如何使用moment.js获取从当前月份到过去一个月的所有月份的列表

由 oalias发布于 2020-05-30 15:24:05

I'm trying to generate a list of months starting from April 2020 to a month in the past ( October 2019 ) using moment.js.

const start = moment().startOf('month')
const startMonth = moment('10-01-2018', 'MM-DD-YYYY').format('MMMM YYYY')
const month = moment().startOf('month').format('MM')
for (let i = 0; i < month; i++) {
  const m = start.subtract(1, 'month').format('MMMM YYYY')
  if (m === startMonth) {
    break;
  }
  console.log(m)
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.26.0/moment.min.js" integrity="sha256-5oApc/wMda1ntIEK4qoWJ4YItnV4fBHMwywunj8gPqc=" crossorigin="anonymous"></script>

结果我只有5个月的时间。谁能帮忙吗？

像这样吗

const start = moment().startOf('month')
const end = moment('10-01-2018', 'MM-DD-YYYY')

let results = []
let current = start
while (current.format('MMMM YYYY') !== end.format('MMMM YYYY')) {
  results.push(current.format('MMMM YYYY'))
  current = current.subtract(1, 'month')
}
// need to add current one last time because the loop will have ended when it is equal to the end date, and will not have added it
results.push(current.format('MMMM YYYY'))

console.log(results)

Using isSameOrBefore()

const start = moment().startOf('month')
const end = moment('11-11-2019', 'MM-DD-YYYY')

while (end.isSameOrBefore(start, 'month')) {
  console.log(start.format('MMMM YYYY'))
  start.subtract(1, 'month')
}
