## ExecutionContext.evaluateHandle() method

<b>Signature:</b>

```typescript
evaluateHandle<HandleType extends JSHandle | ElementHandle = JSHandle>(pageFunction: EvaluateHandleFn, ...args: SerializableOrJSHandle[]): Promise<HandleType>;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  pageFunction | [EvaluateHandleFn](./puppeteer.evaluatehandlefn.md) | a function to be evaluated in the <code>executionContext</code> |
|  args | [SerializableOrJSHandle](./puppeteer.serializableorjshandle.md)\[\] | argument to pass to the page function |

<b>Returns:</b>

Promise&lt;HandleType&gt;

A promise that resolves to the return value of the given function as an in-page object (a [JSHandle](./puppeteer.jshandle.md)).

## Remarks

The only difference between `executionContext.evaluate` and `executionContext.evaluateHandle` is that `executionContext.evaluateHandle` returns an in-page object (a [JSHandle](./puppeteer.jshandle.md)). If the function passed to the `executionContext.evaluateHandle` returns a Promise, then `executionContext.evaluateHandle` would wait for the promise to resolve and return its value.

## Example 1


```js
const context = await page.mainFrame().executionContext();
const aHandle = await context.evaluateHandle(() => Promise.resolve(self));
aHandle; // Handle for the global object.

```

## Example 2

A string can also be passed in instead of a function.

```js
// Handle for the '3' * object.
const aHandle = await context.evaluateHandle('1 + 2');

```

## Example 3

JSHandle instances can be passed as arguments to the `executionContext.* evaluateHandle`:

```js
const aHandle = await context.evaluateHandle(() => document.body);
const resultHandle = await context.evaluateHandle(body => body.innerHTML, * aHandle);
console.log(await resultHandle.jsonValue()); // prints body's innerHTML
await aHandle.dispose();
await resultHandle.dispose();

```
