仅将日期与 luxon Datetime 进行比较

Question

我有两个 luxon 对象，

let startDate = DateTime.fromISO(startDate)
let someDate = DateTime.fromISO(someDate)

我如何比较 someDate 是否 <= startDate，只有日期，没有时间？

Answer 1

文档： https: //moment.github.io/luxon/#/math? id=comparing-datetimes

var DateTime = luxon.DateTime;

var d1 = DateTime.fromISO('2017-04-30');
var d2 = DateTime.fromISO('2017-04-01');

console.log(d2 < d1); //=> true
console.log(d2 > d1); //=> false

<script src="https://moment.github.io/luxon/global/luxon.min.js"></script>

Answer 2

要仅比较日期，请使用 startOf

startDate.startOf("day") <= someDate.startOf("day")
