我想检查当前时间是否在 11:00 和 moment.js 之前。我怎样才能做到这一点？

Question

我正在使用 moment.js 库，如果我想检查当前时间是否小于 11:00 我该如何实现？

let  todaysDate = moment() // "yyyy-mm-dd"
var time = "22:59";  // set condition to just before 11:00
var elevenOclockTimeCheck = moment(todaysDate).startOf(time); 
 
// check to see if time is equal or greater to 11:00 PM
console.log(elevenOclockTimeCheck);

// If it is before 11:00 then execte if block
                
if (todaysDate < elevenOclockTimeCheck) {

}

Answer 1

您可以使用以下代码：

moment().isBefore(moment({ hour:11, minute: 0}));

Answer 2

请注意，您不需要moment.js为此 - 直接的 js 日期/时间操作将完成它。

const todaysDate = new Date();
const hours = todaysDate.getHours();
const isBefore11 = hours <= 11;
const result = `The time ${isBefore11 ? 'is' : 'is not'} before 11`;

console.log(result);
// my current time is 11:02pm (23:02)- so this consoles 'The time is not before 11'

Answer 3

只需调用 .hour getter 并比较

moment().hour() < 11;
