# WebPage.DialogPresenting

Allows providing custom behavior to handle JavaScript actions and provide a response.

## Declaration

```swift
protocol DialogPresenting
```

## Overview

Overview Typically when handling these, some UI should be presented to the user for them to provide a response, which will then be communicated back to JavaScript. When these methods are invoked, JavaScript is blocked until the async method returns.
