JS如何根据当前日期获取一周所有日期

function getWeekDataList(data) {
	//根据日期获取本周周一~周日的年-月-日
	var weekList = [];
	var date = new Date(data);
	//判断本日期是否为周日，获取本周一日期
	if(date.getDay()=="0"){
		date.setDate(date.getDate() -6);
	}else {
		date.setDate(date.getDate() - date.getDay() + 1);
	}
	var myDate=date.getDate();
	var myMonth=date.getMonth() + 1;
	if(date.getDate()<10){
		myDate= '0'+ myDate;
	}
	if(date.getMonth() + 1<10){
		myMonth='0'+myMonth;
	}
	weekList.push(date.getFullYear() + "-" + myMonth+ "-" + myDate);
	// 获取周二以后日期
	for(var i=0;i<6;i++) {
		date.setDate(date.getDate() + 1);
		myDate=date.getDate();
		myMonth=date.getMonth() + 1;
		if(date.getDate()<10){
			myDate= '0'+ myDate;
		}
		if(date.getMonth() + 1<10){
			myMonth='0'+myMonth;
		}
		weekList.push(date.getFullYear() + "-" + myMonth+ "-" +myDate);
	}
	console.log(weekList);
	return weekList
}

// 获取当前一周的时间
    getWeekTime() {
      let that = this;
      this.userForm.TimeChoose = [];
      var currentFirstDate;
      var formatDate = function(date) {
        var year = date.getFullYear() + "-";
        var month = date.getMonth() + 1 + "-";
        var day = date.getDate() + "";
        return year + month + day;
      };
      var addDate = function(date, n) {
        date.setDate(date.getDate() + n);
        return date;
      };
      var setDate = function(date) {
        var week = date.getDay() - 1;
        date = addDate(date, week * -1);
        currentFirstDate = new Date(date);
        var arr = [];
        for (var i = 0; i < 7; i++) {
          var a = formatDate(i == 0 ? date : addDate(date, 1)); //星期一开始
          arr.push(a);
        }
        return arr;
      };
      setDate(new Date());
      var num = 0; //num为0时表示当前周，递增或递减时周数也递增或递减
      let setWeek = setDate(addDate(currentFirstDate, 7 * num));
      this.userForm.TimeChoose = setWeek;
    },
