MovieClip.onUnload
Availability
Flash Player 6.
Usage
my_mc.onUnload = function() {
// your statements here
}
Parameters
None.
Returns
Nothing.
Description
Event handler; invoked in the first frame after the movie clip is removed from the Timeline. Flash
processes the actions associated with the
onUnload event handler before attaching any actions to
the affected frame. You must define a function that executes when the event handler is invoked.
You can define the function on the Timeline or in a class file that extends the MovieClip class or
is linked to a symbol in the library. For more information, see “Assigning a class to a movie clip
symbol” in Using ActionScript in Flash.
Example
The following example defines a function for the MovieClip.onUnload method that sends a
trace() action to the Output panel:
my_mc.onUnload = function () {
trace ("onUnload called");
};
