圆形moment.js对象时间到最近的30分钟间隔 [英] Round moment.js object time to nearest 30 minute interval

问题描述

我试图绕过这一刻。时间对象到下一个最近的30分钟间隔。但看起来我的逻辑错了。有人能帮我吗。
Ex：

I was trying to round the moment.js time object to next nearest 30 minute interval. But looks my logic us wrong. Can someone help me. Ex:

10:13am -> 10:30am
11:45am -> 12:00pm

这是我目前的代码

start = moment();
minuteReminder = start.minute() % 30;
start.add(minuteReminder, 'minutes');
start.format("D YYYY, h:mm:ss a");

推荐答案

const start = moment('2018-12-08 09:42');
const remainder = 30 - (start.minute() % 30);
 
const dateTime = moment(start).add(remainder, "minutes").format("DD.MM.YYYY, h:mm:ss a");

console.log(dateTime);
