这篇文章主要介绍了Actionscript与javascript交互实例程序(修改)的相关资料,本文介绍的非常详细，具有参考借鉴价值，需要的朋友可以参考下

mxml页面：

<?xml version="1.0" encoding="utf-8"?> 
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
xmlns:s="library://ns.adobe.com/flex/spark"

width="100%" height="100%" xmlns:code="http://code.google.com/p/flex-iframe/" 
creationComplete="initApp()"> 
<fx:Declarations> 
<!-- 将非可视元素（例如服务、值对象）放在此处 --> 
</fx:Declarations> 
<fx:Script> 
<![CDATA[ 
import flash.external.*; //引入ExternalInterface 
public function initApp():void 
{ 
ExternalInterface.addCallback("myJsFunction",myAsFuncn); 
button.addEventListener(MouseEvent.CLICK,buttonClick); 
} 
public function myAsFuncn(js:String):String 
{ 
return "js:"+js+"访问了as："+asInput.text; 
} 
private function buttonClick(event:MouseEvent):void 
{ 
trace(asInput.text); 
label.text = "as 调用 js ..."; 
var result:String = callJS(asInput.text); 
label.text = "返回值：" + result; 
} 
private function callJS(arg:String):String 
{ 
return ExternalInterface.call("jsMethod",arg); 
} 
private function asMethod(arg:String):String 
{ 
label.text = arg; 
return "js 调用了 as 成功！"; 
} 
]]> 
</fx:Script> 
<s:VGroup width="100%" height="100%"> 
<s:VGroup width="100%"> 
<mx:Button x="169.5" y="162" label="点击" fontSize="14" id="button"/> 
<mx:TextInput id="asInput" x="122" y="76"/> 
<s:Label id="label"/> 
</s:VGroup> 
</s:VGroup> 
<code:IFrame source="MyHtml.html" width="500" height="500"/> 
</s:Application>

html页面：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
<head> 
<title>MyHtml.html</title> 
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> 
<meta http-equiv="description" content="this is my page"> 
<meta http-equiv="content-type" content="text/html; charset=UTF-8"> 
<!--<link rel="stylesheet" type="text/css" href="./styles.css">--> 
<script language="JavaScript"> 
function callAs( ) 
{ 
var myFlexfun=document.getElementById("myFlexFun"); 
var result=myFlexfun.myJsFunction(jsinput.value); 
alert(result); 
mess.value=result; 
} 
function jsMethod(arg) { 
alert("as 调用 js 成功，参数为：" + arg); 
return ("as 调用 js 成功！"); 
} 
</script> 
</head> 
<body> 
<table> 
<tr> 
<td> 
<object id= "myFlexFun" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="400" height="300"> 
<param name="movie" value="test.swf" /> 
<param name="quality" value="high" /> 
<embed src="test.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="400" height="300"></embed> 
</object> 
</td> 
</tr> 
<tr> 
<td> 
<input type="input" id="jsinput"/> 
<input type="button" value="点我看效果" onclick="callAs()"/> 
<input type="input" id="mess"/> 
</td> 
</tr> 
</table> 
</body> 
</html>

如果试过以上的方法，会发现在被嵌入的Html见面中又嵌入了一个父级的swf文件，如下

这种情况显然不是我想要的结果。于是修改下代码，如下：

mxml页面

<?xml version="1.0" encoding="utf-8"?> 
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
xmlns:s="library://ns.adobe.com/flex/spark" 
xmlns:mx="library://ns.adobe.com/flex/mx" 
width="100%" height="100%" xmlns:code="http://code.google.com/p/flex-iframe/" 
creationComplete="initApp()"> 
<fx:Declarations> 
<!-- 将非可视元素（例如服务、值对象）放在此处 --> 
</fx:Declarations> 
<fx:Script> 
<![CDATA[ 
import flash.external.*; 
import mx.controls.Alert; 
import mx.rpc.events.ResultEvent; //引入ExternalInterface 
public function initApp():void 
{ 
ExternalInterface.addCallback("sayCallBack",callBack); 
} 
public function callBack(str:String):String{ 
return "Hello "+str; 
} 
protected function button1_clickHandler(event:MouseEvent):void 
{ 
ExternalInterface.call('sayHelloWorld',' Jim'); 
var array:Array = new Array(); 
array.push("a", "b","c","d","e"); 
myIFrame.callIFrameFunction('jsMethod',array,function(str:String):void{ 
label.text=str; 
}); 
} 
public static function str():String{ 
return "aaa"; 
} 
]]> 
</fx:Script> 
<s:VGroup width="100%" height="100%"> 
<s:BorderContainer width="100%" height="300" backgroundColor="#00ffaa"> 
<s:HGroup width="100%"> 
<s:Button label="调用js" click="button1_clickHandler(event)"/> 
<mx:Button x="169.5" y="162" label="点击" fontSize="14" id="button"/> 
<mx:TextInput id="asInput" x="122" y="76"/> 
<s:Label id="label"/> 
</s:HGroup> 
</s:BorderContainer> 
<s:BorderContainer width="100%" height="300"> 
<code:IFrame id="myIFrame" source="com/MyHtml.html" width="100%" height="100%"/> 
</s:BorderContainer> 
</s:VGroup> 
</s:Application>

html页面：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
<head> 
<title>MyHtml.html</title> 
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> 
<meta http-equiv="description" content="this is my page"> 
<meta http-equiv="content-type" content="text/html; charset=UTF-8"> 
<!--<link rel="stylesheet" type="text/css" href="./styles.css">--> 
<script language="JavaScript"> 
function callAs( ) 
{ 
var ifrm =window.parent.xiSwfUrlStr; 
if (ifrm) 
{ 
alert(ifrm); 
}else{ 
alert('false'); 
} 
} 
function jsMethod(arr) { 
alert("as 调用 js 成功，参数为："+arr[4]); 
return ("as 调用 js 成功！"); 
} 
function callA(){ 
var str=window.parent.document.getElementById("test").sayCallBack("Bill"); 
if (str) 
{ 
alert(str); 
mess.value=str; 
}else{ 
alert('false'); 
} 
} 
</script> 
</head> 
<body> 
<table> 
<tr> 
<td > 
<object id= "myFlexFun" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="100%" height="100%"> 
<param name="movie" value="../test.swf" /> 
<param name="quality" value="high" /> 
</object> 
</td> 
</tr> 
<tr> 
<td> 
<input type="input" id="jsinput"/> 
<input type="button" value="点我看效果" onclick="callA()"/> 
<input type="input" id="mess"/> 
</td> 
</tr> 
</table> 
</body> 
</html>

这样，html的js脚本就可以直接调用as脚本，而不需要再次嵌入swf文件。
