# webView(_:runJavaScriptConfirmPanelWithMessage:initiatedBy:)

Displays a JavaScript confirmation panel with the specified message.

```
optional func webView(_ sender: WebView!, runJavaScriptConfirmPanelWithMessage message: String!, initiatedBy frame: WebFrame!) -> Bool
```

## Parameters

`sender`

The web view that sent the message.

`message`

The message to display in the confirmation panel.

`frame`

The web frame whose JavaScript initiated this call.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the user clicks OK; otherwise, <doc://com.apple.documentation/documentation/Swift/false>.

## Discussion

This method displays a confirmation panel when JavaScript code calls `confirm`. Delegates should visually indicate that this panel comes from JavaScript. The panel should contain an OK and a Cancel button. No action is taken if you do not implement this method.
