FF continually working after removing a dynamic hidden iframe

[D Rog]

I use hidden dynamically created iframe to get some additional data from server in JS, so after processing the data I remove the iframe. I noticed that a browser hangs in working state if I remove the iframe. Code looks like:

   
    targetFrame.addEventListener("load", function(){
callback(document.getElementById(targetFrame.id).contentDocument.body.innerHTML);
             document.body.removeChild(document.getElementById(targetFrame.id));
}, false);
 

However not removing iframe can issue accumulating too many iframes and overloading browser resources. Using static hidden frame possible but not desirable. How do you solve the problem? I found some work around but it looks a bit crazy for me, so I want something more reasonable.

IE implementation is a bit different and doesn�t create mentioned problem anyway.

I don't know why you are driving Firefox out of its mind, but why aren't you just using Ajax for this?

What do you mean by Ajax? HTTPXML? I'm trying to avoid using ActiveX for some security reason.

[Bear Bibeault]

Well, the firefox implementation of XHR doesn't use activex. What security problems (besides the fact that it's IE) are you trying to avoid by not using the activex XHR on IE?

[D Rog]

Currently I use 3 browsers Opera, FF, and IE. The last has activex turned off. Certainly underneath implementation of server calling mechanism can use different approaches on different browsers, however I�d like to see it more consistent from esthetical point view.

Anyway, I can live with a work around I found. thank you for your help.
