Luxon js从星期几中获取日期

Question

Moment 可以选择根据周数（0 到 6）获取日期名称。我看到 luxon 有星期几，从 1 到 7 的数字（星期一是 1，星期日是 7）https://moment.github.io/luxon/#/parsing但我不知道如何转换星期数字到日期名称？

瞬间

moment().day(0).format('ddddd'); // Sunday

Answer 1

我会看一下 luxon 的Info.weekdays，这将给出各种格式的日期名称。

然而，日期编号与 Moment 略有不同，因此您必须进行翻译。

const { Info } = luxon;
// moment.js days of week: Sunday: 0 -> Monday: 6
const momentDays = [0,1,2,3,4,5,6];

console.log('Index', 'Long', 'Short');
momentDays.forEach(day => {
    // Luxon day indexes are Monday: 0 -> Sunday 6
    const luxonDay = (day + 6) % 7;
    console.log(day, Info.weekdays('long')[luxonDay], Info.weekdays('short')[luxonDay]);
})

.as-console-wrapper { max-height: 100% !important; top: 0; }
