JavaScript、vue、uniapp如何获取本周开始时间和结束时间？

		//获得本周的开始时间：
		getStartDayOfWeek(time) {
			let now = new Date(time); // 当前日期
			let nowDayOfWeek = now.getDay(); // 今天本周的第几天
			let day = nowDayOfWeek || 7;
			let nowDay = now.getDate(); // 当前日
			let nowMonth = now.getMonth(); // 当前月
			return this.formatDate(new Date(now.getFullYear(), nowMonth, nowDay + 1 - day));
		},
		//获得本周的结束时间：
		getEndDayOfWeek(time) {
			let now = new Date(time); // 当前日期
			let nowDayOfWeek = now.getDay(); // 今天本周的第几天
			let day = nowDayOfWeek || 7;
			let nowDay = now.getDate(); // 当前日
			let nowMonth = now.getMonth(); // 当前月
			return this.formatDate(new Date(now.getFullYear(), nowMonth, nowDay + 7 - day));
		},
		// 日期格式化
		formatDate(date) {
			let myyear = date.getFullYear();
			let mymonth = date.getMonth() + 1;
			let myweekday = date.getDate();
			if (mymonth < 10) {
				mymonth = '0' + mymonth;
			}
			if (myweekday < 10) {
				myweekday = '0' + myweekday;
			}
			return (myyear + '-' + mymonth + '-' + myweekday);
		}
