Question

我有一个包含以下路线的项目：

{ path: '', component: GamesListingComponent },

    { path: 'inicio', component: HomeComponent },

    { path: 'listar',
        children: [
            { path: '', component: HomeComponent },
            { path: 'fabricantes', component: ManufacturesListingComponent },
            { path: 'plataformas', component: PlatformsListingComponent },
            { path: 'usuarios', component: UsersListingComponent },
            { path: 'jogos', component: GamesListingComponent },
            { path: '**', component: HomeComponent }
        ]
    },

    { path: 'cadastrar',
        children: [
            { path: '', component: HomeComponent },
            { path: 'fabricantes', component: ManufacturesRegisterComponent },
            { path: 'plataformas', component: PlatformsRegisterComponent },
            { path: 'usuarios', component: UsersRegisterComponent },
            { path: 'jogos', component: GamesRegisterComponent },
            { path: '**', component: HomeComponent }
        ]
    },

    { path: '**', component: GamesListingComponent }

我希望routerLinkActive只能通过子路由的名称启用，例如：

访问＆＃34; / listar / jogos＆＃34;和＆＃34; / cadastrar / jogos＆＃34;，想要访问这两个路由，同一个routerLinkActive是活动的。

了header.html

<div class="jumbotron">
    <p class="text-center title"><a [routerLink]="['/inicio']">Lightning Games</a></p>
    <p class="text-center">A sua loja de jogos desde o seu primeiro dia</p>
</div>
<nav class="navbar navbar-toggleable-md navbar-inverse bg-inverse">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarText">
        <ul class="navbar-nav mr-auto">
            <li class="nav-item" [routerLinkActive]="['active']">
                <a class="nav-link" [routerLink]="['/inicio']">Início <span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item" [routerLinkActive]="['active']">
                <a class="nav-link" [routerLink]="['/listar', 'plataformas']">Plataformas</a>
            </li>
            <li class="nav-item" [routerLinkActive]="['active']">
                <a class="nav-link" [routerLink]="['/listar', 'fabricantes']">Fabricantes</a>
            </li>
            <li class="nav-item" [routerLinkActive]="['active']">
                <a class="nav-link" [routerLink]="['/listar', 'usuarios']">Usuários</a>
            </li>
            <li class="nav-item" [routerLinkActive]="['active']">
                <a class="nav-link" [routerLink]="['/listar', 'jogos']">Jogos</a>
            </li>
        </ul>
    </div>
</nav>

Answer 1

如果您希望自己的路线在 ONE EXACT ROUTE

添加[routerLinkActiveOptions]="{exact:true}"将使活动类仅适用于精确路由匹配。

如果这是您想要的，请按以下步骤更新您的<li>代码：

<li class="nav-item" [routerLinkActive]="['active']" [routerLinkActiveOptions]="{exact:true}">
   <a class="nav-link" [routerLink]="['/inicio']">Início <span class="sr-only">(current)</span></a>
</li>

如果您希望多条相似路线的路线链接

查看我从一个官方Angular路由示例中修改过的这个Plunkr代码。 https://plnkr.co/edit/wWyVfxDHbSA8tYcpsNsF?p=preview

注意两件事：

在app-routing.module.ts中，您会看到有两条相似的路线：

{ path: 'heroes/:id', component: HeroDetailComponent }, { path: 'heroes', component: HeroesComponent }

在app.component.ts中（在嵌入式模板代码中），您会看到它们是一条路线：

<routerLink="/heroes" routerLinkActive="active">Heroes</a>

此路由与app-routing.module.ts中设置的路径的两个匹配 - 这意味着它将为以 / heroes

<强>更新

在您的示例中，您可以通过将路由更改为以下内容来执行此操作：

app.routes.ts

const appRoutes: Routes = [

  { path: '', component: GamesListingComponent },

  { path: 'inicio', component: HomeComponent },

  { path: '', component: HomeComponent },

  { path: 'jogos', component: GamesListingComponent },
  { path: 'fabricantes', component: ManufacturesListingComponent },
  { path: 'plataformas', component: PlatformsListingComponent },
  { path: 'usuarios', component: UsersListingComponent },

  { path: 'jogos/cadastrar', component: GamesRegisterComponent },
  { path: 'fabricantes/cadastrar', component: ManufacturesRegisterComponent },
  { path: 'plataformas/cadastrar', component: PlatformsRegisterComponent },
  { path: 'usuarios/cadastrar', component: UsersRegisterComponent },

  { path: '**', component: GamesListingComponent }

];

export const routing = RouterModule.forRoot(appRoutes);`

header.component.html

        <li class="nav-item" [routerLinkActive]="['active']">
            <a class="nav-link" [routerLink]="['/inicio']">Início <span class="sr-only">(current)</span></a>
        </li>
        <li class="nav-item" [routerLinkActive]="['active']">
            <a class="nav-link" [routerLink]="['/plataformas']">Plataformas</a>
        </li>
        <li class="nav-item" [routerLinkActive]="['active']">
            <a class="nav-link" [routerLink]="['/fabricantes']">Fabricantes</a>
        </li>
        <li class="nav-item" [routerLinkActive]="['active']">
            <a class="nav-link" [routerLink]="['/usuarios']">Usuários</a>
        </li>
        <li class="nav-item" [routerLinkActive]="['active']" >
            <a class="nav-link" [routerLink]="['/jogos']">Jogos</a>
        </li>

XXX-listing.component.html

<a [routerLink]="['/jogos/cadastrar']" class="btn btn-primary">
  Novo Jogo
</a>

Answer 2

如果您要激活两个链接的路线，请按以下方式更改您的html文件，

<nav class='navbar navbar-expand navbar-light bg-light'>
   <div class='width-100'>
     <div class='float-left'> 
    <ul class='nav nav-pills'>   
      <li><a class='nav-link' [routerLinkActive]="['active']" [routerLinkActiveOptions]="{exact:true}"[routerLink]="['/abc']">Abc</a></li>
      <li class="nav-link" [routerLinkActive]="['active']" [routerLinkActiveOptions]="{exact:true}" [routerLink]="['/def']" >Def
               <a routerLink="/ghi"></a>
      </li>
     </ul>
    </div> 
   </div>
</nav>

像这样在app-module.ts文件中定义路由，

imports: [
    BrowserModule,  
    FormsModule,
    RouterModule.forRoot([
      //, canDeactivate : ['canDeactivateCreateEmployee']},
      { path: 'abc', component: AbcComponent },
      { path: 'def', component: DefComponent },
      { path: 'ghi',  component: GhiComponent},
      { path: '', redirectTo: 'AbcComponent', pathMatch: 'full' },
      { path: '**', redirectTo: 'AbcComponent', pathMatch: 'full' }
    ])
  ],

这将使单个RouterLinkActive具有两个URL（def，ghi）
