Angular 角度子路径观测器
在Angular5应用程序中,我的路由定义如下:Angular 角度子路径观测器,angular,angular5,angular-routing,Angular,Angular5,Angular Routing,在Angular5应用程序中,我的路由定义如下: path: 'my-object/:id', component: MyObjectDetailComponent, children: [ {path: '', redirectTo: 'sublist', pathMatch: 'full'}, {path: 'sublist', component: PointComponent}, {path: 'new', componen
path: 'my-object/:id',
component: MyObjectDetailComponent,
children: [
{path: '', redirectTo: 'sublist', pathMatch: 'full'},
{path: 'sublist', component: PointComponent},
{path: 'new', component: PointFormComponent},
],
在MyObjectDetailComponent模板文件中,我有:
<button #new />
<router-outlet></router-outlet>
当我向用户显示PointForm时,我需要隐藏一些界面对象(如new button)
我相信我需要在url或路由中添加一些观察者,但不知道如何(以及在哪里)做到这一点
当用户输入PointFormComponent(路径:new)时,它应该隐藏
(和一些其他UI元素),并在用户离开时再次显示这些元素。您可以在MyObjectDetailComponent中添加类似的内容:
import { Router } from '@angular/router';
export class MyObjectDetailComponent implements OnInit {
currentUrl: string;
constructor(private router:Router) { }
ngOnInit() {
// that´s how you get the current url
currentUrl = this.router.url;
}
}
并在模板中添加类似的内容
<button *ngIf="currentUrl == ![add path to "new" url here]" #new />
<router-outlet></router-outlet>
您需要这样做,这意味着您需要检查路由更改,如果更改的路由中包含新路由,则将hideflag设置为true并隐藏contorls
class MyClass {
hideInputs = false;
constructor(private router: Router) {
router.events.subscribe((val) => {
const href = window.location.href;
this.hideInputs = href.endsWith('/new');
});
}
}
<button *ngIf="hideInputs " #new />
class-MyClass{
hideInputs=false;
构造函数(专用路由器:路由器){
router.events.subscribe((val)=>{
const href=window.location.href;
this.hideInputs=href.endsWith('/new');
});
}
}
所以当urlhttp://domain//new
?是的,它确实是:“domain/object/:id/new”尝试一下我的答案可能对您有效这不起作用,因为我切换子路由时不会触发OnInit。工作非常完美,非常简单:)我刚刚更改了includes('new')
的href.endsWith('/new'))
和'hideInputs'用于编辑@Robert-好的,这基本上是个好概念,订阅路由事件并执行活动
