flex和javascript互相调用的一个例子

flex 方面 :

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
    layout="absolute"
    creationComplete="initApp()"
    themeColor="#29AE58">
<mx:Button x="42"
      y="43"
      label="按钮"
      click="btn1_click()"
      enabled="true"
      labelPlacement="left">
</mx:Button>
<mx:Label id="Label1"
     x="132"
     y="45"
     text="Label"/>

<mx:Script>
  <![CDATA[
   import flash.external.*;
   import mx.controls.Alert;

   private function btn1_click():void
   {
    Label1.text="哈哈今年是2012";
   }

   public function dyjs():void
   {
    var f:String="js";
    var m:String=ExternalInterface.call(f);

}

   public function wsflex():Number
   {
    Alert.show("呵呵我是flex");

return 42;
}

   public function initApp():void
   {
    ExternalInterface.addCallback("dyflex", wsflex);
   }
  ]]>
</mx:Script>
<mx:RadioButtonGroup id="radiogroup1"/>
<mx:Button x="194"
      click="dyjs()"
      y="43"
      label="调用js"/>

</mx:Application>

html 方面

function js()
{
alert('我是js');
}

function dyflex()
{

     var a = document.getElementById("myname");
    var x = a.dyflex();
    //alert(x);
}

</script>

</head>
<body>
    <input id="Button1" type="button" value="button" onclick="dyflex();" />
    <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="myname" width="100%"
        height="100%" codebase="http://fpdownload.macromedia.com/get/flashplayer/current/swflash.cab">
        <param name="movie" value="test.swf" />
        <param name="quality" value="high" />
        <param name="bgcolor" value="#869ca7" />
        <param name="allowScriptAccess" value="sameDomain" />
        <embed src="test.swf" quality="high" bgcolor="#869ca7" width="100%" height="100%"
            name="sample19_5" align="middle" play="true" loop="false" quality="high" allowscriptaccess="sameDomain"
            type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer">
   </embed>
    </object>
</body>
</html>
