前端获取当前一周时间 数组形式

 getWeek () {
      var getWeek = (function () {
        // 一周
        var arr = [];  // 周一开始
        var newdate = new Date();
        var now = newdate.getTime();
        var day = newdate.getDay();    // 星期
        var oneDayTime = 60 * 60 * 24 * 1000;
        for (var i = 1; i < 8; i++) {
          if (day >= i) {
            var dd = new Date(now - (day - i) * oneDayTime).getDate();
            arr.push(dd < 10 ? '0' + dd : dd + '');
          } else {
            var aa = new Date(now + (i - day) * oneDayTime).getDate();
            arr.push(aa < 10 ? '0' + aa : aa + '');
          }
        }
        return arr
      })();
　　console.log(this.getWeek)
      this.getWeek = getWeek
    },
