I don’t really understand the difference between these two

event.target and              

event.CurrentTarget and explanation.

Can somebody explain this to me on a simple example?

Answer 1

Suppose you create a TextInput object.

import fl.controls.TextInput;
import flash.events.MouseEvent;

var t:TextInput;

function init():void {
    t = new TextInput();
    t.x = 100;
    t.y = 100;
    t.width=100;
    t.height=30;
    t.addEventListener(MouseEvent.CLICK, fresult);
    this.addChild(t);
}

function fresult(e:Event):void {
    trace(e.target);
    trace(e.currentTarget);
}

init();

Clicking on the TextInput gives the trace of:

[object TextField]
[object TextInput]

This means:

event.target is the object from which the event originated. i.e. in this case, a TextField was clicked on, so the event originated from the TextField.

event.currentTarget is the object which called the listener. In this case, the TextInput called the listener, so the currentTarget is TextInput
