js如何开发去签到功能？如何使用Jquery实现每日签到功能

一直想做一个签到功能，但是百度了都没有自己想要的，所以就借着网上搜到的素材然后整合自己之前写的插件layerModel自己整合了一个，大家娱乐娱乐就好！

calendar.js

var calUtil = {
    getDaysInmonth : function(iMonth, iYear){
      var dPrevDate = new Date(iYear, iMonth, 0);
      return dPrevDate.getDate();
    },
    bulidCal : function(iYear, iMonth) {
      var aMonth = new Array();
      aMonth[0] = new Array(7);
      aMonth[1] = new Array(7);
      aMonth[2] = new Array(7);
      aMonth[3] = new Array(7);
      aMonth[4] = new Array(7);
      aMonth[5] = new Array(7);
      aMonth[6] = new Array(7);
      var dCalDate = new Date(iYear, iMonth - 1, 1);
      var iDayOfFirst = dCalDate.getDay();
      var iDaysInMonth = calUtil.getDaysInmonth(iMonth, iYear);
      var iVarDate = 1;
      var d, w;
      aMonth[0][0] = "日";
      aMonth[0][1] = "一";
