TextArea.change
Availability
Flash Player 6 (6.0 79.0).
Edition
Flash MX 2004.
Usage
Usage 1:
on(change){
...
}
Usage 2:
listenerObject = new Object();
listenerObject.change = function(eventObject){
...
}
textAreaInstance.addEventListener("change", listenerObject)
Description
Event; notifies listeners that text has changed. This event is broadcast after the text has changed.
This event cannot be used to prevent certain characters from being added to the component’s text
field; for this purpose, use
TextArea.restrict.
The first usage example uses an
on() handler and must be attached directly to a TextArea
instance. The keyword
this, used inside an on() handler attached to a component, refers to the
component instance. For example, the following code, attached to the instance
myTextArea,
sends “_level0.myTextArea” to the Output panel:
on(change){
trace(this);
}
Event Description
UIComponent.focusIn Broadcast when an object receives focus.
UIComponent.focusOut Broadcast when an object loses focus.
UIComponent.keyDown Broadcast when a key is pressed.
UIComponent.keyUp Broadcast when a key is released.
