waitForSelector<Selector extends string>(
selector: Selector,
options?: WaitForSelectorOptions
): Promise<ElementHandle<NodeFor<Selector>> | null>;
}
Parameters
Parameter | Type | Description |
---|---|---|
selector | Selector | The selector to query and wait for. |
options | WaitForSelectorOptions | (Optional) Options for customizing waiting behavior. |
Returns:
Promise<ElementHandle<NodeFor<Selector>> | null>
An element matching the given selector.
Exceptions
Throws if an element matching the given selector doesn't appear.
Example
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
let currentURL;
page
.mainFrame()
.waitForSelector('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();
})();
