IE / Firefox query

[woolyg]

Hi all,

 

Just a quick query regarding the way that IE (specifically 7) handles AJAX calls.

 

I'm using a standard getData call to get info from an external PHP file. It displays fine.

However, if any changes are made to the external PHP file (say, I changed an image on it for display purposes) and I click on the link to call the AJAX in IE, the original image is shown, not the new one.

 

If I do the same thing in Firefox, the new image displays without needing to open a new browser window and 'refresh' the AJAX.

 

Has anyone else had this problem?

Is there an easy fix to make IE show the most up-to-date info in a PHP call?

 

This is really messing with my cross-browser compatibility stuff...!

 

Cheers,

WoolyG

No basically, you can do that, somewhere you have to fix it, i made a real time mobile voip application. which contain FF, IE, Opera, worked fine, but you need to deep debug.

 

*document.getElementById , and check your <div id="names" >
