Angular 材质的对话框无法与 hasBackdrop 属性或我指定的任何其他属性一起正常工作

问题描述 投票:0回答:0

我正在尝试将对话框与我的应用程序合并,但我分配的任何属性,例如 hasBackdrop = true (我知道这是默认值),都不会改变行为。当对话框打开时,我可以单击 UI 中的任意位置并与其交互,同时对话框保持打开状态。因此,我能够进行 API 调用,甚至打开多个对话框。

这是我的 ts 文件和 html 文件的一些片段。

export class MenuItemsComponent{

    constructor(private dialog: MatDialog){}

    @Input() menuItemsPerCategory: MenuItemModel[] = [];

    openDialog():void{
        const dialogConfig = new MatDialogConfig();
        dialogConfig.hasBackdrop = true;
        
        const dialogRef = this.dialog.open(MenuItemDialogContainer, dialogConfig);
    }

<div (click)="openDialog()">
    {{ menuItemsPerCategory[0].name }}
</div>
}

此外,在应用程序模块文件中,我尝试在提供者数组下分配此对象,没有任何明显的更改。

   { provide: MAT_DIALOG_DEFAULT_OPTIONS, useValue: {hasBackdrop: false} }

这是我的 package.json 文件

}

我什至访问了 Material 的官方文档页面(https://material.angular.io/components/dialog/examples),单击了 StackBlitz 的一个示例,并在 Visual Studio 代码中进行了直接复制和粘贴工作。不幸的是,我的功能并没有模仿我在 StackBlitz 上看到的功能。我在复制和粘贴作业中看到的是,当我单击它时,对话框保持打开状态,并且我能够打开多个对话框。

import { Component } from '@angular/core';
import { MatDialog } from '@angular/material/dialog';

@Component({
  selector: 'app-root',
  template: `<button mat-button (click)="openDialog()">Launch dialog</button>`,
  //styleUrls: ['./app.component.css']
})
export class AppComponent {
  constructor(public dialog: MatDialog) {}

  openDialog() {
    this.dialog.open(DialogElementsExampleDialog);
  }
}

@Component({
  selector: 'dialog-elements-example-dialog',
  template: `<h1 mat-dialog-title>Dialog with elements</h1>
             <div mat-dialog-content>This dialog showcases the title, close, content and actions elements.</div>
             <div mat-dialog-actions>
             <button mat-button mat-dialog-close>Close</button>
             </div>
            `
})
export class DialogElementsExampleDialog {}
