Маршрутизация в Angular2 - ссылка «['Name']» не преобразуется в инструкцию терминала
Я пытаюсь получить простое приложение, работающее с дочерней маршрутизацией.
Когда я настраиваю маршруты на моем дочернем компоненте, я получаю следующее сообщение об ошибке:
Link "["ChildItem"]" does not resolve to a terminal instruction
Если я размещу все маршруты в родительском компоненте, он будет работать правильно. Если я разделю маршруты между дочерним и родительским компонентами, я получу вышеуказанную ошибку.
Вот это работает со всеми маршрутами на одном компоненте:
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 })])
Вот маршруты на отдельных компонентах, где я получаю ошибку при просмотре дочернего компонента:
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>
`
})
@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],
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' }
])
export class AppComponent {}
bootstrap(AppComponent, [ROUTER_PROVIDERS, provide(LocationStrategy, { useClass: HashLocationStrategy })])
