問題與Router.Parent.Navigate（）

我正面臨一個問題router.parent.navigate在Angular 2. 而且我不知道這是Angular問題還是我的代碼有問題。
當我有父組件App.ts其中內容配置路由和主機的所有意見。問題與Router.Parent.Navigate（）

import {bootstrap, Component, View, bind, Inject} from 'angular2/angular2'; 
import { 
ROUTER_DIRECTIVES, 
ROUTER_PROVIDERS, 
RouteConfig 
, ROUTER_BINDINGS, RouterLink, RouterOutlet, Route, 
LocationStrategy, HashLocationStrategy} from 'angular2/router'; 

/* Importing Application Components */ 
import { BusinessNameLookup } from './BusinessNameLookup/BusinessNameLookup.ts';

import { BusinessModel } from './DataModels/BusinessModel.ts'; 

@Component({ 
    selector: 'app' 
}) 

@View({ 
     template: `<router-outlet></router-outlet>`, 
     directives: [RouterOutlet, RouterLink, ROUTER_DIRECTIVES] 
}) 

@RouteConfig([ 
     new Route({ path: '/', component: BusinessNameLookup }), 
     new Route({ path: '/ABN', component: ABN, name: 'ABN' }), 
     new Route({ path: '/LookupDetails', component: LookupDetails, name: 'LookupDetails' }), 
     new Route({ path: '/BusinessNames', component: Businessnames, name: 'BusinessNames' }), 
     new Route({ path: '/BusinessWebAddress', component: BusinessWebAddress, name: 'BusinessWebAddress' }), 
     new Route({ path: '/BusinessCategory', component: BusinessCategory, name: 'BusinessCategory' }), 
     new Route({ path: '/ContactInformations', component: ContactInformations, name: 'ContactInformations' }), 
     new Route({ path: '/BusinessPurchaseAddress', component: BusinessPurchaseAddress, name: 'BusinessPurchaseAddress' }), 
     new Route({ path: '/BusinessImages', component: BusinessImages, name: 'BusinessImages' }), 
     new Route({ path: '/SurveyQuery', component: SurveyQuery, name: 'SurveyQuery' }) 
]) 

class AppComponent { 
} 

bootstrap(AppComponent, [ROUTER_BINDINGS, bind(LocationStrategy).toClass(HashLocationStrategy)]);

當我寫它時，會導航到主頁並在<router-outlet>屬性中查看它。不，我一直把this.router.parent.navigate(['/ABN']);

這行我把它放到按鈕調用的函數。問題開始欺騙我按下這個按鈕，我已經瀏覽到，而另一個頁面，然後再返回到主頁並顯示問號在URL http://localhost:5000/?其也消失也。

這似乎是一個問題時處理導航事件<button>位於<form>元素

內部。例如：

//Component function 
gotoAnotherRoute() { 
    this._router.navigate(['/another-route']); 
}

此模板將刷新頁面，並添加一個問號在URL中

<form> 
    <input [(ngModel)]="model.name"/> 
    <button (click)="gotoAnotherRoute()">Validate</button> 
</form>

此模板將按預期正常工作和路由。

<form> 
    <input [(ngModel)]="model.name"/> 
</form> 
<button (click)="gotoAnotherRoute()">Validate</button>

這是一個真正的錯誤嗎？或者這種行爲總之有意義。謝謝。 – Johannes

不確定它是否是一個真正的錯誤，因爲HTML表單的標準行爲是通過「submit」類型的輸入來提交的，或者如果沒有提交類型的話，表單中的第一個按鈕將被提交... –

導航後只返回false。

//Component function 
gotoAnotherRoute() { 
    this._router.navigate(['/another-route']); 
    return false; 
}
