Flex 2和JavaScript交互

在Flex开发的时候,经常遇到一些问题处理起来比较麻烦.这个时候调用html页面里的js代码就成了最快的解决方案.flex主要是通过ExternalInterface.call来调用页面的代码,下面的例子是不需要返回值的调用. joinmeet.mxml
代码 <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="200" height="150"> <mx:Script>    <![CDATA[    import flash.external.*;
   public function Joinmeet() : void {       var f : String = "showsubmenu";       var m : String = ExternalInterface.call(f,"0");       trace(m);    }
   public function callWrapper():void {       var f:String = "changeDocumentTitle";       var m:String = ExternalInterface.call(f,"New Title");       trace(m);    }    ]]> </mx:Script> <mx:Button label="提交" click="Joinmeet()" x="123" y="118"/> </mx:Application>
