我正在尝试使用子路由进行简单的应用程序.
当我在我的子组件上设置路由时,我收到以下错误消息:
Link "["ChildItem"]" does not resolve to a terminal instruction
如果我将所有路由放在父组件上它可以正常工作.如果我拆分子组件和父组件之间的路由,我会得到上述错误.
这是它在同一组件上的所有路由:
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 })])
以下是单独组件上的路由,在查看Child Compoent时出现错误:
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 })])

这可能对其他用户有用,所以我把它写成aswer,评论可能太短了.
在RouteConfig你的定义ChildItem为父路线.该/...部分使其成为父路线,这意味着它有子女.
@RouteConfig([
// This route is a parent route
{ path: '/child/...', component: ChildItem, as: 'ChildItem' }
])
因此,如果['ChildItem']不指定子路由或不添加路由,则无法简单地路由到useAsDefault: true.
所以你有两个选择:
useAsDefault: true您的一个子路线@RouteConfig([
{ path: '/1', component: SubItem1, as: 'SubItem1', useAsDefault: true},
{ path: '/2/', component: SubItem2, as: 'SubItem2' },
{ path: '/3/', component: SubItem3, as: 'SubItem3' }
])
export class ChildItem{}
使用此选项,每次导航到ChildItem它时,都会立即将您重定向到SubItem1.注意:之前as已弃用alphas,坚持name.
// First way
<a [routerLink]="['/ChildItem', 'SubItem1']">Click Me</a>
// Second way
<a [routerLink]="['/ChildItem/SubItem1']">Click Me</a>
两种方式都相似,但第一种方法可以让您将参数传递给每个路径,例如:
// ChildItem gets "id"
// SubItem1 gets "itemName"
<a [routerLink]="['/ChildItem', {id: 'someId'}, 'SubItem1', {itemName: 'someName'}]">Click Me</a>
// Only SubItem1 gets "id"
<a [routerLink]="['/ChildItem/SubItem1', {id: 'someId'}]">Click Me</a>
我希望这有用而且清楚.
