2013-01-28 17:07 423 查看

生成flash的mxml文件源码如下：

<?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" minWidth="955" minHeight="600" creationComplete="app(event)" >

<fx:Declarations>



</fx:Declarations>

<fx:Script>

<![CDATA[

import mx.events.FlexEvent;

private function app(event:FlexEvent):void{

ExternalInterface.addCallback("flex_hello_world",hello_world);

}

private function hello_world(msg:String,str:String):String{

return msg+"-"+str;

}

]]>

</fx:Script>

</s:Application>

插入flash的html文件：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />

<title>使用ExternalInterface调用Flex方法-传参数、有返回值！</title>

<script type="text/javascript" src="swfobject.js"></script>

<script type="text/javascript">

function js_hello_world(){

var obj=document.getElementById('flash');

var msg=obj.flex_hello_world("使用ExternalInterface调用Flex方法","传参数、有返回值");

alert(msg);

}

function js_hello_world2(){

var obj=document.getElementById('flash2');

var msg=obj.flex_hello_world("使用ExternalInterface调用Flex方法","传参数、有返回值");

alert(msg);

}

function js_hello_world3(){

var obj=document.getElementById('flash3');

var msg=obj.flex_hello_world("使用ExternalInterface调用Flex方法","传参数、有返回值");

alert(msg);

}

</script>

</head>

<body>

<input type="button"value="swfobject" width="100"

<div id="flash"></div>

<script type="text/javascript">

swfobject.embedSWF("js4.swf", "flash", "400", "325", "11.1.0", "playerProductInstall.swf", {});

</script>

<input type="button"value="swfobject" width="100"

<embed src="js4.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="400" height="325" id="flash2"></embed>

<input type="button"value="swfobject" width="100"

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="400" height="325" id="flash3">

<param name="movie" value="js4.swf" />

<param name="quality" value="high" />

</object>

</body>

</html>

注：object方式ie以外无法调用Flex方法，embed方式ie无法调用Flex方法
