  getDay() 返回星期，返回的是0-6的数字，0 表示星期天。（这句话在“返回星期方法”一开始就有）。

  接下来看代码。

  今天是星期天，那么var mynum=getDay()返回的是阿拉伯数字“0”，数组定义var weekday=["星期日","星期一","星期二","星期三","星期四","星期五","星期六"]，weekday[0]就是数组的第一个元素“星期日”。

  ok，讲完了。

  var time = new Date();

  var week = time.getDay();

  var weekDay;

  switch (week) {

                       case 0:

                       weekDay = "星期天";

                       break;

                       case 1:

                       weekDay = "星期一";

                       break;

                       case 2:

                       weekDay = "星期二";

                       break;

                       case 3:

                       weekDay = "星期三";

                       break;

                       case 4:

                       weekDay = "星期四";

                       break;

                       case 5:

                       weekDay = "星期五";

                       break;

                       case 6:

                       weekDay = "星期六";

                       break;

  }

  写一个数组 week=arr[星期7，星期1，星期2，星期3，星期4，星期5，星期6]；var w=date.getDay();week[w]就是星期天
