    clearInterval() : iframe & window communication problem

    Dear all,
    I have given snippet of code in that it is cgi file in which i am using iframe , source of iframe is calling another cgi file.
    JavaScript / DHTML / AJAX Syntax (Toggle Plain Text)
    Code:
          this is ABC.cgi file
      <script type="text/javascript">
      function interval_setting(){ _clear = 5; _clear =  setInterval("xmlhttpPost11('index.cgi','tracker_shower','Latest_frame','Tracker_loader',_clear,'','','')",20000);}
      </script>
   
      <body bgcolor="#FFFFFF"onLoad='interval_setting();'>
      <td bgcolor="#ffffff" height="75">
         <div id = "Tracker_loader" align = 'center' style = "display:none"><img src='/images/ajax-loader.gif'></div>
 
        <iframe id= "Latest_frame" src="bidsupdate.cgi?TYPE=$type" scrolling="no" frameborder="0" height=100% width=100%>
        </iframe>
      </td>

this is ABC.cgi file <script type="text/javascript"> function interval_setting(){ _clear = 5; _clear = setInterval("xmlhttpPost11('index.cgi','tracker_shower','Latest_frame','Tracker_loader',_clear,'','','')",20000);} </script> <body bgcolor="#FFFFFF"onLoad='interval_setting();'> <td bgcolor="#ffffff" height="75"> <div id = "Tracker_loader" align = 'center' style = "display:none"><img src='/images/ajax-loader.gif'></div> <iframe id= "Latest_frame" src="bidsupdate.cgi?TYPE=$type" scrolling="no" frameborder="0" height=100% width=100%> </iframe> </td>
    now setInterval function calling xmlhttpPost11() that function is actually a ajax function which is Reloading this iframe(Latest_f rame).
    now in bidsupdate.cgi i met a condition where i need to stop this setInterval()
    but how i can do that ....
    can i write some code in bidsupdate.cgi file to clearInterval But how ....

    waiting for reply
    thanks in advance

      basically you would need to clear the interval in the parent frame/window ... so from you iframe-source you would need to do something like:

      Code:
      parent.clearInterval(_clear);

          Can i use
          Code:
          parent.window.clearInterval()
          And one more thing to accessing global variable it was giving me error
          so i have written like
          Code:
          parent.window.clearInterval(parent.window._clear)
          and now it is working .

          Thanks a lot ...

              of course :) ... just gave it as an example ... even:
              Code:
              parent.clearInterval(parent._clear);
              should have worked ... parent refers to the window already ...

              kind regards
