Question

页面加载时，mat-sidenav处于打开状态。如何关闭它？

这是我的HTML：

<mat-sidenav
    #drawer
    class="sidenav" position="end"
    fixedInViewport="true"
    [attr.role]="(isHandset$ | async) ? 'dialog' : 'navigation'"
    [mode]="(isHandset$ | async) ? 'over' : 'side'"
    [opened]="!(isHandset$ | async)">
    <mat-toolbar color="warn">Menu</mat-toolbar>
    <mat-nav-list>
      <a mat-list-item [routerLink] = "['/brands']"> Brands </a>
      <a mat-list-item [routerLink] = "['/variants']"> Variants </a>
    </mat-nav-list>
</mat-sidenav>

此外，当我在页面中的任意位置单击时，我希望它接近(打开时)。目前，只有当我单击菜单按钮时，它才会关闭。

试试下面这段，

<mat-sidenav-container class="sidenav-container">
  <mat-sidenav
    #drawer
    class="sidenav"
    fixedInViewport="true"
    [attr.role]="(isHandset$ | async) ? 'dialog' : 'navigation'"
    [mode]="(isHandset$ | async) ? 'over' : 'side'"
    [opened]="!(isHandset$ | async)">
    <mat-toolbar color="warn">Menu</mat-toolbar>
    <mat-nav-list>
      <a mat-list-item [routerLink] = "['/brands']"> Brands </a>
      <a mat-list-item [routerLink] = "['/variants']"> Variants </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>
      <span>Application Title</span>
    </mat-toolbar>
  </mat-sidenav-content>
</mat-sidenav-container>

你可以试试，它对我的工作很有效

<mat-nav-list>
  <a mat-list-item [routerLink] = "['/brands']" (click)="drawer.close()"> Brands </a>
  <a mat-list-item [routerLink] = "['/variants']" (click)="drawer.close()"> Variants </a>
</mat-nav-list>
