javascript location href not working on jquery ajax post -

i have following issue: make jquery ajax post and, on success, need change location of browser index view. javascript:

$.post(createreleasenotificationurl, notifications_form.serialize(), function (response) {             if (response.indexof("error") == 0) {                 $("#newnotification_createstatus").html(response);             }             else {                 window.location.assign('@url.action("index")');                 //window.location = window.location;                                }                       })         .fail(function () {                             $("#newnotification_createstatus").html("an error has occured.<br /> please contact system administrator<br /> if problem persists.");         }); 

however, nothing happens !! missing ?

ps: tried using location.href, no avail.

check this:

window.location.href = '@url.action("index", "controllername")';
