我知道有很多关于这个问题的文章和论坛帖子，其中很多都不起作用并且没有得到解答。有些教程声称他们的代码可以工作，但有些没有下载页面，有些有下载页面，链接不起作用。另外，也许有一种新的方法可以做到这一点，并且我发现的代码不再受支持。

这是我的代码:HTML 和 Javascript

<html>
<head><title>Javascript to SWF</title>
<script language="JavaScript"> 
function getFlashMovie(movieName) {
    var isIE = navigator.appName.indexOf("Microsoft") != -1;
    return (isIE) ? window[movieName] : document[movieName];
}

function callToActionscript() 
{
     getFlashMovie("jscallswf").setMouseXY();
}

callToActionscript();
</script>
</head>
<body style="background:red;">  
<body>
    <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=10,0,0,0" width="450" id="jscallswf" align="middle" data="jscallswf.swf" style="height: 250">
        <param name="allowScriptAccess" value="sameDomain">
        <param name="allowFullScreen" value="false">
        <param name="movie" value="jscallswf.swf">
        <param name="quality" value="High"><param name="bgcolor" value="#ffffff">
        <embed src="jscallswf.swf" quality="High" bgcolor="#ffffff" width="400"     name="jscallswf" align="middle" allowscriptaccess="sameDomain" allowfullscreen="false"     type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer"     style="height: 250">
    </object>
</body>
</body> 
</html>

AS3 代码:

import flash.external.ExternalInterface;

ExternalInterface.addCallback("setMouseXY", rotateCam);
function rotateCam()
{
    td.text = "NEWTEXT";
}

这是另一种 Javascript 方法:

<html>
<head><title>Javascript to SWF</title>
<style type="text/css">
#jscallswf {
margin:300px;
}
</style>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.min.js">    </script>
<script type="text/javascript" src="swfobject.js"></script>
<script language="JavaScript"> 
// JS Code
// Embedding through SWFObject rocks in comparison with Adobe's garbage:

var flashvars = {};

var params                  =   {};
params.menu                 =   "false";
params.salign               =   "t";
params.scale                =   "noscale";
params.wmode                =   "transparent";
params.allowScriptAccess    =   "always";

var attributes              =   {};
attributes.id = "jscallswf";

swfobject.embedSWF("jscallswf.swf", "flashDiv", "274", "246", "9.0.0", "", flashvars, params, attributes);

// Functions needed for calling Flex ExternalInterface
function thisMovie(movieName) 
{
    if (navigator.appName.indexOf("Microsoft") != -1) 
    {
        return window[movieName];
    } 
    else 
    {
        return document[movieName];
    }
}

function callFlashMethod()
{
    thisMovie("jscallswf").setMouseXY();
}


$(document).ready(function(){
    callFlashMethod();
});
</script>
</head>
<body style="background:red;">  
<body>
<div id="flashDiv" style="margin:200px;"></div>
</body>
</body> 
</html>

两者都在控制台中返回错误“Uncaught TypeError:无法调用未定义的方法'setMouseXY'”

最佳答案

请尝试以下操作:

Main.as

            //info("ei_invokeFunction(p_sMethod:String=" + p_sMethod + ", ...args=[" + args + "]):void");
            switch (p_sMethod) 
            {
                case "func1":
                    func1.apply(this, args);

            }
        }

        private function init(e:Event = null):void

你可以尝试运行这个并让我知道你的输出，我已经在 FF27 上进行了测试
