如何自定义 date.now 格式? [英] How to customize date.now format?

问题描述

.ts

currentDate = Date.now();

.html

{{ currentDate |日期 }}

如何显示时间而不是 2019 年 10 月 25 日我想要这样:

<块引用>

在 {{October}} {{2019}} 的 {{25th}} 天签署了吗?

有人已经实现了自定义时间格式吗?

解决方案

您可以为您的日期后缀实现一个自定义管道，并从角度 date 管道中获取其余部分.

import { Pipe, PipeTransform } from '@angular/core';@Pipe({ name: 'dateSuffix' })导出类 DateSuffixPipe 实现 PipeTransform {转换(日期:日期):字符串 {让天 = date.getDay();让后缀='th';如果(天 == 1 || 天 == 21 || 天 == 31){后缀 = 'st';}如果(天 == 2 || 天 == 22){后缀 = 'nd';}如果(天 == 3 || 天 == 23){后缀 = 'rd';}返回后缀；}}

HTML

签署此 {{currentDate |日期:'dd'}}{{currentDate |{{currentDate | dateSuffix}} 天日期:'LLLL y​​yyy'}}</div>

不要忘记将您的自定义管道添加到模块声明中！

.ts

currentDate = Date.now();

.html

{{ currentDate | date }}

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

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

Anyone there already implemented custom time format?

解决方案

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>

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