Question

我在Angular应用中添加了Hamburger Nav。问题是，当我从路由器导航通过导航时，导航div卡住了并且不会自动关闭。我已经使用CSS创建了这个，而没有使用jquery。我应该在我的导航控制器文件中添加一些js代码来做些什么来纠正它。附上截图以更好地理解问题。

SCREEN 1 Component：首页

SCREEN 2组件：收据（Nav Div卡住了。没有关闭）

NAV.COMPONENT.HTML

<header tabindex="0">
  <h4>{{ pagename }}</h4>
  <a (click)="winBack()">Back</a>
</header>
<div id="nav-container">
  <div class="bg"></div>
  <div class="button" tabindex="0">
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
  </div>
  <div id="nav-content" tabindex="0">
    <ul>
      <li *ngFor="let nav of navs; let i = index">
        <a (click)="route(i)"><i :class="{{nav.fa}}"></i>&nbsp; {{nav.name}}</a>
      </li>
      <li><a routerLink="/app1/three"><i class="fa fa-camera"></i>&nbsp; Scanner</a></li>
      <li style="margin-top:15px;"><a><i class="fa fa-user"></i>&nbsp; {{ logname }}</a>
      <li (click)="logOut()"><a><i class="fa fa-sign-out"></i>&nbsp; Logout</a></li>
    </ul>
  </div>
</div>
<router-outlet></router-outlet>

NAV.COMPONENT.TS（仅路由部分）

  route(i){
    console.log(i)
    if (i == 0) this.router.navigate(["/app1/home"])
    else if (i == 1) this.router.navigate(["/app1/receipt"])
    else if (i == 2) this.router.navigate(["/app1/issue"])
    else if (i == 3) this.router.navigate(["/app1/transfer"])
    else if (i == 4) this.router.navigate(["/app1/summary"])
  }

Answer 1

您可以使用ngIf来隐藏您的导航div

<div id="nav-container" *ngIf="isNavOpened">

然后在您的组件中

isNavOpened=true;

route(i){
this.isNavOpened=false;
}

或者，如果您不想使用ngif

，也可以使用一些条件类

导航到角路由器后导航未关闭
