Language Version: ActionScript 3.0
Runtime Versions: Flash Player 9, AIR 1.0

An object dispatches a DataEvent object when raw data has completed loading. There are two types of data event:
  • DataEvent.DATA: dispatched for data sent or received.
  • DataEvent.UPLOAD_COMPLETE_DATA: dispatched when data is sent and the server has responded.

()Constructor
public function DataEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, data:String = "")

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 9, AIR 1.0

Creates an event object that contains information about data events. Event objects are passed as parameters to event listeners.

Parameters
type:String — The type of the event. Event listeners can access this information through the inherited type property. There is only one type of data event: DataEvent.DATA.
 
bubbles:Boolean (default = false) — Determines whether the Event object participates in the bubbling phase of the event flow. Event listeners can access this information through the inherited bubbles property.
 
cancelable:Boolean (default = false) — Determines whether the Event object can be canceled. Event listeners can access this information through the inherited cancelable property.
 
data:String (default = "") — The raw data loaded into Flash Player or Adobe AIR. Event listeners can access this information through the data property.

DataEventExample.as

The following example creates an XMLSocket and connects it to a socket server running on port 8080 of yourDomain. An event listener is attached to the XMLSocket object that listens for data events, which are dispatched whenever raw data is received.

Notes:

  • To generate a securityError event in this example, you need to compile the SWF file with "Local playback security" set to "Access network only".
  • You need a server running on [yourDomain] using port 8080.

package {
    import flash.display.Sprite;
    import flash.events.DataEvent;
    import flash.net.XMLSocket;

    public class DataEventExample extends Sprite {
        private var hostName:String = "[yourDomain]";
        private var port:uint = 8080;
        private var socket:XMLSocket;

        public function DataEventExample() {
            socket = new XMLSocket();
            socket.addEventListener(DataEvent.DATA, dataHandler);
            socket.connect(hostName, port);
        }

        private function dataHandler(event:DataEvent):void {
            trace("dataHandler: " + event.data);
        }
    }
}
