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

An object dispatches an ErrorEvent object when an error causes a network operation to fail. There is only one type of error event: ErrorEvent.ERROR.

The ErrorEvent class also serves as the base class for the AsyncErrorEvent, IOErrorEvent, SecurityErrorEvent, and SQLErrorEvent classes.

You can check for error events that do not have any listeners by using the debugger version of Flash Player or the AIR Debug Launcher (ADL) application. The debugger version of Flash Player or the AIR Debug Launcher (ADL) application displays these events as strings (defined by the text parameter of the ErrorEvent constructor).

ErrorEvent

()Constructor
public function ErrorEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, text:String = "", id:int = 0)

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

Creates an Event object that contains information about error 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 error event: ErrorEvent.ERROR.
 
bubbles:Boolean (default = false) — Determines whether the Event object bubbles. 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.
 
text:String (default = "") — Text to be displayed as an error message. Event listeners can access this information through the text property.
 
id:int (default = 0) — A reference number to associate with the specific error (supported in Adobe AIR only).

Defines the value of the type property of an error event object.

This event has the following properties:

PropertyValue
bubblesfalse
cancelablefalse; there is no default behavior to cancel.
currentTargetThe object that is actively processing the Event object with an event listener.
targetThe object experiencing a network operation failure.
textText to be displayed as an error message.

ErrorEventExample.as

The following example demonstrates the use of a single error handler (errorHandler()) that captures multiple types of error events. If there is an ioError event, the handler attempts to load from the network, which then throws a securityError.

Note: This example does not work if you have a file named MissingFile.xml in the same directory as your SWF file.

package {
    import flash.display.Sprite;
    import flash.net.URLLoader;
    import flash.net.URLRequest;
    import flash.events.*;

    public class ErrorEventExample extends Sprite {
        private var loader:URLLoader;
        private var request:URLRequest;
        
        public function ErrorEventExample() {
            loader = new URLLoader();
            loader.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
            loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, errorHandler);

            request = new URLRequest();
            loadFromFileSystem();
        }
        
        private function loadFromFileSystem():void {
            request.url = "MissingFile.xml";
            loader.load(request);
        }

        private function loadFromNetwork():void {
            request.url = "http://www.[yourDomain].com/MissingFile.xml";
            loader.load(request);
        }
        
        private function errorHandler(event:ErrorEvent):void {
            trace("errorHandler: " + event);
            if(event is IOErrorEvent) {
                loadFromNetwork();
            }
        }
    }
