I tried to call a flash callback method from JavaScript.
But it seems not working.
The flash action script example code is like below [Simplified]:

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"; 
}

The javascript example code is written below [Simplified]:

 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();
 });

It is always display the error in fire bug console “flashFile.js_method_to_call is not a function”.

    Here’s something that should work really good:

    1. Use SWFObject.js for embedding the Flash content:

      // 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);

    2. Use this for the HTML:

      <body>
    <div id="flashDiv"></div>
</body>

    3. To call your Flash method use this pattern:

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

    4. Call the Flash method:

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