javascript - 使用 momentjs 或 Date() 获取 3 月份的 2020-02-29T00 :00:00. 000Z

Question

我正在尝试获取当月的开始和结束日期，但对于三月份，它给我的开始日期为 2020-02-29T00:00:00.000Z

使用momentjs

    var firstDay = new moment().startOf('month').utcOffset(0);
    firstDay.set({hour:0,minute:0,second:0,millisecond:0});
    var lastDay = new moment().endOf('month').utcOffset(0);
    lastDay.set({hour:23,minute:59,second:59,millisecond:0})

使用日期()

    var date = new Date(),
        y = date.getFullYear(),
        m = date.getMonth();
    var firstDay = new Date(y, m, 1);
    var lastDay = new Date(y, m + 1, 1);

如何解决这个问题？

Answer 1

尝试 startOf/endOf 后跟 utcOffset()

Note: startOf - set to the first of this month, 12:00 am

var firstDay = new moment('2020-02-29T00:00:00.000Z').utcOffset(0).startOf('month');
console.log(firstDay.format())

var lastDay = new moment('2020-02-29T00:00:00.000Z').utcOffset(0).endOf('month');
console.log(lastDay.format())
