问题与Router.Parent.Navigate（）

我正面临一个问题router.parent.navigate在Angular 2. 而且我不知道这是Angular问题还是我的代码有问题。
当我有父组件App.ts其中内容配置路由和主机的所有意见。问题与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 { ABN } from './ABN/ABN.ts';

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

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)]);

当我写它时，会导航到主页并在<router-outlet>属性中查看它。不，我一直把this.router.parent.navigate(['/ABN']);

这行我把它放到按钮调用的函数。问题开始欺骗我按下这个按钮，我已经浏览到，而另一个页面，然后再返回到主页并显示问号在URL http://localhost:5000/?其也消失也。

这似乎是一个问题时处理导航事件<button>位于<form>元素

内部。例如：

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

此模板将刷新页面，并添加一个问号在URL中

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

此模板将按预期正常工作和路由。

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

这是一个真正的错误吗？或者这种行为总之有意义。谢谢。 – Johannes

不确定它是否是一个真正的错误，因为HTML表单的标准行为是通过“submit”类型的输入来提交的，或者如果没有提交类型的话，表单中的第一个按钮将被提交... –

导航后只返回false。

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