angular - 如何在 MatDialog 中使用 scrollStrategy？

Question

我试图为重新定位策略中的对话框制作滚动条，但它对我不起作用。

const scrollStrategy = this.overlay.scrollStrategies.reposition();
const dialogRef = this.dialog.open( DialogOverviewExampleDialog, { scrollStrategy } );

The full example

我希望在滚动过程中整个对话框(元素.cdk-overlay-pane)会移动

如果你想滚动对话框的内容，那么你必须使用 <mat-dialog-content>标记，或在您的 div 元素中使用指令 mat-dialog-content。在您的示例中，改为尝试以下操作:

<h1 mat-dialog-title>Hi {{data.name}}</h1>
<mat-dialog-content> <!-- instead of your <div>  or use <div mat-dialog-content> -->
  <p>What's your favorite animal!!!!!!!</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal?</p>
  <p>What's your favorite animal!!!!!!</p>
  <mat-form-field>
    <input matInput [(ngModel)]="data.animal">
  </mat-form-field>
</mat-dialog-content> <!-- instead of your </div> -->
<div mat-dialog-actions>
  <button mat-button (click)="onNoClick()">No Thanks</button>
  <button mat-button [mat-dialog-close]="data.animal" cdkFocusInitial>Ok</button>
</div>

现在您的对话框内容应该在侧面有一个滚动条。在以下位置阅读有关对话框的可滚动内容容器的更多信息:
