关于flash as脚本和web的通讯问题

HengStar 2010-06-17 04:46:08

我想实现as脚本和web的接口互调通信，今天上网搜了下可以在as中通过ExternalInterface.call调用外部（如javascript之类）的函数，我在Flash中第一帧写了如下代码



function cn(n)

{

	numberAni.text = (Math.random()*n).toString();

}



function lp(m)

{

	if(ExternalInterface.available)

	{

		ExternalInterface.call("getNumber");

		setInterval(cn, 100, 15);

	}

	else

	{

		setInterval(cn, 100, 99);

		trace("NONO");

	}

}



btn_Start.addEventListener(MouseEvent.CLICK,lp);

html中的代码如下

<html>

 <head>

 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

 <title>ExternalInterfaceExample</title>

 <script language="JavaScript">

    function getNumber()

    {

	alert("!!!!");

        return 15;

    }



     var jsReady = false;

     function isReady() {

         return jsReady;

     }

     function pageInit() {

         jsReady = true;

         document.forms["form1"].output.value += "\n" + "JavaScript is ready.\n";

     }

     function thisMovie(movieName) {

         if (navigator.appName.indexOf("Microsoft") != -1) {

             return window[movieName];

         } else {

             return document[movieName];

         }

     }

     function sendToActionScript(value) {

         thisMovie("ExternalInterfaceExample").sendToActionScript(value);

     }

     function sendToJavaScript(value) {

         document.forms["form1"].output.value += "ActionScript says: " + value + "\n";

     }

 </script>

 </head>

 <body onload="pageInit();">

 

     <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"

             id="testAs" name="testAs" width="500" height="375"

             type="application/x-shockwave-flash"

         </embed>

     </object>

 

     <form name="form1" onsubmit="return false;">

         <input type="text" name="input" value="" />

         <input type="button" value="Send" onclick="sendToActionScript(this.form.input.value);" /><br />

         <textarea cols="60" rows="20" name="output" readonly="true">Initializing...</textarea>

     </form>
