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:
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 yyyy'}}</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!
