<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
	<mx:Script>
		<![CDATA[
			private function clickFunction():void{
				btn.enabled = false;
				setTimeout(clickBack,30000);//三十秒
			}
			
			private function clickBack():void{
				btn.enabled  = true;
			}
		]]>
	</mx:Script>
	<mx:Canvas id="main" width="100%" height="100%">
		<mx:Button id="btn" label="点击" click="clickFunction()" />
	</mx:Canvas>
</mx:Application>

Timmer类很好控制

disable或removeEventListener都可以

	<mx:Script>
		<![CDATA[
		    public var i:int = 30;
		    public var intervalId:Number;//定时器参数 
			private function clickFunction():void{
				i = 30;
				btn.enabled = false;
				setTimeout(clickBack,30000);//三十秒
				intervalId = setInterval(NumAdd,1000);
			}
			
			private function clickBack():void{
				btn.enabled  = true;
			}
			
			private function NumAdd():void{
				i--;
				if(i==0){
					clearInterval(intervalId);
					show.text="";
				}
				else
					show.text = "距离按钮恢复还有" + i + "秒";
			}
		]]>
	</mx:Script>
	<mx:Canvas id="main" width="100%" height="100%">
		<mx:Button id="btn" x="100" y="100" label="点击" click="clickFunction()" />
		<mx:Label id="show" x="100" y="120" />
	</mx:Canvas>
</mx:Application>

这个比较清晰
