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).

errorID | property |
errorID:int
[read-only] Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0, AIR 1.0 |

For a custom ErrorEvent object, this number is the value from the id
parameter supplied in the constructor.
Implementation
public function get errorID():int
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.
Parameterstype: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).
|
clone | () | method |
override public function clone():Event
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.0 |
Creates a copy of the ErrorEvent object and sets the value of each property to match that of the original.
ReturnsEvent — A new ErrorEvent object with property values that match those of the original.
|
toString | () | method |
override public function toString():String
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.0 |
Returns a string that contains all the properties of the ErrorEvent object. The string is in the following format:
[ErrorEvent type=value bubbles=value cancelable=value text=value errorID=value]
String — A string that contains all the properties of the ErrorEvent object.
|
ERROR | Constant |
public static const ERROR:String = "error"
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.0 |
Defines the value of the type
property of an error
event object.
This event has the following properties:
Property | Value |
---|---|
bubbles | false |
cancelable | false ; there is no default behavior to cancel. |
currentTarget | The object that is actively processing the Event object with an event listener. |
target | The object experiencing a network operation failure. |
text | Text to be displayed as an error message. |
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.
