2010年10月13号---as与js通信之as与js方法调用示例-优快云博客

as与js通信方法，两者方法互相调用：

上代码

as2.0 :

import flash.external.ExternalInterface;
_root.btn.onPress = function() {
	ExternalInterface.call("callServer");
}

ExternalInterface.addCallback("JSCallAS", null, myFunction);
function myFunction( str:String ){
	txt.text = str;
}

html 也即js端:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="zh_cn" lang="zh_cn">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>communicate</title>
<script language="JavaScript" type="text/javascript">
    var xmlHttp;
    function createXMLHttpRequest(){
    		if(window.ActiveXObject){
    				xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
    		}else if(window.XMLHttpRequest){
    				xmlHttp = new XMLHttpRequest();
    		}
    }
    function startRequest(){
    		createXMLHttpRequest();
    		xmlHttp.open("get","http://192.168.1.153:8080/",true);
    		xmlHttp.onReadyStateChange = getResult;
    		xmlHttp.send(null);
    		function getResult(){
    				if(xmlHttp.readyState == 4 && xmlHttp.status == 200){
    						alert(xmlHttp.responseText);
    				}
    		}
    }
    function callServer(){
       alert("get it!");
       //在这里发送请求，并且发出需要获取的参数
       createXMLHttpRequest();
       startRequest();
    }
    
    function jsFunction(){
    		document.getElementById("demo").JSCallAS("Yes, as get it!");
    }
</script>
</head>
<body bgcolor="#ffffff">
	<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0" width="550" height="400" id="demo" align="middle">
		<param name="allowScriptAccess" value="allways" />
		<param name="allowFullScreen" value="false" />
		<param name="movie" value="demo.swf" />
		<param name="quality" value="high" />
		<param name="bgcolor" value="#ffffff" />	
				<embed src="demo.swf" id="flash_ID" quality="high" bgcolor="#ffffff" width="550" height="400" name="demo" align="middle" allowScriptAccess="always" allowFullScreen="false" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
	</object>
	
	<input type="button" onClick="jsFunction()" text="jsCallAS" />
</body>

</html>

tips: <param name="allowScriptAccess" value="allways" />

这里的默认值是：samedomain，要修改为：allways ，这样才能允许互相调用。
