Constant Detail

### INVALIDATE_LOADER

Constant

`public static const INVALIDATE_LOADER:String = "invalidateLoader"`

Language Version: | ActionScript 3.0

Product Version: | Flex 4

Runtime Versions: | Flash Player 9, AIR 1.1

The `LoaderInvalidationEvent.INVALIDATE_LOADER` constant defines the value of the `type` property of the event object for a `invalidateLoader` event.

The properties of the event object have the following values:

Property | Value
--- | ---
`bubbles` | false
`cancelable` | false
`content` | The content for which to invalidate the content request.
`currentTarget` | The Object that defines the event listener that handles the event. For example, if you use `myDataGrid.addEventListener()` to register an event listener, myDataGrid is the value of the `currentTarget`.
`target` | The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
`type` | LoaderInvalidationEvent.INVALIDATE_LOADER
