Modify the index.template.html file by adding in the following scripts:

   1:  <script language="JavaScript" type="text/javascript">

   2:  window.onbeforeunload = clean_up;

3:

   4:  function clean_up()

   5:  {

   6:  var flex = document.${application} || window.${application};

   7:  flex.myFlexFunction();

   8:  }

   9:  </script>

Then add following codes in the flex code file:

   1:  import flash.external.ExternalInterface;

2:

   3:  public function cleanUp():void

   4:  {

   5:      fromSwf.close();

   6:  }

.csharpcode, .csharpcode pre{font-size: small;color: black;font-family: consolas, "Courier New", courier, monospace;background-color: #ffffff;/*white-space: pre;*/}.csharpcode pre { margin: 0em; }.csharpcode .rem { color: #008000; }.csharpcode .kwrd { color: #0000ff; }.csharpcode .str { color: #006080; }.csharpcode .op { color: #0000c0; }.csharpcode .preproc { color: #cc6633; }.csharpcode .asp { background-color: #ffff00; }.csharpcode .html { color: #800000; }.csharpcode .attr { color: #ff0000; }.csharpcode .alt {background-color: #f4f4f4;width: 100%;margin: 0em;}.csharpcode .lnum { color: #606060; }.csharpcode, .csharpcode pre{font-size: small;color: black;font-family: consolas, "Courier New", courier, monospace;background-color: #ffffff;/*white-space: pre;*/}.csharpcode pre { margin: 0em; }.csharpcode .rem { color: #008000; }.csharpcode .kwrd { color: #0000ff; }.csharpcode .str { color: #006080; }.csharpcode .op { color: #0000c0; }.csharpcode .preproc { color: #cc6633; }.csharpcode .asp { background-color: #ffff00; }.csharpcode .html { color: #800000; }.csharpcode .attr { color: #ff0000; }.csharpcode .alt {background-color: #f4f4f4;width: 100%;margin: 0em;}.csharpcode .lnum { color: #606060; }

Also add this statements in the initialize function of the flex page, which is usually bind with the initialize property of the Application:

   1:  ExternalInterface.addCallback("myFlexFunction",cleanUp);
