ajax - Javascript requests -

i have 2 checkboxes on selection of each 1 raise ajax request in order response server. need call method once when there atleast 2 seconds gap after last request made. idea? means not want call methods when checkboxes clicked continously less 2 seconds gap. how can cancel request made if time gap between requests in less 2 seconds. note want method fired once after last request not followed other requests 2 seconds.

var timeout;  cleartimeout(timeout);  timeout = settimeout(function () { // call method }, 2000);  

note wan excecute method once last request made.

you don't show code, assuming have function doajax() ajax request, can ensure isn't called until 2 seconds after last click in 2 second period using settimeout() function this:

var timerid; document.getelementbyid("yourcheckboxidhere").onclick = function() {     cleartimeout(timerid);     timerid = settimeout(doajax, 2000); }; 

note doajax not have parentheses after when passed parameter settimeout() function.

if need pass parameters doajax() function change line settimeout() to:

    timerid = settimeout(function(){        doajax(parameters, go, here);     }, 2000);
