微信小程序横向日期控件

图片上这样

首先说思路，上面的日期是循环出来显示的，我设置的是七天

OK 放代码 先wxml

{{timeItem.time}}

然后JS

function getThisMonthDays(year, month) {
      return new Date(year, month, 0).getDate();
    }
    // 计算每月第一天是星期几
    function getFirstDayOfWeek(year, month) {
      return new Date(Date.UTC(year, month - 1, 1)).getDay();
    }
    const date = new Date();
    const cur_year = date.getFullYear();
    const cur_month = date.getMonth() + 1;
    const cur_date = date.getDate();
    const weeks_ch = ['日', '一', '二', '三', '四', '五', '六'];
    //利用构造函数创建对象
    function calendar(date, week) {
      this.date = cur_year + '-' + cur_month + '-' + date;
      if (date == cur_date) {
        this.week = "今天";
      } else if (date == cur_date + 1) {
        this.week = "明天";
      } else {
        this.week = '星期' + week;
      }
    }
    //当前月份的天数
    var monthLength = getThisMonthDays(cur_year, cur_month)
    //当前月份的第一天是星期几
    var week = getFirstDayOfWeek(cur_year, cur_month)
    var x = week;
    for (var i = 1; i <= monthLength; i++) {
      //当循环完一周后，初始化再次循环
      if (x > 6) {
        x = 0;
      }
      //利用构造函数创建对象
      that.data.calendar[i] = new calendar(i, [weeks_ch[x]][0])
      x++;
    }
    //限制要渲染的日历数据天数为7天以内
    var flag = that.data.calendar.splice(cur_date, that.data.calendar.length - cur_date <= 7 ? that.data.calendar.length : 7)
    that.setData({
      calendar: flag
    })
}
