# removeScriptMessageHandler(forName:)

Uninstalls the custom message handler with the specified name from your JavaScript code.

## Declaration

```swift
func removeScriptMessageHandler(forName name: String)
```

## Parameters

- `name`: The name of the message handler to remove. If no message handler with this name exists in the user content controller, this method does nothing.

## Discussion

Discussion Use this method to remove a message handler that you previously installed using the add(_:name:) method. This method removes the message handler from the page content world — that is, the content world available from the page property of WKContentWorld. If you installed the message handler in a different content world, this method doesn’t remove it.
