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)

Expand|Select|Wrap|Line Numbers

 
      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_frame).
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:

Expand|Select|Wrap|Line Numbers

parent.clearInterval(_clear);

Can i use

Expand|Select|Wrap|Line Numbers

parent.window.clearInterval()

And one more thing to accessing global variable it was giving me error
so i have written like

Expand|Select|Wrap|Line Numbers

parent.window.clearInterval(parent.window._clear)

and now it is working .

Thanks a lot ...

of course :) ... just gave it as an example ... even:

Expand|Select|Wrap|Line Numbers

parent.clearInterval(parent._clear);

should have worked ... parent refers to the window already ...

kind regards
