建一个Action Script 3.0文档，目标设置为Flash Player 11.2。

舞台放置1个输入文本txt1，1个动态文本txt2，1个按钮btn1。文档的类设置为com.elight.Main。

com.elight.Main代码如下：

package com.elight {
	import flash.display.MovieClip;
	import flash.events.*;
	import com.victop.MD5;

	public class Main extends MovieClip {

		public function Main() {
			addEventListener(Event.ADDED_TO_STAGE, addedHandle);
		}

		private function addedHandle(e:Event):void {
			removeEventListener(Event.ADDED_TO_STAGE, addedHandle);
			btn1.addEventListener(MouseEvent.CLICK, clickHandle);
		}

		private function clickHandle(e:MouseEvent):void {
			var s1:String = txt1.text;
			if (s1 == "") return;
			var md5:MD5 = new MD5;
			txt2.text = md5.getMD5(s1);
		}
	}
}

package com.elight {

import flash.display.MovieClip;

import flash.events.*;

import com.victop.MD5;

public class Main extends MovieClip {

public function Main() {

addEventListener(Event.ADDED_TO_STAGE, addedHandle);

}

private function addedHandle(e:Event):void {

removeEventListener(Event.ADDED_TO_STAGE, addedHandle);

btn1.addEventListener(MouseEvent.CLICK, clickHandle);

}

private function clickHandle(e:MouseEvent):void {

var s1:String = txt1.text;

if (s1 == "") return;

var md5:MD5 = new MD5;

txt2.text = md5.getMD5(s1);

}
