封装倒计时 arguments妙用

    var cout = {
        init:function (classname) {
            var $this = this
            if (classname) {
                var classname = classname

            $(document).delegate(classname, "click", function () {
                var to_time = new Date(Date.parse($(this).text()))
                $this.pri(this, to_time)
            })
        },
