angular 多语言

1.安装依赖

npm install @ngx-translate/core --save

npm install @ngx-translate/http-loader --save

 

2.引入模块

在app.module.ts中引入

import { HttpClientModule, HttpClient } from '@angular/common/http';

import { TranslateModule, TranslateLoader } from '@ngx-translate/core'; import { TranslateHttpLoader } from '@ngx-translate/http-loader';



export function HttpLoaderFactory(httpClient: HttpClient) {

　　　　return new TranslateHttpLoader(httpClient);

　　}

 

@ngmodule导入

imports: [

TranslateModule.forRoot({

loader: {

provide: TranslateLoader,

useFactory: HttpLoaderFactory,

deps: [HttpClient]

}

})

]

 

3.添加多语言文件

assets/i18n/en.json

{"welcome":"WELCOME"}

assets/i18n/zh.json

{"welcome":"欢迎"}

 

4.初始化语言

在app.component.ts添加语言初始化，默认为浏览器语言

import { TranslateService } from '@ngx-translate/core';



constructor(public translate: TranslateService) {

translate.addLangs(["zh", "en"]);

translate.setDefaultLang('zh');



const browserLang = translate.getbrowserLang();

//修改语言

translate.use(browserLang.match(/zh|en/) ? browserLang : 'zh');

}

 

5.使用

{{”welcome“|translate}}
