<b>Signature:</b>

```typescript
evaluate<T extends EvaluateFn>(pageFunction: T, ...args: SerializableOrJSHandle[]): Promise<UnwrapPromiseLike<EvaluateFnReturnType<T>>>;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  pageFunction | T | a function that is run within the frame |
|  args | [SerializableOrJSHandle](./puppeteer.serializableorjshandle.md)\[\] | arguments to be passed to the pageFunction |

<b>Returns:</b>

Promise&lt;[UnwrapPromiseLike](./puppeteer.unwrappromiselike.md)&lt;[EvaluateFnReturnType](./puppeteer.evaluatefnreturntype.md)&lt;T&gt;&gt;&gt;

This method behaves identically to [Page.evaluate()](./puppeteer.page.evaluate.md) except it's run within the context of the `frame`, rather than the entire page.
