当用户单击链接时如何隐藏 Angular Material Sidenav

我正在开发一个使用 Material UI 的 Angular 应用程序，我使用 Angular CLI 生成以下代码：

Navigation HTML

<mat-sidenav-container class="sidenav-container">
  <mat-sidenav #drawer class="sidenav" fixedInViewport [attr.role]="(isHandset$ | async) ? 'dialog' : 'navigation'"
    [mode]="(isHandset$ | async) ? 'over' : 'side'" [opened]="(isHandset$ | async) === false">
    <mat-toolbar>
      <mat-icon>keyboard_arrow_down</mat-icon> Select
    </mat-toolbar>
    <mat-nav-list>
      <a mat-list-item [routerLink]="['home']">
        <mat-icon>location_on</mat-icon> - Home
      </a>
    </mat-nav-list>
  </mat-sidenav>
  <mat-sidenav-content>
    <mat-toolbar color="primary">
      <button type="button" aria-label="Toggle sidenav" mat-icon-button (click)="drawer.toggle()"
        *ngIf="isHandset$ | async">
        <mat-icon aria-label="Side nav toggle icon">menu</mat-icon>
      </button>
    </mat-toolbar>
    <!-- Add Content Here -->
    <ng-content></ng-content>
  </mat-sidenav-content>
</mat-sidenav-container>

Navigation TypeScript

import { Component } from '@angular/core';
import { BreakpointObserver, Breakpoints } from '@angular/cdk/layout';
import { Observable } from 'rxjs';
import { map, shareReplay } from 'rxjs/operators';

@Component({
  selector: 'app-navigation',
  templateUrl: './navigation.component.html',
  styleUrls: ['./navigation.component.scss']
})
export class NavigationComponent {

  isHandset$: Observable<boolean> = this.breakpointObserver.observe(Breakpoints.Handset)
    .pipe(
      map(result => result.matches),
      shareReplay()
    );



  constructor(private breakpointObserver: BreakpointObserver) {}

}

我的问题是，我希望当用户单击链接时导航栏关闭（消失）。 我怎么做？当用户单击链接时，导航栏保持启用状态。我必须点击背景的某个地方才能让它消失。

您已经有模板参考#drawersidenav 组件的所以你可以像这样调用切换方法

 <mat-nav-list (click)="drawer.toggle()">
      <a mat-list-item [routerLink]="['home']">
        <mat-icon>location_on</mat-icon> - Home
      </a>
 </mat-nav-list>

如果我们想切换小屏幕（移动设备）的侧边栏底座

成分

  toggle(nav: MatSidenav) {
    const isSmallScreen = this.breakpointObserver.isMatched(
      "(max-width: 599px)"
    );
    if (isSmallScreen) {
      nav.toggle();
    }
  }

模板

 <mat-nav-list (click)="toggle(drawer)">
      <a mat-list-item [routerLink]="['home']">
        <mat-icon>location_on</mat-icon> - Home
      </a>
 </mat-nav-list>
