      var day = myDate.getDate(); //日
      var days = myDate.getDay();
      switch (days) {
        case 1:
          days = '星期一';
          break;
        case 2:
          days = '星期二';
          break;
        case 3:

        case 4:
          days = '星期四';
          break;
        case 5:
          days = '星期五';
          break;
        case 6:
          days = '星期六';
          break;
        case 0:
          days = '星期日';
