我試圖通過使用路由器服務來更改頁面標題。但是,變量總是無法從路由器服務獲取值。誰能幫忙?謝謝!使用Angular 2路由器服務更改頁面標題
vtc.route.ts
const routes: Routes = [
{
path: '', component: VtcComponent, children: [
{ path: '', redirectTo: "step1", pathMatch: "full" },
{ path: 'step1', component: Step1Component, data:{pageHeader: 'Step1'} },
{ path: 'step2', component: Step2Component, data:{pageHeader: 'Step2'} },
......
]
}
];
vtc.component.ts
export class VtcComponent implements OnInit {
private subscription: Subscription;
private subscription1: Subscription;
webLinkParameter: string;
brokerInformation: IBroker;
authInfo: IAuth;
pageHeader: string;
constructor(private dataService: VtcDataService, private brokerService: BrokerService, private activatedRoute: ActivatedRoute, private authService: AuthService) { }
ngOnInit() {
this.subscription = this.activatedRoute.queryParams.subscribe(
(param: any) => {
this.webLinkParameter = param['brokerid'];
});
//This is the part that the variable trying to get value from router service
this.subscription1 = this.activatedRoute.data.subscribe(res => {this.pageHeader = res['pageHeader']});
console.log("pageHeader: " + this.pageHeader);
....
}
變量pageHeader始終顯示在控制檯輸出,這意味着它沒有從路由器服務的任何價值可言「不確定」。我在這裏錯過了什麼嗎?謝謝!
謝謝您的建議!我們決定使用PageService來解決我們的問題,並且它現在可以工作。 –
