Angular 5-日期-语言

问题描述

我在Angular 5应用程序中使用此表达式:

I use this expression in my Angular 5 application:

{{ viewDate | date:'MMM' }}

月份缩写用英语显示.如何将输出切换为德语?

The month abbreviation is shown in English. How do I switch the output to German?

推荐答案

正如您在编辑中指出的那样，您必须在应用程序中定义语言环境. DatePipe 状态的文档

As you pointed in your edit out already you have to define a locale within your app. The documentation for the DatePipe states

必须像这样使用管道

{{ date_expression | date[:format[:timezone[:locale]]] }}

如您所见，管道接受format，timezone和locale参数(除了要解析的实际日期).进一步阅读文档说明

As you can see, the pipe accepts a format, timezone and locale parameter (besides the actual date that is to be parsed).Reading further, documentation states

此处是.您可能希望将整个应用程序本地化为德语.首先，您要在AppModule中导入德语语言环境.

Here's a read up on how the LOCALE definition works.You probably want to localize your entire application in German.First, you want to import the German locales within your AppModule.

import { registerLocaleData } from '@angular/common';
import localeDe from '@angular/common/locales/de';

registerLocaleData(localeDe);

现在您可以照常使用语言环境

Now you can use the locale as usual

@NgModule({
  // ...
  providers: [{provide: LOCALE_ID, useValue: 'de'}]
})
export class AppModule{}

您的初始表达式{{viewDate | date:'MMM'}}现在应该输出德语本地化的缩写月份.

Your initial expression {{viewDate | date:'MMM'}} should now output the german localized abbreviated month.
