This pulls in the types (based on the DefinitelyTyped repo) for `page.$eval` (and the `$eval` method on other classes). The `$eval` method is quite hard to type due to the way we wrap and unwrap ElementHandles that are passed to / returned from the `pageFunction` that users provide. Longer term we can improve the types by providing type overloads as DefinitelyTyped does but I've deferred that for now (see the `TODO` in the code for more details).

## JSHandle.evaluateHandle() method
|
|
|
|
This method passes this handle as the first argument to `pageFunction`<!-- -->.
|
|
|
|
<b>Signature:</b>
|
|
|
|
```typescript
|
|
evaluateHandle<HandleType extends JSHandle = JSHandle>(pageFunction: EvaluateHandleFn, ...args: SerializableOrJSHandle[]): Promise<HandleType>;
|
|
```
|
|
|
|
## Parameters
|
|
|
|
| Parameter | Type | Description |
|
|
| --- | --- | --- |
|
|
| pageFunction | [EvaluateHandleFn](./puppeteer.evaluatehandlefn.md) | |
|
|
| args | [SerializableOrJSHandle](./puppeteer.serializableorjshandle.md)<!-- -->\[\] | |
|
|
|
|
<b>Returns:</b>
|
|
|
|
Promise<HandleType>
|
|
|
|
## 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.
