Dialog

Dialog objects are dispatched by page via the Page.onDialog(handler) event.

An example of using Dialog class:

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();
      page.onDialog(dialog -> {
        System.out.println(dialog.message());
        dialog.dismiss();
      });
      page.evaluate("alert('1')");
      browser.close();
    }
  }
}
note

Dialogs are dismissed automatically, unless there is a Page.onDialog(handler) listener. When listener is present, it 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.
