前言

本文将介绍在 Angular4 项目中配置 ngx-translate i18n 国际化组件的相关内容，分享出来供大家参考学习，下面来一起看看详细的介绍：

npm 安装 ngx-translate 模块

rush:bash;"> npm install @ngx-translate/core --save npm install @ngx-translate/http-loader --save

在 Angular 项目配置

app.module.ts

rush:js;"> import { TranslateLoader,TranslateModule} from '@ngx-translate/core'; import { TranslateHttpLoader } from '@ngx-translate/http-loader';

imports: [
TranslateModule.forRoot({
loader: {
provide: TranslateLoader,useFactory: (createTranslateHttpLoader),deps: [Http]
}
})
]

结果如下：

rush:js;"> import { browserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { HttpModule,Http } from '@angular/http'; import { TranslateLoader,TranslateModule} from '@ngx-translate/core'; import { TranslateHttpLoader } from '@ngx-translate/http-loader';

import { AppComponent } from './app.component';

export function createTranslateHttpLoader(http: Http) {
return new TranslateHttpLoader(http,'./assets/i18n/','.json');
}

@NgModule({
declarations: [
AppComponent
],imports: [
browserModule,HttpModule,TranslateModule.forRoot({
loader: {
provide: TranslateLoader,deps: [Http]
}
})
],providers: [],bootstrap: [AppComponent]
})
export class AppModule { }

app.component.ts

添加

rush:js;"> import { TranslateService } from "@ngx-translate/core";

constructor(public translateService: TranslateService) {

}

ngOnInit() {
// --- set i18n begin ---
this.translateService.addLangs(["zh","en"]);
this.translateService.setDefaultLang("zh");
const browserLang = this.translateService.getbrowserLang();
this.translateService.use(browserLang.match(/zh|en/) ? browserLang : 'zh');
// --- set i18n end ---
}

结果如下：

rush:js;"> import { Component } from '@angular/core'; import { TranslateService } from "@ngx-translate/core";

@Component({
selector: 'app-root',templateUrl: './app.component.html',styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'app';

constructor(public translateService: TranslateService) {

}
