Since XMLHttpRequest ,or the equivalent, object is returned by jQuery, so you can simply use abort function. To cancel ajax requests you have to follow below code.
var myRequest= $.ajax({ type: "POST", url: "file.php", data: "name=you&class=10", success: function(e){ alert( "Awesome : " + e); } }); //Cancel the request myRequest.abort();
That’s it 🙂
