Action Script 3 Static Method - actionscript-3

Question

I'm new to Action-script OOP and i need to know how to chain methods like this example i have
I.$(button).bind('click',clickButton).bind('rollover',overButton).bind('rollout',outButton)
First i need to remove the I. to use dollar sign only like jQuery :) to select MovieClip and apply any action on it second issue that i have because this way i'm using static Methods Action-script restrict's me to use only static property saving the last one who called the action here is the class code to know what i mean:
package com.MAIN
{
import flash.display.Sprite;
import flash.events.MouseEvent;
public class I extends Sprite
{
private static var cSelector:Sprite;
public static function $(selector:Sprite)
{
cSelector = selector
return I;
}
public static function alpha(val:Number)
{
cSelector.alpha = val;
return I;
}
// bind mouse event to the element
public static function bind(EventStr,func:Function)
{
var func1:Function = function(e:MouseEvent){
func(cSelector);
}
// select the event from the list
if(typeof(EventStr) == 'string'){
// map the events in lowercase
var events:Object = {click:'CLICK',rollover:'ROLL_OVER',rollout:'ROLL_OUT',dblclick:'DOUBLE_CLICK',mousedown:'MOUSE_DOWN',mousemove:'MOUSE_MOVE',mouseout:'MOUSE_OUT',mouseover:'MOUSE_OVER',mouseup:'MOUSE_UP',mousewheel:'MOUSE_WHEEL'};
// check if the event exists in the list
if(events[EventStr] && MouseEvent[events[EventStr]]){
cSelector.addEventListener(MouseEvent[events[EventStr]],func1);
}
}else if(typeof(EventStr) == 'object'){
// add the event
cSelector.addEventListener(EventStr,func1);
}
return I;
}
public static function remove()
{
cSelector.parent.removeChild(cSelector);
return I;
}
}
}

Answer 1

Here you go, some steps in the right direction. However, this is a really, really, really crappy idea.
//$.as
package
{
import flash.display.DisplayObject;
//NOTE: there's NO class definition
public function $( selector : DisplayObject ) : IDisplayObject
{
//traverse displaylist to find <code>selector</code>
//and return an instance of IDisplayObject that holds the reference
}
}
//IDisplayObject.as
package
{
public interface IDisplayObject{
function alpha( value : Number ) : IBinding;
}
}
//IBinding.as
package jquery
{
public interface IBinding{
function bind( eventName : String, callback : Function, ...parameters ):void;
}
}
Once you've created concrete implementations of these you can do:
$( someMC ).alpha( .5 ).bind( 'click', function(){ trace( 'what a miraculously crappy idea !!!!' ) } );

You could try it like this:
interface Test {
function doBla(): Test
function moreBla(): Test
}
public class StaticTest {
private static const instance: Test = new InternalTest()
public static doBla() : Test {
return instance.doBla();
}
public static moreBla() : Test {
return instance.moreBla();
}
}
internal class InternalTest implements Test {
function doBla(): Test {
trace("bla");
return this;
}
function moreBla(): Test {
trace("more bla");
return this;
}
}
