - prints with width set to 100 pixels
  • page.pdf({width: '100px'}) - prints with width set to 100 pixels
  • page.pdf({width: '10cm'}) - prints with width set to 10 centimeters.

All possible units are:

  • px - pixel

requestGC​

Added in: v1.48 page.requestGC

Request the page to perform garbage collection. Note that there is no guarantee that all unreachable objects will be collected.

This is useful to help detect memory leaks. For example, if your page has a large object 'suspect' that might be leaked, you can check that it does not leak by using a WeakRef.

// 1. In your page, save a WeakRef for the "suspect".
page.evaluate("globalThis.suspectWeakRef = new WeakRef(suspect)");
// 2. Request garbage collection.
page.requestGC();
// 3. Check that weak ref does not deref to the original object.
assertTrue(page.evaluate("!globalThis.suspectWeakRef.deref()"));

使用方式

Page.requestGC();

route​

Added before v1.9 page.route

Routing provides the capability to modify network requests that are made by a page.

Once routing is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or aborted.

note

The handler will only be called for the first url if the response is a redirect.

note

Page.route() will not intercept requests intercepted by Service Worker. See this issue. We recommend disabling Service Workers when using request interception by setting setServiceWorkers to 'block'.

note

Page.route() will not intercept the first request of a popup page. Use BrowserContext.route() instead.

使用方式

An example of a naive handler that aborts all image requests:

Page page = browser.newPage();
page.route("**/*.{png,jpg,jpeg}", route -> route.abort());
page.navigate("https://example.com");
browser.close();

or the same snippet using a regex pattern instead:

Page page = browser.newPage();
page.route(Pattern.compile("(\\.png$)|(\\.jpg$)"),route -> route.abort());
page.navigate("https://example.com");
browser.close();

It is possible to examine the request to decide the route action. For example, mocking all requests that contain some post data, and leaving all other requests as is:

page.route("/api/**", route -> {
  if (route.request().postData().contains("my-string"))
    route.fulfill(new Route.FulfillOptions().setBody("mocked-data"));
  else
    route.resume();
});

Page routes take precedence over browser context routes (set up with BrowserContext.route()) when request matches both handlers.

To remove a route with its handler you can use Page.unroute().

note

Enabling routing disables http cache.

參數

  • url String | Pattern | Predicate<String>#

    A glob pattern, regex pattern, or predicate that receives a [URL] to match during routing. If setBaseURL is set in the context options and the provided URL is a string that does not start with *, it is resolved using the new URL() constructor.

  • handler Consumer<Route>#

    handler function to route the request.

  • options Page.RouteOptions (optional)

    • setTimes int (optional) Added in: v1.15#

      How often a route should be used. By default it will be used every time.

傳回值

routeFromHAR​

Added in: v1.23 page.routeFromHAR

If specified the network requests that are made in the page will be served from the HAR file. Read more about Replaying from HAR.

Playwright will not serve requests intercepted by Service Worker from the HAR file. See this issue. We recommend disabling Service Workers when using request interception by setting setServiceWorkers to 'block'.

使用方式

Page.routeFromHAR(har);
Page.routeFromHAR(har, options);

參數

  • har Path#

    Path to a HAR file with prerecorded network data. If path is a relative path, then it is resolved relative to the current working directory.

  • options Page.RouteFromHAROptions (optional)

    • setNotFound enum HarNotFound { ABORT, FALLBACK } (optional)#

      • If set to 'abort' any request not found in the HAR file will be aborted.
      • If set to 'fallback' missing requests will be sent to the network.

      Defaults to abort.

    • setUpdate boolean (optional)#

      If specified, updates the given HAR with the actual network information instead of serving from file. The file is written to disk when BrowserContext.close() is called.

    • setUpdateContent enum RouteFromHarUpdateContentPolicy { EMBED, ATTACH } (optional) Added in: v1.32#

      Optional setting to control resource content management. If attach is specified, resources are persisted as separate files or entries in the ZIP archive. If embed is specified, content is stored inline the HAR file.

    • setUpdateMode enum HarMode { FULL, MINIMAL } (optional) Added in: v1.32#

      When set to minimal, only record information necessary for routing from HAR. This omits sizes, timing, page, cookies, security and other types of HAR information that are not used when replaying from HAR. Defaults to minimal.

    • setUrl String | Pattern (optional)#

      A glob pattern, regular expression or predicate to match the request URL. Only requests with URL matching the pattern will be served from the HAR file. If not specified, all requests are served from the HAR file.

routeWebSocket​

Added in: v1.48 page.routeWebSocket

This method allows to modify websocket connections that are made by the page.

Note that only WebSockets created after this method was called will be routed. It is recommended to call this method before navigating the page.

使用方式

Below is an example of a simple mock that responds to a single message. See WebSocketRoute for more details and examples.

page.routeWebSocket("/ws", ws -> {
  ws.onMessage(frame -> {
    if ("request".equals(frame.text()))
      ws.send("response");

      The quality of the image, between 0-100. Not applicable to png images.

    • setScale enum ScreenshotScale { CSS, DEVICE } (optional)#

      When set to "css", screenshot will have a single pixel per each css pixel on the page. For high-dpi devices, this will keep screenshots small. Using "device" option will produce a single pixel per each device pixel, so screenshots of high-dpi devices will be twice as large or even larger.

      Defaults to "device".

    • setStyle String (optional) Added in: v1.41#

      Text of the stylesheet to apply while making the screenshot. This is where you can hide dynamic elements, make elements invisible or change their properties to help you creating repeatable screenshots. This stylesheet pierces the Shadow DOM and applies to the inner frames.

setViewportSize​

Added before v1.9 page.setViewportSize

In the case of multiple pages in a single browser, each page can have its own viewport size. However, Browser.newContext() allows to set viewport size (and more) for all pages in the context at once.

Page.setViewportSize() will resize the page. A lot of websites don't expect phones to change size, so you should set the viewport size before navigating to the page. Page.setViewportSize() will also reset screen size, use Browser.newContext() with screen and viewport parameters if you need better control of these properties.

使用方式

Page page = browser.newPage();
page.setViewportSize(640, 480);
page.navigate("https://example.com");

參數

  • width int Added in: v1.10#

    Page width in pixels.

waitForLoadState​

Added before v1.9 page.waitForLoadState

Returns when the required load state has been reached.

This resolves when the page reaches a required load state, load by default. The navigation must have been committed when this method is called. If current document has already reached the required state, resolves immediately.

note

Most of the time, this method is not needed because Playwright auto-waits before every action.

使用方式

page.getByRole(AriaRole.BUTTON).click(); // Click triggers navigation.
page.waitForLoadState(); // The promise resolves after "load" event.
Page popup = page.waitForPopup(() -> {
  page.getByRole(AriaRole.BUTTON).click(); // Click triggers a popup.
});
// Wait for the "DOMContentLoaded" event
popup.waitForLoadState(LoadState.DOMCONTENTLOADED);
System.out.println(popup.title()); // Popup is ready to use.

參數

使用方式

Page.onClose(handler)

事件資料

onConsoleMessage(handler)​

Added before v1.9 page.onConsoleMessage(handler)

});
page.evaluate("() => console.log('hello', 5, { foo: 'bar' })");

事件資料

onCrash(handler)​

Added before v1.9 page.onCrash(handler)

Emitted when the page crashes. Browser pages might crash if they try to allocate too much memory. When the page crashes, ongoing and subsequent operations will throw.

The most common way to deal with crashes is to catch an exception:

try {
  // Crash might happen during a click.
  page.click("button");
  // Or while waiting for an event.
  page.waitForPopup(() -> {});
} catch (PlaywrightException e) {
  // When the page crashes, exception message contains "crash".
}

使用方式

Page.onCrash(handler)

事件資料

onDialog(handler)​

Added before v1.9 page.onDialog(handler)

Emitted when a JavaScript dialog appears, such as alert, prompt, confirm or beforeunload. Listener must either Dialog.accept() or Dialog.dismiss() the dialog - otherwise the page will freeze waiting for the dialog, and actions like click will never finish.

使用方式

page.onDialog(dialog -> {
  dialog.accept();
});
note

When no Page.onDialog(handler) or BrowserContext.onDialog(handler) listeners are present, all dialogs are automatically dismissed.

事件資料

Added in: v1.9 page.onDOMContentLoaded(handler)

Emitted when the JavaScript DOMContentLoaded event is dispatched.

使用方式

Page.onDOMContentLoaded(handler)

事件資料

onDownload(handler)​

使用方式

Page.onDownload(handler)

事件資料

onFileChooser(handler)​

Added in: v1.9 page.onFileChooser(handler)

Emitted when a file chooser is supposed to appear, such as after clicking the <input type=file>. Playwright can respond to it via setting the input files using FileChooser.setFiles() that can be uploaded after that.

page.onFileChooser(fileChooser -> {
  fileChooser.setFiles(Paths.get("/tmp/myfile.pdf"));
});

使用方式

Page.onFileChooser(handler)

Emitted when an uncaught exception happens within the page.

// Log all uncaught errors to the terminal
page.onPageError(exception -> {
  System.out.println("Uncaught exception: " + exception);
});

// Navigate to a page with an exception.
page.navigate("data:text/html,<script>throw new Error('Test')</script>");

使用方式

Page.onPageError(handler)

事件資料

onPopup(handler)​

Added before v1.9 page.onPopup(handler)

Emitted when the page opens a new tab or window. This event is emitted in addition to the BrowserContext.onPage(handler), but only for popups relevant to this page.

The earliest moment that page is available is when it has navigated to the initial url. For example, when opening a popup with window.open('http://example.com'), this event will fire when the network request to "http://example.com" is done and its response has started loading in the popup. If you would like to route/listen to this network request, use BrowserContext.route() and BrowserContext.onRequest(handler) respectively instead of similar methods on the Page.

Page popup = page.waitForPopup(() -> {
  page.getByText("open the popup").click();
});
System.out.println(popup.evaluate("location.href"));
note

Use Page.waitForLoadState() to wait until the page gets to a particular state (you should not need it in most cases).

使用方式

Page.onPopup(handler)

事件資料

onRequest(handler)​

Added before v1.9 page.onRequest(handler)

Emitted when a page issues a request. The request object is read-only. In order to intercept and mutate requests, see Page.route() or BrowserContext.route().

事件資料

onRequestFailed(handler)​

Added in: v1.9 page.onRequestFailed(handler)

Emitted when a request fails, for example by timing out.

page.onRequestFailed(request -> {
  System.out.println(request.url() + " " + request.failure());
});
note

HTTP Error responses, such as 404 or 503, are still successful responses from HTTP standpoint, so request will complete with Page.onRequestFinished(handler) event and not with Page.onRequestFailed(handler). A request will only be considered failed when the client cannot get an HTTP response from the server, e.g. due to network error net::ERR_FAILED.

使用方式

Page.onRequestFailed(handler)

事件資料

onRequestFinished(handler)​

Added in: v1.9 page.onRequestFinished(handler)

check​

Added before v1.9 page.check
Discouraged

Use locator-based Locator.check() instead. Read more about locators.

This method checks an element matching selector by performing the following steps:

  1. Find an element matching selector. If there is none, wait until a matching element is attached to the DOM.
  2. Ensure that matched element is a checkbox or a radio input. If not, this method throws. If the element is already checked, this method returns immediately.
  3. Wait for actionability checks on the matched element, unless setForce option is set. If the element is detached during the checks, the whole action is retried.
  4. Scroll the element into view if needed.
  5. Use Page.mouse() to click in the center of the element.
  6. Ensure that the element is now checked. If not, this method throws.

When all steps combined have not finished during the specified setTimeout, this method throws a TimeoutError. Passing zero timeout disables this.

使用方式

Page.check(selector);
Page.check(selector, options);

參數

  • selector String#

    A selector to search for an element. If there are multiple elements satisfying the selector, the first will be used.

  • options Page.CheckOptions (optional)

    • setStrict boolean (optional) Added in: v1.14#

      When true, the call requires selector to resolve to a single element. If given selector resolves to more than one element, the call throws an exception.

    • setTimeout double (optional)#

      Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the BrowserContext.setDefaultTimeout() or Page.setDefaultTimeout() methods.

    • setTrial boolean (optional) Added in: v1.11#

      When set, this method only performs the actionability checks and skips the action. Defaults to false. Useful to wait until the element is ready for the action without performing it.

dispatchEvent​

Added before v1.9 page.dispatchEvent
Discouraged

Use locator-based Locator.dispatchEvent() instead. Read more about locators.

The snippet below dispatches the click event on the element. Regardless of the visibility state of the element, click is dispatched. This is equivalent to calling element.click().

使用方式

page.dispatchEvent("button#submit", "click");

Under the hood, it creates an instance of an event based on the given type, initializes it with eventInit properties and dispatches it on the element. Events are composed, cancelable and bubble by default.

Since eventInit is event-specific, please refer to the events documentation for the lists of initial properties:

You can also specify JSHandle as the property value if you want live objects to be passed into the event:

// Note you can only create DataTransfer in Chromium and Firefox
JSHandle dataTransfer = page.evaluateHandle("() => new DataTransfer()");
Map<String, Object> arg = new HashMap<>();
arg.put("dataTransfer", dataTransfer);
page.dispatchEvent("#source", "dragstart", arg);

參數

  • selector String#

    A selector to search for an element. If there are multiple elements satisfying the selector, the first will be used.

  • type String#

    DOM event type: "click", "dragstart", etc.

  • eventInit EvaluationArgument (optional)#

    Optional event-specific initialization properties.

  • options Page.DispatchEventOptions (optional)

    • setStrict boolean (optional) Added in: v1.14#

      When true, the call requires selector to resolve to a single element. If given selector resolves to more than one element, the call throws an exception.

evalOnSelector​

Added in: v1.9 page.evalOnSelector
Discouraged

This method does not wait for the element to pass actionability checks and therefore can lead to the flaky tests. Use Locator.evaluate(), other Locator helper methods or web-first assertions instead.

The method finds an element matching the specified selector within the page and passes it as a first argument to expression. If no elements match the selector, the method throws an error. Returns the value of expression.

If expression returns a Promise, then Page.evalOnSelector() would wait for the promise to resolve and return its value.

使用方式

String searchValue = (String) page.evalOnSelector("#search", "el => el.value");
String preloadHref = (String) page.evalOnSelector("link[rel=preload]", "el => el.href");
String html = (String) page.evalOnSelector(".main-container", "(e, suffix) => e.outerHTML + suffix", "hello");

參數

  • selector String#

    A selector to query for.

  • expression String#

    JavaScript expression to be evaluated in the browser context. If the expression evaluates to a function, the function is automatically invoked.

  • arg EvaluationArgument (optional)#

    Optional argument to pass to expression.

  • options Page.EvalOnSelectorOptions (optional)

    • setStrict boolean (optional) Added in: v1.14#

evalOnSelectorAll​

Added in: v1.9 page.evalOnSelectorAll
Discouraged

In most cases, Locator.evaluateAll(), other Locator helper methods and web-first assertions do a better job.

The method finds all elements matching the specified selector within the page and passes an array of matched elements as a first argument to expression. Returns the result of expression invocation.

If expression returns a Promise, then Page.evalOnSelectorAll() would wait for the promise to resolve and return its value.

使用方式

boolean divCounts = (boolean) page.evalOnSelectorAll("div", "(divs, min) => divs.length >= min", 10);

參數

  • selector String#

    A selector to query for.

  • expression String#

    JavaScript expression to be evaluated in the browser context. If the expression evaluates to a function, the function is automatically invoked.

  • arg EvaluationArgument (optional)#

If the target element is not an <input>, <textarea> or [contenteditable] element, this method throws an error. However, if the element is inside the <label> element that has an associated control, the control will be filled instead.

To send fine-grained keyboard events, use Locator.pressSequentially().

使用方式

Page.fill(selector, value);
Page.fill(selector, value, options);

參數

hover​

Added before v1.9 page.hover
Discouraged

Use locator-based Locator.hover() instead. Read more about locators.

This method hovers over an element matching selector by performing the following steps:

  1. Find an element matching selector. If there is none, wait until a matching element is attached to the DOM.
  2. Wait for actionability checks on the matched element, unless setForce option is set. If the element is detached during the checks, the whole action is retried.

Sets the value of the file input to these file paths or files. If some of the filePaths are relative paths, then they are resolved relative to the current working directory. For empty array, clears the selected files. For inputs with a [webkitdirectory] attribute, only a single directory path is supported.

This method expects selector to point to an input element. However, if the element is inside the <label> element that has an associated control, targets the control instead.

使用方式

Page.setInputFiles(selector, files);
Page.setInputFiles(selector, files, options);

參數

  • selector String#

    A selector to search for an element. If there are multiple elements satisfying the selector, the first will be used.

    • setStrict boolean (optional) Added in: v1.14#

      When true, the call requires selector to resolve to a single element. If given selector resolves to more than one element, the call throws an exception.

    • setTimeout double (optional)#

      Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the BrowserContext.setDefaultTimeout() or Page.setDefaultTimeout() methods.

tap​

Added before v1.9 page.tap
Discouraged

Use locator-based Locator.tap() instead. Read more about locators.

This method taps an element matching selector by performing the following steps:

  1. Find an element matching selector. If there is none, wait until a matching element is attached to the DOM.
  2. Wait for actionability checks on the matched element, unless setForce option is set. If the element is detached during the checks, the whole action is retried.
  3. Scroll the element into view if needed.
  4. Use Page.touchscreen() to tap the center of the element, or the specified setPosition.

When all steps combined have not finished during the specified setTimeout, this method throws a TimeoutError. Passing zero timeout disables this.

note

Page.tap() the method will throw if setHasTouch option of the browser context is false.

使用方式

Page.tap(selector);
Page.tap(selector, options);

參數

  • selector String#

    A selector to search for an element. If there are multiple elements satisfying the selector, the first will be used.

  • options Page.TapOptions (optional)

      Whether to bypass the actionability checks. Defaults to false.

    • setModifiers List<enum KeyboardModifier { ALT, CONTROL, CONTROLORMETA, META, SHIFT }> (optional)#

      Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores current modifiers back. If not specified, currently pressed modifiers are used. "ControlOrMeta" resolves to "Control" on Windows and Linux and to "Meta" on macOS.

    • setNoWaitAfter boolean (optional)#

      Deprecated

    • setStrict boolean (optional) Added in: v1.14#

      When true, the call requires selector to resolve to a single element. If given selector resolves to more than one element, the call throws an exception.

    • setTimeout double (optional)#

      Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the BrowserContext.setDefaultTimeout() or Page.setDefaultTimeout() methods.

    • setTrial boolean (optional) Added in: v1.11#

      When set, this method only performs the actionability checks and skips the action. Defaults to false. Useful to wait until the element is ready for the action without performing it. Note that keyboard modifiers will be pressed regardless of trial to allow testing elements which are only visible when those keys are pressed.

type​

Added before v1.9 page.type
Deprecated

In most cases, you should use Locator.fill() instead. You only need to press keys one by one if there is special keyboard handling on the page - in this case use Locator.pressSequentially().

Sends a keydown, keypress/input, and keyup event for each character in the text. page.type can be used to send fine-grained keyboard events. To fill values in form fields, use Page.fill().

To press a special key, like Control or ArrowDown, use Keyboard.press().

uncheck​

Added before v1.9 page.uncheck
Discouraged

Use locator-based Locator.uncheck() instead. Read more about locators.

This method unchecks an element matching selector by performing the following steps:

  1. Find an element matching selector. If there is none, wait until a matching element is attached to the DOM.
  2. Ensure that matched element is a checkbox or a radio input. If not, this method throws. If the element is already unchecked, this method returns immediately.
  3. Wait for actionability checks on the matched element, unless setForce option is set. If the element is detached during the checks, the whole action is retried.
  4. Scroll the element into view if needed.
  5. Use Page.mouse() to click in the center of the element.
  6. Ensure that the element is now unchecked. If not, this method throws.

When all steps combined have not finished during the specified setTimeout, this method throws a TimeoutError. Passing zero timeout disables this.

waitForNavigation​

Added before v1.9 page.waitForNavigation
Deprecated

This method is inherently racy, please use Page.waitForURL() instead.

Waits for the main frame navigation and returns the main resource response. In case of multiple redirects, the navigation will resolve with the response of the last redirect. In case of navigation to a different anchor or navigation due to History API usage, the navigation will resolve with null.

使用方式

This resolves when the page navigates to a new URL or reloads. It is useful for when you run code which will indirectly cause the page to navigate. e.g. The click target has an onclick handler that triggers navigation from a setTimeout. Consider this example:

// The method returns after navigation has finished
Response response = page.waitForNavigation(() -> {
  // This action triggers the navigation after a timeout.
  page.getByText("Navigate after timeout").click();
});
note

Usage of the History API to change the URL is considered a navigation.

參數

  • options Page.WaitForNavigationOptions (optional)

    • setTimeout double (optional)#

      Maximum operation time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the BrowserContext.setDefaultNavigationTimeout(), BrowserContext.setDefaultTimeout(), Page.setDefaultNavigationTimeout() or Page.setDefaultTimeout() methods.

    • setUrl String | Pattern | Predicate<String> (optional)#

      A glob pattern, regex pattern or predicate receiving [URL] to match while waiting for the navigation. Note that if the parameter is a string without wildcard characters, the method will wait for navigation to URL that is exactly equal to the string.

    • setWaitUntil enum WaitUntilState { LOAD, DOMCONTENTLOADED, NETWORKIDLE, COMMIT } (optional)#

      When to consider operation succeeded, defaults to load. Events can be either:

      • 'domcontentloaded' - consider operation to be finished when the DOMContentLoaded event is fired.
      • 'load' - consider operation to be finished when the load event is fired.
      • 'networkidle' - DISCOURAGED consider operation to be finished when there are no network connections for at least 500 ms. Don't use this method for testing, rely on web assertions to assess readiness instead.
      • 'commit' - consider operation to be finished when network response is received and the document started loading.

  • callback Runnable Added in: v1.9#

    Callback that performs the action triggering the event.

waitForSelector​

Added before v1.9 page.waitForSelector
Discouraged

Use web assertions that assert visibility or a locator-based Locator.waitFor() instead. Read more about locators.

Returns when element specified by selector satisfies setState option. Returns null if waiting for hidden or detached.

note

Playwright automatically waits for element to be ready before performing an action. Using Locator objects and web-first assertions makes the code wait-for-selector-free.

Wait for the selector to satisfy setState option (either appear/disappear from dom, or become visible/hidden). If at the moment of calling the method selector already satisfies the condition, the method will return immediately. If the selector doesn't satisfy the condition for the setTimeout milliseconds, the function will throw.

使用方式

This method works across navigations:

import com.microsoft.playwright.*;

public class Example {
  public static void main(String[] args) {
    try (Playwright playwright = Playwright.create()) {
      BrowserType chromium = playwright.chromium();
      Browser browser = chromium.launch();
      Page page = browser.newPage();
      for (String currentURL : Arrays.asList("https://google.com", "https://bbc.com")) {
        page.navigate(currentURL);
        ElementHandle element = page.waitForSelector("img");
        System.out.println("Loaded image: " + element.getAttribute("src"));
      }
      browser.close();
    }
  }
}

參數

  • selector String#

    A selector to query for.

  • options Page.WaitForSelectorOptions (optional)

    • setState enum WaitForSelectorState { ATTACHED, DETACHED, VISIBLE, HIDDEN } (optional)#

      Defaults to 'visible'. Can be either:

      • 'attached' - wait for element to be present in DOM.
      • 'detached' - wait for element to not be present in DOM.
      • 'visible' - wait for element to have non-empty bounding box and no visibility:hidden. Note that element without any content or with display:none has an empty bounding box and is not considered visible.
      • 'hidden' - wait for element to be either detached from DOM, or have an empty bounding box or visibility:hidden. This is opposite to the 'visible' option.

    • setStrict boolean (optional) Added in: v1.14#

      When true, the call requires selector to resolve to a single element. If given selector resolves to more than one element, the call throws an exception.

    • setTimeout double (optional)#

      Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the BrowserContext.setDefaultTimeout() or Page.setDefaultTimeout() methods.

waitForTimeout​

Added before v1.9 page.waitForTimeout
Discouraged

Never wait for timeout in production. Tests that wait for time are inherently flaky. Use Locator actions and web assertions that wait automatically.

Waits for the given timeout in milliseconds.

Note that page.waitForTimeout() should only be used for debugging. Tests using the timer in production are going to be flaky. Use signals such as network events, selectors becoming visible and others instead.
