显然,Angular2的beta比新的更新,所以没有太多的信息,但我试图做我认为是一些相当基本的路由。
使用快速启动代码和来自https://angular.io网站的其他片段进行攻击,导致了以下文件结构:
angular-testapp/ app/ app.component.ts boot.ts routing-test.component.ts index.html
随着文件被填充如下:
index.html
<html> <head> <base href="/"> <title>Angular 2 QuickStart</title> <link href="../css/bootstrap.css" rel="stylesheet"> <!-- 1. Load libraries --> <script src="node_modules/angular2/bundles/angular2-polyfills.js"></script> <script src="node_modules/systemjs/dist/system.src.js"></script> <script src="node_modules/rxjs/bundles/Rx.js"></script> <script src="node_modules/angular2/bundles/angular2.dev.js"></script> <script src="node_modules/angular2/bundles/router.dev.js"></script> <!-- 2. Configure SystemJS --> <script> System.config({ packages: { app: { format: 'register',defaultExtension: 'js' } } }); System.import('app/boot') .then(null,console.error.bind(console)); </script> </head> <!-- 3. Display the application --> <body> <my-app>Loading...</my-app> </body> </html>
boot.ts
import {bootstrap} from 'angular2/platform/browser' import {ROUTER_PROVIDERS} from 'angular2/router'; import {AppComponent} from './app.component' bootstrap(AppComponent,[ ROUTER_PROVIDERS ]);
app.component.ts
import {Component} from 'angular2/core'; import {RouteConfig,ROUTER_DIRECTIVES,ROUTER_PROVIDERS,LocationStrategy,HashLocationStrategy} from 'angular2/router'; import {RoutingTestComponent} from './routing-test.component'; @Component({ selector: 'my-app',template: ` <h1>Component Router</h1> <a [routerLink]="['RoutingTest']">Routing Test</a> <router-outlet></router-outlet> ` }) @RouteConfig([ {path:'/routing-test',name: 'RoutingTest',component: RoutingTestComponent,useAsDefault: true},]) export class AppComponent { }
routing-test.component.ts
import {Component} from 'angular2/core'; import {Router} from 'angular2/router'; @Component({ template: ` <h2>Routing Test</h2> <p>Interesting stuff goes here!</p> ` }) export class RoutingTestComponent { }
EXCEPTION: Template parse errors: Can't bind to 'routerLink' since it isn't a known native property (" <h1>Component Router</h1> <a [ERROR ->][routerLink]="['RoutingTest']">Routing Test</a> <router-outlet></router-outlet> "): AppComponent@2:11
我在这里发现了一个模糊的相关问题; router-link directives broken after upgrading to angular2.0.0-beta.0.然而,答案之一的“工作示例”基于预beta代码 – 这仍然可以工作,但我想知道为什么我创建的代码不工作。
任何指针都会感谢!

< = RC.1 您的代码缺失
@Component({ ... directives: [ROUTER_DIRECTIVES],...)}
您不能使用诸如routerLink或router-outlet的指令,而不让它们为您的组件所知。
虽然指令名称在Angular2中更改为区分大小写,但元素仍然使用 – 以像< router-outlet>以便与需要以自定义元素名称的web组件规范兼容。

要使ROUTER_DIRECTIVES全局可用,请将此提供程序添加到bootstrap(…):
provide(PLATFORM_DIRECTIVES,{useValue: [ROUTER_DIRECTIVES],multi: true})
则不再需要向每个组件添加ROUTER_DIRECTIVES。
