我在EditListingComponent的html中有一個後退按鈕,我想連接到列表組件。下面的作品,如果我連接到列表組件 返回使用routerlink的後退按鈕沒有鏈接到所需的頁面
然而,當我想回去的具體商家與ID($鍵),它不工作...返回
的FOLL是路線:
const appRoutes: Routes = [
{path:'', component:HomeComponent},
{path: 'listings', component:ListingsComponent},
{path: 'listing/:id', component:ListingComponent},
{path: 'edit-listing/:id', component:EditListingComponent},
{path: 'add-listing', component:AddListingComponent}
]
的FOLL是我的編輯列表組件的HTML:
<a [routerLink]="['/listing/'+listing.$key]">Back</a> <!--why does this routerlink does not work - ['/listing/'+listing.$key]-->
<br />
<h2 class="page-header">Edit Checklist</h2>
<form (submit)="onEditSubmit()">
<div class="form-group">
<label>Checklist</label>
<textarea class="form-control" type="text" [(ngModel)]="checklist" name="checklist" required></textarea>
</div>
<div class="form-group">
<label>Notes</label>
<textarea class="form-control" type="text" [(ngModel)]="notes" name="notes" required></textarea>
</div>
<input type="submit" value="submit" class="btn btn-success">
</form>
編輯listing.component.ts文件的代碼是FOL低點...
export class EditListingComponent implements OnInit {
id:any;
checklist:any; /*ngmodel binds the html fields to the properties in the component*/
notes:any;
constructor(private firebaseService: FirebaseService, private router:Router, private route:ActivatedRoute) { }
ngOnInit() {
// Get ID
this.id = this.route.snapshot.params['id'];
this.firebaseService.getListingDetails(this.id).subscribe(listing => {
this.checklist = listing.checklist;
this.notes = listing.notes;
console.log(listing);
});
}
onEditSubmit(){
let listing = {
checklist: this.checklist,
notes: this.notes
}
this.firebaseService.updateListing(this.id, listing).then(() => {
this.router.navigate(['/listing/'+this.id]);
});
}
}
你能請一些線索見解,爲什麼這可能是..我有機會獲得上市堂妹的$ key屬性我看到了我的console.log
謝謝。是的工作..但即時通訊仍然好奇,爲什麼葉無法正常工作:'Back'因爲即時通訊使用列表。$鍵在其他組件沒有任何問題。 – Nosail
你是什麼意思,它不工作?你得到一個錯誤或什麼? –
