# JSHandle.evaluateHandle() method
|
||
|
|
||
|
This method passes this handle as the first argument to `pageFunction`.
|
||
|
|
||
|
**Signature:**
|
||
|
|
||
|
```typescript
|
||
|
class JSHandle {
|
||
|
evaluateHandle<
|
||
|
Params extends unknown[],
|
||
|
Func extends EvaluateFunc<[this, ...Params]> = EvaluateFunc<
|
||
|
[this, ...Params]
|
||
|
>
|
||
|
>(
|
||
|
pageFunction: Func | string,
|
||
|
...args: Params
|
||
|
): Promise<HandleFor<Awaited<ReturnType<Func>>>>;
|
||
|
}
|
||
|
```
|
||
|
|
||
|
## Parameters
|
||
|
|
||
|
| Parameter | Type | Description |
|
||
|
| ------------ | -------------- | ----------- |
|
||
|
| pageFunction | Func \| string | |
|
||
|
| args | Params | |
|
||
|
|
||
|
**Returns:**
|
||
|
|
||
|
Promise<[HandleFor](./puppeteer.handlefor.md)<Awaited<ReturnType<Func>>>>
|
||
|
|
||
|
## Remarks
|
||
|
|
||
|
The only difference between `jsHandle.evaluate` and `jsHandle.evaluateHandle` is that `jsHandle.evaluateHandle` returns an in-page object (JSHandle).
|
||
|
|
||
|
If the function passed to `jsHandle.evaluateHandle` returns a Promise, then `evaluateHandle.evaluateHandle` waits for the promise to resolve and returns its value.
|
||
|
|
||
|
See [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md) for more details.
