ngx-translate不能在ng-bootstrap模式下工作

Question

ngx-translate的translate管道在ng-bootstrap的modal内部不起作用。

<div class="modal-header">
  <h3 class="modal-title">
    {{ 'MODAL.TITLE' | translate }}
  </h3>
</div>

<div class="modal-body">
</div>

<div class="modal-footer">
  <button class="btn btn-primary" type="button" (click)="activeModal.close('Close click')">
    <span class="fa fa-remove"></span> {{ 'BUTTON.CLOSE' | translate }}
  </button>
</div>

Answer 1

在ngx-translate Readme上，写道：

注意：如果您仍然使用Angular <4.3，请使用@ angular / http中的Http和[email protected]。

那有什么区别？

在Angular> = 4.3.x中，您现在需要提供Http，而不是向TranslateModule提供HttpClient：

app.module.ts：

import {HttpClient, HttpClientModule} from "@angular/common/http"; //<-- before import {HttpModule, Http} from "@angular/http";
...
export function HttpLoaderFactory(httpClient: HttpClient) { //<-- before Http
    return new TranslateHttpLoader(httpClient, "i18n/", ".json");
}

@NgModule({
    imports: [
        ...
        HttpClientModule, //<-- before HttpModule
        TranslateModule.forRoot({
          loader: {
            provide: TranslateLoader,
            useFactory: HttpLoaderFactory,
            deps: [HttpClient] //<-- before Http
          }
        })
    ],
    ...
})
