# ElementHandle class
|
|
|
|
ElementHandle represents an in-page DOM element.
|
|
|
|
#### Signature:
|
|
|
|
```typescript
|
|
export declare abstract class ElementHandle<ElementType extends Node = Element> extends JSHandle<ElementType>
|
|
```
|
|
|
|
**Extends:** [JSHandle](./puppeteer.jshandle.md)<ElementType>
|
|
|
|
## Remarks
|
|
|
|
ElementHandles can be created with the [Page.$()](./puppeteer.page._.md) method.
|
|
|
|
```ts
|
|
import puppeteer from 'puppeteer';
|
|
|
|
(async () => {
|
|
const browser = await puppeteer.launch();
|
|
const page = await browser.newPage();
|
|
await page.goto('https://example.com');
|
|
const hrefElement = await page.$('a');
|
|
await hrefElement.click();
|
|
// ...
|
|
})();
|
|
```
|
|
|
|
ElementHandle prevents the DOM element from being garbage-collected unless the handle is [disposed](./puppeteer.jshandle.dispose.md). ElementHandles are auto-disposed when their origin frame gets navigated.
|
|
|
|
ElementHandle instances can be used as arguments in [Page.$eval()](./puppeteer.page._eval.md) and [Page.evaluate()](./puppeteer.page.evaluate.md) methods.
|
|
|
|
If you're using TypeScript, ElementHandle takes a generic argument that denotes the type of element the handle is holding within. For example, if you have a handle to a `<select>` element, you can type it as `ElementHandle<HTMLSelectElement>` and you get some nicer type checks.
|
|
|
|
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `ElementHandle` class.
