我必须显示每个页面的翻译标题。
我已在subscribe()
中实施了上述代码并添加了翻译,如下所示:
import 'rxjs/add/operator/filter';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/mergeMap';
import { TranslateService } from '@ngx-translate/core';
import { Component, OnInit } from '@angular/core';
import { Router, NavigationEnd, ActivatedRoute } from '@angular/router';
import { Title } from '@angular/platform-browser';
@Component({...})
export class AppComponent implements OnInit {
constructor(
private translate: TranslateService,
private router: Router,
private activatedRoute: ActivatedRoute,
private titleService: Title
) {}
ngOnInit() {
this.router.events
.filter((event) => event instanceof NavigationEnd)
.map(() => this.activatedRoute)
.map((route) => {
while (route.firstChild) route = route.firstChild;
return route;
})
.filter((route) => route.outlet === 'primary')
.mergeMap((route) => route.data)
.subscribe((event) => this.titleService.setTitle(this.translate.instant(event['title']));
}
}
在路由模块中,我将翻译的密钥作为标题传递:
const routes: Routes = [
{ path: 'buildings', component : BuildingsComponent, data : {title : 'BUILDINGS' }}
];
正常情况下工作正常。但是在页面刷新时,它并没有翻译标题。我在页面刷新时收到订阅者event['title']
。
我没有得到如何解决它。 请帮忙。
谢谢:)
