MomentJS解析大數據字符串

Question

所以，我有這種數據startTime: Fri Dec 28 2018 01:15:00 GMT+0200 (Eastern European Standard Time)和這個endTime: Mon Dec 31 2018 02:15:00 GMT+0200 (Eastern European Standard Time)數據始終采用這種格式。 我需要解析它，這樣我才能在startTime和endTime的時間（在這種情況下為1:15-2:15）的每一天中，在startTime和endTime之間的所有日期中都有一個對象數組。 我有一個答案是

function toDays(startDateString, endDateString) {

  const startDate = moment(startDateString, 'dddd MMM DD YYYY');
  const endDate = moment(endDateString, 'dddd MMM DD YYYY');

  const dates = [];

  while(startDate.isSameOrBefore(endDate, 'day')) {
    let currentDay = startDate.format('dddd');
    dates[currentDay] = [];
    dates[currentDay].push({start:'9:00', end:'18:00'});
    startDate.add(1, 'days');
  }

  return dates;
}

const result = toDays('Mon Dec 24 2018', 'Fri Dec 28 2018');
console.log(result);

但是我不能真正使用它，我不確定如何解決此問題，因為我之前從未使用過。

Answer 1

將天名添加到您創建的新對象中，作為屬性，例如day然后將整個對象推入數組

更改

dates[currentDay] = [];
dates[currentDay].push({start:'9:00', end:'18:00'});

至

dates.push({ day: currentDay, start:'9:00', end:'18:00'})

Answer 2

如果我正確理解了這個問題，那么您可能很難確定如何解析格式startTime: Fri Dec 28 2018 01:15:00 GMT+0200 (Eastern European Standard Time) ？ 如果確實如此，那么我認為以下代碼可能會有所幫助：

<script src='https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.23.0/moment.js'></script>
<script>
function toDays(startDateString, endDateString) {
  const formatString = 'ddd MMM DD YYYY HH:mm:ss [GMT]ZZ [(Eastern European Standard Time)]';
  const startDate = moment(startDateString, formatString).utcOffset("+02:00");
  const endDate = moment(endDateString, formatString).utcOffset("+02:00");
  const start = startDate.format('H:mm');
  const end = endDate.format('H:mm');

  const dates = [];

  while(startDate.isSameOrBefore(endDate, 'day')) {
    let currentDay = startDate.format('dddd');
    dates.push({day: currentDay, start: start, end: end});
    startDate.add(1, 'days');
  }

  return dates;
}

const result = toDays('Fri Dec 28 2018 01:15:00 GMT+0200 (Eastern European Standard Time)', 'Mon Dec 31 2018 02:15:00 GMT+0200 (Eastern European Standard Time)');
console.log(result);
</script>

要點是線const formatString = 'ddd MMM DD YYYY HH:mm:ss [GMT]ZZ [(Eastern European Standard Time)]'; 解析您正確提供的日期格式。
