如何从javascript调用flash actionscript回调方法？

Tri*_*Sam 5 javascript flash jquery swfobject actionscript-3

我试图从JavaScript调用flash回调方法.但它似乎不起作用.flash动作脚本示例代码如下[简化]:

import flash.events.ActivityEvent; 
import flash.events.StatusEvent; 
import flash.external.ExternalInterface;

var test_var = ExternalInterface.addCallback("js_method_to_call", flash_method);


function flash_method()
{   
  return "test"; 
}

javascript示例代码写在[简化]下面:

 function callFlashMethod(){
   var flashFile = eval("window.document.test");
   flashFile.js_method_to_call;
 }
 function loadTest(){
   swfobject.embedSWF("test.swf", "test", "1", "1", "10.0.0", false);
 }

 $(document).ready(function(){
   loadTest();
   callFlashMethod();
 });

它总是在火灾控制台"flashFile.js_method_to_call不是函数"中显示错误.

这里的东西应该非常好用:

使用SWFObject.js嵌入Flash内容:

// Embedding through SWFObject rocks in comparison with Adobe shits:
var flashvars = {};

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

var attributes              =   {};
attributes.id = "${swf}";

swfobject.embedSWF("${swf}.swf", "flashDiv", "${width}", "${height}", "9.0.0", "", flashvars, params, attributes);

将此用于HTML:
```
<body>
    <div id="flashDiv"></div>
</body>
```

要调用Flash方法,请使用以下模式:

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

调用Flash方法:

function callFlashMethod()
{
    thisMovie("${swf}").js_method_to_call();
}

您将获得对嵌入式SWF对象的引用,并使用它来调用您的as3方法.

//AS3 Code
ExternalInterface.addCallback("helloFromJS",helloFromJS);

private function helloFromJS():void
{
    trace("JS is saying hello");
}


//HTML Code
<object width="100%" height="100%" id="Test">
          <param name="movie" value="Test.swf"/>

//JS Code
var swfObject = document.getElementById("Test");
swfObject.helloFromJS();
