在我的应用程序中,我曾使用路由器展示了三个组件。

export const routing = RouterModule.forRoot([
   { path: '', component: HomeListComponent },
   { path: 'badge', component: BadgeListComponent},
   { path: 'badge-form', component: BadgeFormComponent },
   { path: 'badge-form/:id', component: BadgeFormComponent }
]);


因为当我转到表单时,我想在URL中使用类似这样的/badge/badge-form而不是/badge-form,所以将路由配置更改为:

{ path: '', component: HomeListComponent },
{
    path: 'badge',
    component: BadgeListComponent,
    children: [
        { path: 'badge-form', component: BadgeFormComponent },
        { path: 'badge-form/:id', component: BadgeFormComponent }
    ]
}


不幸的是,它无法正常工作,我无法找到原因,即使我进入BadgeListComponent网址,它也总是加载/badge/badge-form

BadgeListComponent的HTML代码:

<div class="material-card-wide mdl-card mdl-shadow--2dp">
  <div class="mdl-card__title mdl-card--border">
    <h2 class="mdl-card__title-text">{{ title }}</h2>
  </div>
  <div class="list-card-body">
    <table class="data-table-format">
      <thead>
        <tr>
          <th>badgeNumber</th>
          <th>authorizationLevel</th>
          <th>endOfValidity</th>
          <th></th>
        </tr>
      </thead>
      <tbody>
        <tr *ngFor="let badge of pagedItems" (click)="editBadge(badge.badge_badgeNumber)">
          <th>{{ badge.badge_badgeNumber }}</th>
          <th>{{ badge.badge_authorizationLevel }}</th>
          <th>{{ badge.badge_endOfValidity }}</th>
          <td width="5%" (click)="deleteConfirmation(badge.badge_badgeNumber); $event.stopPropagation();">
            <i class="material-icons delete-data-icon">delete_forever</i>
          </td>
        </tr>
      </tbody>
    </table>
  </div>

  <!-- pager -->
  <div class="mdl-paging" *ngIf="pager.pages && pager.pages.length">
    <button [disabled]="pager.currentPage === 1"
      class="mdl-button mdl-js-button mdl-js-ripple-effect mdl-button--icon"
      (click)="setPage(pager.currentPage - 1)">
      <i class="material-icons">keyboard_arrow_left</i>
    </button>
    <a *ngFor="let page of pager.pages"
      [class.selected]="pager.currentPage === page"
      class="mdl-button mdl-js-button mdl-js-ripple-effect mdl-button--icon"
      (click)="setPage(page)">
      {{ page }}
    </a>
    <button [disabled]="pager.currentPage === pager.totalPages"
      class="mdl-button mdl-js-button mdl-js-ripple-effect mdl-button--icon"
      (click)="setPage(pager.currentPage + 1)">
      <i class="material-icons">keyboard_arrow_right</i>
    </button>
    <br />
    <span class="paginationStats">Pages {{ pager.startPage }}-{{ this.pager.endPage }} of {{ pager.totalPages }}</span>
  </div>
  <div class="mdl-card__actions mdl-card--border">
    <div class="buttonHolder">
      <button routerLink="../badge-form" class="mdl-button mdl-js-button mdl-js-ripple-effect mdl-button--primary" *ngIf="!editing">
        Add
      </button>
    </div>
  </div>
</div>


javascript - Angular 4 child 路由器未加载-LMLPHP

最佳答案

导航到/badge/badge-form时,当前配置告诉Angular Router通过匹配BadgeListComponent渲染/badge,然后在BadgeFormComponentBadgeListComponent中渲染<router-outlet>

您需要无组件路线仅渲染子代。

{ path: '', component: HomeListComponent },
{
    path: 'badge',
    children: [
        { path: '', component: BadgeListComponent },
        { path: 'badge-form', component: BadgeFormComponent },
        { path: 'badge-form/:id', component: BadgeFormComponent }
    ]
}
