Dialog

Dialog objects are dispatched by page via the page.on('dialog') event.

An example of using Dialog class:

const { chromium } = require('playwright');  // Or 'firefox' or 'webkit'.

(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage();
  page.on('dialog', async dialog => {
    console.log(dialog.message());
    await dialog.dismiss();
  });
  await page.evaluate(() => alert('1'));
  await browser.close();
})();
note

Dialogs are dismissed automatically, unless there is a page.on('dialog') 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.
