ElementHandle.waitForXPath |
ElementHandle.waitForXPath() method
Warning: This API is now obsolete.
Use ElementHandle.waitForSelector() with the
xpath
prefix.Example:
await elementHandle.waitForSelector('xpath/' + xpathExpression)
The method evaluates the XPath expression relative to the elementHandle.
Wait for the
xpath
within the element. If at the moment of calling the method thexpath
already exists, the method will return immediately. If thexpath
doesn't appear after thetimeout
milliseconds of waiting, the function will throw.If
xpath
starts with//
instead of.//
, the dot will be appended automatically.This method works across navigation.
const puppeteer = require('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(); })();
