Spinner.js

var Spin = {
    spinner: {},
    startSpin: function (option) {
        var settings = $.extend({
            element: 'formBody'
        }, option);

        var target = document.getElementById(settings.element);
        var spinner = new Spinner().spin(target);
        this.spinner = spinner;
    },
    stopSpin: function () {
        if (typeof (this.spinner) != "undefined" && this.spinner !== null && typeof (this.spinner.opts) == "object") {
            this.spinner.stop();
        }
    }
};

Created methods to use spin.js more effectively.
