1. When in the beginning of page I have to load specific items that the user have been seen last time
2. When the page was full with ajax call  – and there was also a “submit” button that should send the information (saved already ) that the user have finished entering the fields .

So – jquery have 2 methods: ajaxStart and ajaxStop.

Code:

Put 2 divs on the page :

<div id=”divWait” style=”display:none”> Please wait…</div>

<div id=”divOK” style=”display:none”> All data submitted</div>

And put this on javascript:

$(“#divWait”).ajaxStart(function() {
$(“#divWait”).show();
$(“#divOK”).hide();
});
 $(“#divWait”).ajaxStop(function() {
$(“#divWait”).hide();
$(“#divOK”).show();
});
