# webView(_:createWebViewModalDialogWith:)

Creates a modal window containing a web view that loads the specified request.

## Declaration

```swift
optional func webView(_ sender: WebView!, createWebViewModalDialogWith request: URLRequest!) -> WebView!
```

## Parameters

- `sender`: The web view that sent the message.
- `request`: The request to load.

## Return Value

Return Value The web view that is loading the specified request.

## Discussion

Discussion This method is invoked when JavaScript calls window.showModalDialog. It should create a new modal window containing the web view and initially hide the window. The webViewRunModal(_:) message is sent to the delegate to display the web view.
