Is there any way to get that time in javascript?

Answer 1

Take note of the time before the request and after the request. The difference will be the time taken to complete the request.

var start = new Date().getTime(),
    difference;

$.ajax({
    url: url,
    type: "POST",
    data: {
        name: "John",
        location: "Boston"
    }
}).done(function () {
    difference = new Date().getTime() - start;
});
