Angular2 beta14 Typescript routerLink绑定错误

Question

我试图用Angular2的路由器创建一个向导。 Angular2建议有一个主引导文件，它将引导所有的应用程序组件。由于我无法做SPA，我希望每个页面都能引导它自己的组件。

我得到routerLink以下错误，当我运行应用程序：

“EXCEPTION：模板解析错误： 不能绑定到‘routerLink’，因为它不是一个已知的原生属性（”对于= “#Wizard of Wizards”[selected] =“SelectedWizard == wizard”[value] =“wizard.name”[ERROR - >] [routerLink] =“''+ wizard.path +''”> {{wizard。名}} “

这是我的页面组件：

/// <reference path="angular2/typings/browser.d.ts" /> 
/// <reference path="angular2/core.d.ts" /> 
/// <reference path="angular2/router.d.ts" /> 

import {bootstrap} from 'angular2/platform/browser'; 
import {Component} from 'angular2/core'; 
import {ROUTER_PROVIDERS} from 'angular2/router'; 

import {Wizard1} from './wizard1'; 
import {Wizard2} from './wizard2'; 
import {Step1} from './step1'; 
import {Step2} from './step2'; 
import {Step3} from './step3'; 
import {Step4} from './step4'; 
import {Step5} from './step5'; 

@Component({ 
    selector: 'page', 
    template: 
'<div> 
    <select (change)="setSelectedWizard($event.target.value)"> 
     <option *ngFor="#wizard of Wizards" [selected]="SelectedWizard == wizard" [value]="wizard.name" [routerLink]="'' + wizard.path + ''">{{wizard.name}}</option> 
    </select> 
    <wizard1> 
     <step1> 
      <h1>First!</h1> 
     </step1> 
     <step2> 
      <h1>Second!</h1> 
     </step2> 
     <step3> 
      <h1>Third!</h1> 
     </step3> 
     <step4> 
      <h1>Fourth!</h1> 
     </step4> 
     <nav> 
      <button type="button" value="Next" [class]="(SelectedStepIndex == Steps.length) ? 'btn btn-primary hidden' : 'btn btn-default'" (click)="next()" [routerLink]="['' + Steps[SelectedStepIndex] + '']">Next</button> 
     </nav> 
     <router-outlet></router-outlet> 
    </wizard1> 
    <wizard2> 
     <step1> 
      <h1>First!</h1> 
     </step1> 
     <step5> 
      <h1>Fifth!</h1> 
     </step5> 
     <nav> 
      <button type="button" value="Next" [class]="(SelectedStepIndex == Steps.length) ? 'btn btn-primary hidden' : 'btn btn-default'" (click)="next()" [routerLink]="['' + Steps[SelectedStepIndex] + '']">Next</button> 
     </nav> 
     <router-outlet></router-outlet> 
    </wizard2> 
    <router-outlet></router-outlet> 
</div>' 
}) 
export class Page { 
    Wizards = [{name: 'wizard1', path:'/wizard1'}, {name: 'wizard2', path: '/wizard2'}]; 
    SelectedWizard = this.Wizards[0]; 

    setSelectedWizard(value) { 
     this.SelectedWizard = value; 
    } 
} 

bootstrap(Page, [ROUTER_PROVIDERS]); 
bootstrap(Wizard1, [ROUTER_PROVIDERS]); 
bootstrap(Wizard2, [ROUTER_PROVIDERS]); 
bootstrap(Step1); 
bootstrap(Step2); 
bootstrap(Step3); 
bootstrap(Step4); 
bootstrap(Step5); 

Wizard1

/// <reference path="angular2/core.d.ts" /> 
/// <reference path="angular2/router.d.ts" /> 

import {Component} from 'angular2/core'; 
import {RouteConfig, ROUTER_PROVIDERS} from 'angular2/router'; 

@RouteConfig([ 
    { path: '/wizard1', name: 'wizard1', component: Wizard1 } 
]) 
@Component({ 
    selector: 'wizard1', 
    template:`<div><ng-content></ng-content></div>` 
}) 
export class Wizard1 { 
    Steps = ['/Step1', '/Step2', '/Step3', '/Step4']; 
    SelectedStepIndex = 0; 

    next() { 
     ++this.SelectedStepIndex; 
    } 
} 

Wizard2

/// <reference path="angular2/core.d.ts" /> 
/// <reference path="angular2/router.d.ts" /> 

import {Component} from 'angular2/core'; 
import {RouteConfig, ROUTER_PROVIDERS} from 'angular2/router'; 

@RouteConfig([ 
    { path: '/wizard2', name: 'wizard2', component: Wizard2 } 
]) 
@Component({ 
    selector: 'wizard2', 
    template:`<div><ng-content></ng-content></div>` 
}) 
export class Wizard2 { 
    Steps = ['/Step1', '/Step5']; 
    SelectedStepIndex = 0; 

    next() { 
     ++this.SelectedStepIndex; 
    } 
} 

所有步骤都与此类似，在自己的.ts文件

/// <reference path="angular2/core.d.ts" /> 
/// <reference path="angular2/router.d.ts" /> 

import {Component} from 'angular2/core'; 
import {RouteConfig} from 'angular2/router'; 

@RouteConfig([ 
    { path: '/Step1', name: 'Step1', component: Step1 } 
]) 
@Component({ 
    selector: 'step1', 
    template: `<div><ng-content></ng-content></div>` 
}) 
export class Step1 { 

} 

这是怎么回事？为什么这不起作用？

环境

1. 的Visual Studio 2015年更新1
2. ASP.NET 5和6 MVC
3. DNX 4.5.1和5.0
4. Angular2打字稿

Answer 1

添加ROUTER_DIRECTIVES到您的组件供应商：

@Component({directives: [ROUTER_DIRECTIVES]}) 

Answer 2

你是缺少ROUTER_DIRECTIVES缺少导入Page组件&指令选项ComponentMetaData，这就是角度不理解的原因routerLink & routerOutlet指令在页面上。请包括下列线

import {ROUTER_PROVIDERS, ROUTER_DIRECTIVES} from 'angular2/router'; 

那么很明显在注入该组件directives选项

@Component({ 
    selector: 'page', 
    //.... 
    //other options 
    //.... 
    directives: [ROUTER_DIRECTIVES] 
}) 

我不知道你为什么这样做bootstrap您的应用程序多次ROUTER_DIRECTIVES？理想情况下，应该只有一个main-component，其他组件将是它的孩子。
