Alert.show(text, title, flags, parent, closeHandler(关闭时触发的事件));
flag : Alert.YES|Alert.NO|Alert.OK

class="" title="">简单的alert提示框说起.
先一起来看看官方文档的介绍:
public static show(
text:String,
title:String = class="tags" href="/tags/NULL.html" title=null>null,
flags:uint = mx.controls.Alert.OK,
parent:Sprite = class="tags" href="/tags/NULL.html" title=null>null,
clickListener:Function = class="tags" href="/tags/NULL.html" title=null>null,
iconClass:Class = class="tags" href="/tags/NULL.html" title=null>null,
defaultButton:uint = mx.controls.Alert.OK) : Alert

alert提供了一个主要的方法,就是show()方法,其实中的参数都已经很明白地列出来了,下面我自己能过一个小例子,将上面的应用进去,大家也可以发挥自己的想像,动手来试试;
