Flex中如何给一个按钮添加链接，点击链接打开一个网页呢？
可以用 navigateToURL 或者 htmlText 实现，请看下面的例子
<?xml version="1.0" encoding="utf-8"?>         

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="initApp()"         

layout="absolute" width="278" height="244">         

<mx:Script>         

     <![CDATA[         

             

         internal function initApp():void{         

            var str:String = "<a target='_blank' href='http://sucre.blog.51cto.com/'>paraliseinhell</a>";         

             link.htmlText = str;         

         }         

                 

         internal function openUrl():void{         

             navigateToURL(new URLRequest("http://sucre.blog.51cto.com/"), "_blank");         

         }         

     ]]>         

</mx:Script>         

     <mx:Button x="72" y="117" label="paraliseinhell" fontSize="13" id="link2" click="openUrl()"/>         

     <mx:Text id="link" text="paraliseinhell" x="72" y="47" fontSize="13"/>         

</mx:Application>
