Question

我试图让Side Material Sidenav在打开栏时（显然是在关闭时）推送内容；被推回原位的元素。目前，它的作用是打开内容

See image

这是我的app-header.component.html

<!--- Toolbar starts here-->
<div class="container-toolbar">
    <mat-toolbar color="primary" class="fixed-header">
        <img src="" />
        <button type="button" aria-label="Toggle sidenav" mat-icon-button (click)="drawer.toggle()">
            <mat-icon aria-label="Side nav toggle icon">menu</mat-icon>
        </button>
        <span class="spacer"></span>
        <button type="button" mat-icon-button href="">
            <mat-icon matTooltip="Salir">exit_to_app</mat-icon>

Answer 1

您可以在autosize上使用mat-sidenav-container

模板

<mat-sidenav-container autosize>
  <mat-sidenav #sidenav class="example-sidenav" mode="side" opened="true">

    <mat-nav-list>
      <mat-list-item>
        <button mat-icon-button (click)="isExpanded = !isExpanded">
          <mat-icon *ngIf="!isExpanded">chevron_right</mat-icon>
          <mat-icon *ngIf="isExpanded">chevron_left</mat-icon>
        </button>
      </mat-list-item>
      <mat-list-item>
       <mat-icon mat-list-icon>home</mat-icon>
         <p matLine *ngIf="isExpanded">Home</p>
      </mat-list-item>
    </mat-nav-list>
  </mat-sidenav>

  <div class="example-sidenav-content">
    Main content that resizes properly
  </div>

</mat-sidenav-container>

组件

@Component({
  selector: 'sidenav-autosize-example',
  templateUrl: 'sidenav-autosize-example.html',
  styleUrls: ['sidenav-autosize-example.css'],
})
export class SidenavAutosizeExample {
  isExpanded = false;
}

See it on stackblitz

Answer 2

您不需要[]作为参数。替换：

[mode]="(isHandset$ | async) ? 'side' : 'push'"

作者：

mode="side"

您可能必须在autosize上添加mat-sidenav-container类，就像这样：

<mat-sidenav-container autosize>

Answer 3

固定：只需添加

<router-outlet></router-outlet>

在app-header.component.html文件中的<mat-sidenav-content></mat-sidenav-content>标记内。谢谢大家的回答！

我的sidenav不推送内容，而是克服了它
