queue sync or async function. You can put sleep between the functions

queue.js

function queue() {
    var i = 0,
        arr = arguments;
    (function next() {
        var args = arguments;
        if (i < arr.length) {
            var func = arr[i++];
            var funcArgs = [].concat(next, [].slice.call(args));
            if (!isNaN(func)) setTimeout(function () {
                arr[i++].apply(this, funcArgs)
            }, func);
            else {
                func.apply(this, funcArgs);
            }
        }
    })();
}

queue(
    function (next) {
        $.ajax(document.location.href, {
            success: function (data, textStatus, jqXHR) {
                next(data, textStatus, jqXHR);
            }
        });
    },
    function (next, data, textStatus, jqXHR) {
        // do stuff after the jquery ajax call and get the params pass to the "next" callback in the previous function
        next();
    },
    500, //sleep
    function (next) {
        // do stuff after 500ms
    });
