# ExecutionContext.evaluate() method
|
|
||||||
|
|
||||||
Evaluates the given function.
|
|
||||||
|
|
||||||
**Signature:**
|
|
||||||
|
|
||||||
```typescript
|
|
||||||
class ExecutionContext {
|
|
||||||
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 | The function to evaluate. |
|
|
||||||
| args | Params | Additional arguments to pass into the function. |
|
|
||||||
|
|
||||||
**Returns:**
|
|
||||||
|
|
||||||
Promise<Awaited<ReturnType<Func>>>
|
|
||||||
|
|
||||||
The result of evaluating the function. If the result is an object, a vanilla object containing the serializable properties of the result is returned.
|
|
||||||
|
|
||||||
## Example 1
|
|
||||||
|
|
||||||
```ts
|
|
||||||
const executionContext = await page.mainFrame().executionContext();
|
|
||||||
const result = await executionContext.evaluate(() => Promise.resolve(8 * 7))* ;
|
|
||||||
console.log(result); // prints "56"
|
|
||||||
```
|
|
||||||
|
|
||||||
## Example 2
|
|
||||||
|
|
||||||
A string can also be passed in instead of a function:
|
|
||||||
|
|
||||||
```ts
|
|
||||||
console.log(await executionContext.evaluate('1 + 2')); // prints "3"
|
|
||||||
```
|
|
||||||
|
|
||||||
## Example 3
|
|
||||||
|
|
||||||
Handles can also be passed as `args`. They resolve to their referenced object:
|
|
||||||
|
|
||||||
```ts
|
|
||||||
const oneHandle = await executionContext.evaluateHandle(() => 1);
|
|
||||||
const twoHandle = await executionContext.evaluateHandle(() => 2);
|
|
||||||
const result = await executionContext.evaluate(
|
|
||||||
(a, b) => a + b,
|
|
||||||
oneHandle,
|
|
||||||
twoHandle
|
|
||||||
);
|
|
||||||
await oneHandle.dispose();
|
|
||||||
await twoHandle.dispose();
|
|
||||||
console.log(result); // prints '3'.
|
|
||||||

# ExecutionContext.evaluateHandle() method
|
|
||||||
|
|
||||||
Evaluates the given function.
|
|
||||||
|
|
||||||
Unlike [evaluate](./puppeteer.executioncontext.evaluate.md), this method returns a handle to the result of the function.
|
|
||||||
|
|
||||||
This method may be better suited if the object cannot be serialized (e.g. `Map`) and requires further manipulation.
|
|
||||||
|
|
||||||
**Signature:**
|
|
||||||
|
|
||||||
```typescript
|
|
||||||
class ExecutionContext {
|
|
||||||
evaluateHandle<
|
|
||||||
Params extends unknown[],
|
|
||||||
Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
|
|
||||||
>(
|
|
||||||
pageFunction: Func | string,
|
|
||||||
...args: Params
|
|
||||||
): Promise<HandleFor<Awaited<ReturnType<Func>>>>;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## Parameters
|
|
||||||
|
|
||||||
| Parameter | Type | Description |
|
|
||||||
| ------------ | -------------- | ----------------------------------------------- |
|
|
||||||
| pageFunction | Func \| string | The function to evaluate. |
|
|
||||||
| args | Params | Additional arguments to pass into the function. |
|
|
||||||
|
|
||||||
**Returns:**
|
|
||||||
|
|
||||||
Promise<[HandleFor](./puppeteer.handlefor.md)<Awaited<ReturnType<Func>>>>
|
|
||||||
|
|
||||||
A [handle](./puppeteer.jshandle.md) to the result of evaluating the function. If the result is a `Node`, then this will return an [element handle](./puppeteer.elementhandle.md).
|
|
||||||
|
|
||||||
## Example 1
|
|
||||||
|
|
||||||
```ts
|
|
||||||
const context = await page.mainFrame().executionContext();
|
|
||||||
const handle: JSHandle<typeof globalThis> = await context.evaluateHandle(() =>
|
|
||||||
Promise.resolve(self)
|
|
||||||
);
|
|
||||||
```
|
|
||||||
|
|
||||||
## Example 2
|
|
||||||
|
|
||||||
A string can also be passed in instead of a function.
|
|
||||||
|
|
||||||
```ts
|
|
||||||
const handle: JSHandle<number> = await context.evaluateHandle('1 + 2');
|
|
||||||
```
|
|
||||||
|
|
||||||
## Example 3
|
|
||||||

|
||||||
Handles can also be passed as `args`. They resolve to their referenced object:
|
|
||||||
|
|
||||||
```ts
|
|
||||||
const bodyHandle: ElementHandle<HTMLBodyElement> = await context.evaluateHandle(
|
|
||||||

||||||

}
|

body => body.innerHTML,
|
|

|
|
||||||
);
|
|
||||||
console.log(await stringHandle.jsonValue()); // prints body's innerHTML
|

// Always dispose your garbage! :)
|

await bodyHandle.dispose();
|
|

await stringHandle.dispose();

## Remarks
|

|

Besides pages, execution contexts can be found in [workers](./puppeteer.webworker.md).

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `ExecutionContext` class.
|
|
||||||
|
|
||||||
## Example
|
|
||||||
|
|
||||||
A [Page](./puppeteer.page.md) can have several execution contexts:
|
|
||||||
|
|
||||||
- Each [Frame](./puppeteer.frame.md) of a [page](./puppeteer.page.md) has a "default" execution context that is always created after frame is attached to DOM. This context is returned by the [Frame.executionContext()](./puppeteer.frame.executioncontext.md) method. - Each [Chrome extensions](https://developer.chrome.com/extensions) creates additional execution contexts to isolate their code.
