我有以下儿童路线：
{ path: '',component: LoginSingupComponent,children: [
{ path: 'login',component: LoginComponent },{ path: 'singup',component: SingupComponent },]
},
导航到/ login或/ singup工作正常(加载了正确的组件).
这是LoginSingupComponent的摘录
<nav md-tab-nav-bar class="mb-1">
<a md-tab-link routerLink="/login" routerLinkActive [routerLinkActiveOptions]="{exact: true}" #rla="routerLinkActive" [active]="rla.isActive">Entrar {{rla.isActive}}</a>
<a md-tab-link routerLink="/singup" routerLinkActive [routerLinkActiveOptions]="{exact: true}" #rla="routerLinkActive" [active]="rla.isActive">Criar uma conta{{rla.isActive}}</a>
</nav>
当打开/登录时,所有rla.isActive == false,当打开/ singup时,所有rla.isActive == true
尝试使用和不使用exact：true
解决方法
试试这样：
<nav md-tab-nav-bar class="mb-1">
<a md-tab-link [routerLink]="['/']" routerLinkActive="active" [routerLinkActiveOptions]="{exact: true}">Home</a>
<a md-tab-link [routerLink]="['/login']" routerLinkActive="active">Login</a>
<a md-tab-link [routerLink]="['/singup']" routerLinkActive="active">Signup</a>
</nav>
