Question

我有两个luxon对象

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

如果someDate是<= startDate，只有日期而不是时间，我该如何比较？

Answer 1

要仅比较日期，请使用<?xml version="1.0" encoding="UTF-8"?> <UserStoreManager class="com.wso2.custom.usermgt.CustomUserStoreManager"> <Property name="url">jdbc:mysql://localhost:3306/wso2</Property> <Property name="userName">root</Property> <Property encrypted="true" name="password">subhash123</Property> <Property name="driverName">com.mysql.jdbc.Driver</Property> <Property name="ReadGroups">true</Property> .......................................

startOf

Answer 2

使用x = [1, 2] x.append([3, 4]) # gives [1, 2, [3, 4]] x.extend([3, 4]) # gives [1, 2, 3, 4]来获取年份中的整数，请参见https://moment.github.io/luxon/docs/class/src/datetime.js~DateTime.html#instance-get-ordinal

ordinal

Answer 3

这两个答案都不适合leap年。我在以下方面找到了成功，

function dateTimesAreSameDay(dateTime1, dateTime2) {
  return dateTime1.month === dateTime2.month && dateTime1.day === dateTime2.day;
}

Answer 4

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

仅将日期与luxon日期时间进行比较
