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: `
Child Item
    

    
SubItem1
    
SubItem2
    
SubItem3
    
    `
})  
export class ChildItem{}


@Component({
    selector: 'home',
    directives: [COMMON_DIRECTIVES, CORE_DIRECTIVES, ROUTER_DIRECTIVES, RouterLink],
    template: `
Home page
    Click Me`
})
export class Home{}


@Component({
  selector: 'my-app',
  template: `
Routing Test
  `,
  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: `
Child Item
    

    
SubItem1
    
SubItem2
    
SubItem3
    
    `
})
@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: `
Home page
    Click Me`
})
export class Home{}


@Component({
  selector: 'my-app',
  template: `
Routing Test
  `,
  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' }
])

@RouteConfig([
        { path: '/1', component: SubItem1, as: 'SubItem1', useAsDefault: true},
        { path: '/2/', component: SubItem2, as: 'SubItem2' },
        { path: '/3/', component: SubItem3, as: 'SubItem3' }
])
export class ChildItem{}

// First way
Click Me

// Second way
Click Me

// ChildItem gets "id"
// SubItem1 gets "itemName"
Click Me

// Only SubItem1 gets "id"
Click Me

@RouteConfig([
        // This route is a parent route
        { path: '/child/...', component: ChildItem, as: 'ChildItem' }
])

@RouteConfig([
        { path: '/1', component: SubItem1, as: 'SubItem1', useAsDefault: true},
        { path: '/2/', component: SubItem2, as: 'SubItem2' },
        { path: '/3/', component: SubItem3, as: 'SubItem3' }
])
export class ChildItem{}

// First way
Click Me

// Second way
Click Me

// ChildItem gets "id"
// SubItem1 gets "itemName"
Click Me

// Only SubItem1 gets "id"
Click Me
