# webView(_:runJavaScriptTextInputPanelWithPrompt:defaultText:initiatedByFrame:completionHandler:)

Displays a JavaScript text input panel.

```
optional func webView(_ webView: WKWebView, runJavaScriptTextInputPanelWithPrompt prompt: String, defaultText: String?, initiatedByFrame frame: WKFrameInfo, completionHandler: @escaping @MainActor @Sendable (String?) -> Void)
```

## Parameters

`webView`

The web view invoking the delegate method.

`prompt`

The message to be displayed.

`defaultText`

The initial text to display in the text entry field.

`frame`

Information about the frame whose JavaScript process initiated this call.

`completionHandler`

The completion handler to call after the text input panel has been dismissed. Pass the entered text if the user chose OK, otherwise `nil`.

## Discussion

For user security, implementations of this method should call attention to the fact that a specific website controls the content in this panel. A simple formula for identifying the controlling website is `frame.request.URL.host`. The panel should have two buttons (typically OK and Cancel) and a field in which to enter text.
