Since AJAX load method uses jQuery get method internally, So that you may get cached data.
To remove this this error make sure to send a unique key as part of the query string and it will give you the new content /result /uncached data from server.
A simple ajax function
function unassign_shop(full_id)
{
var n=full_id.length;
var id=full_id.substr(9,n-9);
var commentContainer = $("div#unassigned_" + id).parent();
var str = 'remove_shop=removed&salesman_id=' + <?php echo $salesman_id; ?> + '&assign_id=' + id ;
commentContainer.slideUp('slow', function() {$("div#assigned_" + id).remove();});
document.getElementById("unassigned").innerHTML="<img src='../design/content/loading.gif' title='loading' />";
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("unassigned").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","ajax/fetch_unassigned.php?"+str,true);
xmlhttp.send();
}
If you use some functions like above then you will get only the cached data because the query string is same as in most cases.
var str = 'remove_shop=removed&salesman_id=' + <?php echo $salesman_id; ?> + '&assign_id=' + id ;
One solution is to pass timestamp value as part of the query string so that it will generate a unique request.
