我需要最近3周的日期范围,包括当前星期的日期范围。
例如:今天的日期是:2018年8月31日
输出将是:
Aug 26 - Sep 01 ,
Aug 19 - Aug 25 ,
Aug 12 - Aug 18
答案 0 :(得分:2)
您可以使用.startOf('week')
查找一周的开始。
var currentWeek = getWeekRange(0);
var lastWeek = getWeekRange(-1);
var weekBeforeLast = getWeekRange(-2);
var currentWeek2 = getWeekRange2(0);
console.log(currentWeek, lastWeek, weekBeforeLast, currentWeek2);
function getWeekRange(week = 0) {
var weekStart = moment().add(week, 'weeks').startOf('week');
return [...Array(7)].map((_, i) =>
weekStart.clone().add(i, 'day').format('DD/MM/YYYY')
);
}
function getWeekRange2(week = 0) {
var weekStart = moment().add(week, 'weeks').startOf('week');
var days = [];
for (var i = 0; i < 7; i++) {
days.push(weekStart.clone().add(i, 'day').format('DD/MM/YYYY'));
}
return days;
}

为澄清起见:
[...Array(7)]
是为了简洁起见。它正在创建一个包含7个Array
项目(即undefined
)的[undefined, undefined, ...]
。这些项目被视为占位符,并将使用.map()
映射到一周中的几天。
尽管是undefined
,但我使用数组中的项目index
来增加星期几-换句话说,数组的第一项[undefined]
将的index
为0
,因此我们将添加0
天,并添加到一周结束。
您还可以执行以下操作:
function getWeekRange(week = 0) {
var weekStart = moment().add(week, 'weeks').startOf('week');
var days = [];
for (var i = 0; i < 7; i++) {
days.push(weekStart.clone().add(i, 'day').format('DD/MM/YYYY'));
}
return days;
}
答案 1 :(得分:0)
尝试一下
moment().range(moment().subtract(3, 'weeks'), moment());
moment().subtract(3, 'weeks') this line will return the time before 3 weeks, moment() will return time now and range() will take the range from those two.
希望它会有所帮助:)
答案 2 :(得分:0)
let startOfWeek = moment().subtract(1, 'weeks').startOf('week').toDate().toISOString();
let endOfWeek = moment().subtract(1, 'weeks').endOf('week').toDate().toISOString();
console.log(startOfWeek, endOfWeek)
