Question

我在Angular 2中遇到router.parent.navigate问题。而且我不知道这是Angular的问题还是我的代码有问题。
当我有父组件App.ts时，其内容配置为路由并托管所有视图。

, ROUTER_BINDINGS, RouterLink, RouterOutlet, Route,
LocationStrategy, HashLocationStrategy} from 'angular2/router';

import { BusinessNameLookup } from './BusinessNameLookup/BusinessNameLookup.ts';
import { ABN } from './ABN/ABN.ts';
import { LookupDetails } from './LookupDetails/LookupDetails.ts';
import { Businessnames } from './BusinessNames/BusinessNames.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)]);

在我写这篇文章时，我将导航到主页并在<router-outlet>属性中查看它。不，我一直在放this.router.parent.navigate(['/ABN']);

这行我把它放入按钮调用的功能中。问题开始我按下这个按钮我已导航到另一页面，然后再返回到主页并在URL中显示问号符号 http://localhost:5000/?它也会消失。

Answer 1

当处理导航事件的<button>位于<form>元素

内时，这似乎是一个问题

例如：

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

此模板将刷新页面并在URL中添加问号符号

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

此模板将正常工作并按预期路由。

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

Answer 2

导航后只返回false。

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