# Frame.evaluate() method

**Signature:**

```typescript
class Frame {evaluate<Params extends unknown[], Func extends EvaluateFunc<Params> = EvaluateFunc<Params>>(pageFunction: Func | string, ...args: Params): Promise<Awaited<ReturnType<Func>>>;}
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  pageFunction | Func \| string | a function that is run within the frame |
|  args | Params | arguments to be passed to the pageFunction |

**Returns:**

Promise&lt;Awaited&lt;ReturnType&lt;Func&gt;&gt;&gt;

## Remarks

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.
