Page.waitForXPath() method

Wait for the xpath to appear in page. If at the moment of calling the method the xpath already exists, the method will return immediately. If the xpath doesn't appear after the timeout milliseconds of waiting, the function will throw.

Signature:

class Page {
  waitForXPath(
    xpath: string,
    options?: WaitForSelectorOptions
  ): Promise<ElementHandle<Node> | null>;
}

Parameters

Parameter	Type	Description
xpath	string	A xpath of an element to wait for
options	WaitForSelectorOptions	(Optional) Optional waiting parameters

Returns:

Promise<ElementHandle<Node> | null>

Promise which resolves when element specified by xpath string is added to DOM. Resolves to null if waiting for hidden: true and xpath is not found in DOM, otherwise resolves to ElementHandle.

Remarks

The optional Argument options have properties:

• visible: A boolean to wait for element to be present in DOM and to be visible, i.e. to not have display: none or visibility: hidden CSS properties. Defaults to false.

• hidden: A boolean wait for element to not be found in the DOM or to be hidden, i.e. have display: none or visibility: hidden CSS properties. Defaults to false.

• timeout: A number which is maximum time to wait for in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the Page.setDefaultTimeout() method.

Example

This method works across navigation

import puppeteer from 'puppeteer';
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  let currentURL;
  page
    .waitForXPath('//img')
    .then(() => console.log('First URL with image: ' + currentURL));
  for (currentURL of [
    'https://example.com',
    'https://google.com',
    'https://bbc.com',
  ]) {
    await page.goto(currentURL);
  }
  await browser.close();
})();
