我想根据路线切换routerLinkActive的高亮显示, 我有一个仪表板组件,并且仪表板菜单项和标签菜单项都引用相同的组件,我想根据路线将类添加到li项中 对于仪表板,路线将为
http://localhost:4300/dashboard
对于标签,路线将为
http://localhost:4300/dashboard/5d1bb53877ed8702d8a01940
菜单项的代码
<ul class="sidebar-nav">
<li [ngClass]="{ active: rlal && rlal.isActive == false }">
<a [routerLink]="['/dashboard']" (click)="loadSnippet(null)">
<mat-icon>dashboard</mat-icon>
<span>Dashboard</span>
</a>
</li>
<h3 *ngIf="labelList && labelList.length!=0">Labels</h3>
<ul class="sidebar-nav">
<li *ngFor="let label of labelList" [ngClass]="rlal && rlal.isActive ? 'active' : ''"
routerLinkActive="rlal.isActive">
<a [routerLink]="['/dashboard', label._id]" routerLinkActive #rlal="routerLinkActive"
(click)="loadSnippet(label)">
<mat-icon>label</mat-icon>
<span>{{ label.label_name }} </span>
</a>
</li>
</ul>
路线:
{
path: "dashboard",
component: DashboardComponent,
canActivate: [LoggedInGuard]
},
{
path: "dashboard/:labelId",
component: DashboardComponent,
canActivate: [LoggedInGuard]
}
突出显示对单个标签项目效果很好,但是对于仪表板,li不会突出显示
答案 0 :(得分:1)
如果仅在没有路由参数的情况下才希望仪表板链接处于活动状态,则需要向仪表板routerLinkActive
节点添加[routerLinkActiveOptions]="{exact: true}"
和li
。
此外,您无需通过active
来设置ngClass
类,因为routerLinkActive
会为您完成此操作。
<li routerLinkActive="active" [routerLinkActiveOptions]="{exact: true}">
<a routerLink="/dashboard" (click)="loadSnippet(null)">
<mat-icon>dashboard</mat-icon>
<span>Dashboard</span>
</a>
</li>
...
<li routerLinkActive="active" *ngFor="let label of labelList">
<a [routerLink]="['/dashboard', label._id]" (click)="loadSnippet(label)">
<mat-icon>label</mat-icon>
<span>{{ label.label_name }}</span>
</a>
</li>
