Ich versuche, eine einfache App mit Child-Routing arbeiten.Routing in Angular2 - Link "['Name']" löst nicht zu einer Terminalanweisung
Wenn ich Setup die Routen auf mein Kind Komponente ich die folgende Fehlermeldung:
Link "["ChildItem"]" does not resolve to a terminal instruction
Wenn ich alle Routen auf der übergeordneten Komponente legen Sie es richtig funktioniert. Wenn ich die Routen zwischen den Kind- und Elternkomponenten teile, erhalte ich den obigen Fehler.
Hier ist es mit allen Routen auf der gleichen Komponente arbeiten:
import {bootstrap} from 'angular2/platform/browser';
import {Component, provide} from 'angular2/core';
import {COMMON_DIRECTIVES, CORE_DIRECTIVES, FORM_DIRECTIVES, NgFor, NgIf} from 'angular2/common';
import {ROUTER_DIRECTIVES, ROUTER_PROVIDERS, RouteConfig, RouterLink, RouterOutlet, Route, LocationStrategy, HashLocationStrategy} from 'angular2/router';
@Component({selector: 'subItem1',template: `SubItem1`})export class SubItem1{}
@Component({selector: 'subItem2',template: `SubItem2`})export class SubItem2{}
@Component({selector: 'subItem3',template: `SubItem3`})export class SubItem3{}
@Component({
selector: 'childItem',
directives: [COMMON_DIRECTIVES, CORE_DIRECTIVES, ROUTER_DIRECTIVES, RouterLink],
template: `<h2>Child Item</h2>
<ul>
<li><a [routerLink]="['/SubItem1']">SubItem1</a></li>
<li><a [routerLink]="['/SubItem2']">SubItem2</a></li>
<li><a [routerLink]="['/SubItem3']">SubItem3</a></li>
</ul>
`
})
export class ChildItem{}
@Component({
selector: 'home',
directives: [COMMON_DIRECTIVES, CORE_DIRECTIVES, ROUTER_DIRECTIVES, RouterLink],
template: `<h2>Home page</h2>
<a [routerLink]="['/ChildItem']">Click Me</a>`
})
export class Home{}
@Component({
selector: 'my-app',
template: `<h1>Routing Test</h1>
<router-outlet></router-outlet>`,
directives: [ROUTER_DIRECTIVES, RouterLink, RouterOutlet]
})
@RouteConfig([
{ path: '/', component: Home, as: 'Home' },
{ path: '/child', component: ChildItem, as: 'ChildItem' },
{ path: '/child/1/', component: SubItem1, as: 'SubItem1' },
{ path: '/child/2/', component: SubItem2, as: 'SubItem2' },
{ path: '/child/3/', component: SubItem3, as: 'SubItem3' }
])
export class AppComponent {}
bootstrap(AppComponent, [ROUTER_PROVIDERS, provide(LocationStrategy, { useClass: HashLocationStrategy })])
Hier werden die Routen auf separaten Komponenten ist, wo ich den Fehler, wenn das Kind compoent viewing:
import {bootstrap} from 'angular2/platform/browser';
import {Component, provide} from 'angular2/core';
import {COMMON_DIRECTIVES, CORE_DIRECTIVES, FORM_DIRECTIVES, NgFor, NgIf} from 'angular2/common';

@Component({selector: 'subItem1',template: `SubItem1`})export class SubItem1{}
@Component({selector: 'subItem2',template: `SubItem2`})export class SubItem2{}
@Component({selector: 'subItem3',template: `SubItem3`})export class SubItem3{}
@Component({
selector: 'childItem',
directives: [COMMON_DIRECTIVES, CORE_DIRECTIVES, ROUTER_DIRECTIVES, RouterLink],
template: `<h2>Child Item</h2>
<ul>
<li><a [routerLink]="['/SubItem1']">SubItem1</a></li>
<li><a [routerLink]="['/SubItem2']">SubItem2</a></li>
<li><a [routerLink]="['/SubItem3']">SubItem3</a></li>
</ul>
`
})
@RouteConfig([
{ path: '/1', component: SubItem1, as: 'SubItem1' },
{ path: '/2/', component: SubItem2, as: 'SubItem2' },
{ path: '/3/', component: SubItem3, as: 'SubItem3' }
])
export class ChildItem{}
@Component({
selector: 'home',
directives: [COMMON_DIRECTIVES, CORE_DIRECTIVES, ROUTER_DIRECTIVES, RouterLink],

})
export class Home{}

directives: [ROUTER_DIRECTIVES, RouterLink, RouterOutlet]
})
@RouteConfig([

export class AppComponent {}

Der Fehler ist ziemlich klar. Sie erstellen einen Link zur Route des Elternteils, zu welchem Kind wird es gehen?Sie können dies lösen, indem Sie in Ihrem Link angeben, welches Kind gehen soll, oder einfach "useAsDefault: true" in einem Ihrer Kinder hinzufügen. –
