# ElementHandle.waitForXPath() method
|
|
|
|
> Warning: This API is now obsolete.
|
|
>
|
|
> Use [ElementHandle.waitForSelector()](./puppeteer.elementhandle.waitforselector.md) 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 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.
|
|
>
|
|
> If `xpath` starts with `//` instead of `.//`, the dot will be appended automatically.
|
|
>
|
|
> This method works across navigation.
|
|
>
|
|
> ```ts
|
|
> 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();
|
|
> })();
|
|
> ```

waitForXPath(
|
|
xpath: string,
|
|
options?: {
|
|
visible?: boolean;
|
|
hidden?: boolean;
|
|
timeout?: number;
|
|
}
|
|
): Promise<ElementHandle<Node> | null>;
|
|
}
|
|
```
|
|
|
|
## Parameters
|
|
|
|
| Parameter | Type | Description |
|
|
| --------- | ---------------------------------------------------------- | --------------------------------------------------------------------------------------- |
|
|
| xpath | string | A [xpath](https://developer.mozilla.org/en-US/docs/Web/XPath) of an element to wait for |
|
|
| options | { visible?: boolean; hidden?: boolean; timeout?: number; } | <i>(Optional)</i> Optional waiting parameters |
|
|
|
|
**Returns:**
|
|
|
|
Promise<[ElementHandle](./puppeteer.elementhandle.md)<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()](./puppeteer.page.setdefaulttimeout.md) method.
