Angular material 可拖动对话框不工作

Angular material Dragable dialogbox is not working

我有一个可拖动的对话框,它不起作用。 但是我在另一个项目上有类似的工作代码。

我的主要代码:

<div cdkDrag cdkDragRootElement=".cdk-overlay-pane" >
    <h2 mat-dialog-title cdkDragHandle> Justin Wu</h2>
</div>
<label>I am a {{ position}}</label>
<div>
    <button class="close" mat-button (click)="closeDialog()">Close</button> 
    <button class="save" mat-button  (click)="closeDialog()">Save</button>
</div>

您可以从这里找到演示:http://www.justa999.com/angular/#/profile

点击“关于我”按钮后你会看到它

您可以从 profile.component.ts

调试源代码

我的版本:

尝试

<h2 mat-dialog-title cdkDrag cdkDragRootElement=".cdk-overlay-pane" cdkDragHandle> Justin Wu</h2>
<div mat-dialog-content >
<label>I am a {{ position}}</label>
</div>
<div mat-dialog-actions>
   <button class="close" mat-button (click)="closeDialog()">Close</button> 
   <button class="save" mat-button  (click)="closeDialog()">Save</button>
</div>

Angular Modal 和 CDK Drag 经常重叠,你可以使用普通 div 并设置它的 css

position: absolute;
left: 50px;
top: 50px;

因此它显示为模式,cdkdrag 有效。

我自己解决了这个问题:

首先,您必须将您的内容添加到

<mat-dialog-content>
    <label>I am a {{ position}} </label>
</mat-dialog-content>

其次,您必须在 app.module.ts

中声明您的对话框组件
@NgModule({
  declarations: [
    ModalContentComponent,
