.ts

currentDate = Date.now();

.html

{{ currentDate | date }}

我该如何显示时间而不是2019年10月25日:

How can I display the time instead of Oct 25, 2019 I want it this way:

在{{October}} {{2019}}的{{25th}}天签名了吗?

Signed this {{25th}} day of {{October}} {{2019}}?

有人在实施自定义时间格式吗?

Anyone there already implemented custom time format?

推荐答案

您可以为日期后缀实现自定义管道，并从有角的date管道中获取其余管道.

You can implement a custom pipe for your date suffix and take the rest from the angular date pipe.

import { Pipe, PipeTransform } from '@angular/core'; @Pipe({ name: 'dateSuffix' }) export class DateSuffixPipe implements PipeTransform { transform(date: Date): string { let day = date.getDay(); let suffix = 'th'; if (day == 1 || day == 21 || day == 31) { suffix = 'st'; } if (day == 2 || day == 22) { suffix = 'nd'; } if (day == 3 || day == 23) { suffix = 'rd'; } return suffix; } }

HTML

<div> Signed this {{currentDate | date:'dd'}}{{currentDate | dateSuffix}} day of {{currentDate | date:'LLLL yyyy'}} </div>

别忘了将自定义管道添加到模块声明中！

Don't forget to add your custom pipe to module declarations!
