Problem with IE and setInterval() not refreshing/updating

rated 0 times [ 122] [ 1] / answers: 1 / hits: 15712 / 14 Years ago, fri, august 6, 2010, 12:00:00

I'm using JavaScript/Jquery to make a page auto-update with a value from a database, although it doesn't seem to update in Internet Explorer. It works fine in FireFox & Chrome. Can anyone explain what's wrong? It looks like IE is just displaying a cached version of the page. How can I prevent this happening? Thanks.

function updateComm() {  

 var url=commandSys.php;  

 jQuery(#theElement).load(url);  

}



setInterval(updateComm(), 1000);

Try disabling the cache with ajaxSetup

$.ajaxSetup ({

    // Disable caching of AJAX responses */

    cache: false

});



function updateComm() {  

 var url=commandSys.php;  

 jQuery(#theElement).load(url);  

}



setInterval(updateComm, 1000);

Alternatively, you can manually just append a +new Date to url so it appends a query string to prevent caching.

Alternatively, disable caching on the server-side.
