导航后角度材质对话框未关闭 [英] Angular Material Dialog not closing after navigation

问题描述

我正在开发一个显示数据表中实体概览的应用程序.每个实体都有链接的实体，在列中显示为xxx 个链接的实体".当用户单击该列的值时，将打开一个显示链接实体列表的材料对话框.这些都是与其他实体的链接.单击这些链接之一后，将显示实体的正确页面，但该对话框不会关闭.使用后退按钮时我确实关闭了.我正在使用 closeOnNavigation 属性.

I'm working on an application that shows an overview of entities in a datatable. Every entity has linked entities that are shown as 'xxx linked entities' in a column. When the user clicks on the value of that column, a material dialog opens showing the list of the linked entities. These are all links to other entities. Upon clicking one of these links, the correct page of the entity is shown, but the dialog doesn't close. I does close when using the back button. I am using the closeOnNavigation property.

一些示例代码:

在我的主要组件中:

public openDialog(entity: Entity) {
    const dialogRef = this.dialog.open(EntityDialogComponent, {
        closeOnNavigation: true,
        data: {
            entity,
            otherEntities: this.getNameOfOtherEntities(),
        },
    });
}

对话框的Html:

<h1 mat-dialog-title>Linked {{otherEntities}}:</h1>
<mat-dialog-content>
<mat-list role="list">
    <mat-list-item role="listitem" *ngFor="let linkedEntity of entity.getProperty('linkedEntities')">
       <a class="m-link m--font-bold" [routerLink]="['/reporting/' + otherEntities, linkedEntity.id]">{{linkedEntity.name}}</a>
    </mat-list-item>
</mat-list>
</mat-dialog-content>
<mat-dialog-actions>
    <button mat-button (click)="cancel()">Close</button>
</mat-dialog-actions>

对话框组件:

@Component({
    selector: "entity-dialog",
    templateUrl: "entity-dialog.component.html",
})
export class EntityDialogComponent {

    public entity: Entity;
    public otherEntities: string;

    constructor(
        public dialogRef: MatDialogRef<EntityDialogComponent>,
        @Inject(MAT_DIALOG_DATA) public data: IDialogData,
    ) {
        this.entity = data.entity;
        this.otherEntities = data.otherEntities;
    }

    public cancel(): void {
        this.dialogRef.close();
    }

}

附注:

当我在特定实体页面上时，我单击数据表以打开模态并单击指向另一个实体的链接，页面滚动到顶部，浏览器中的链接更改为正确的链接，但是由于某种原因，页面没有刷新.有什么想法吗?

When I'm on a specific entity page, and I click in a datatable to open a modal and click a link to another entity, the page scrolls to the top, the link in the browser changes to the correct link, but the page doesn't get refreshed for some reason. Any ideas?

推荐答案

根据它所说的文档:closeOnNavigation:当用户在历史中向后/向前移动时，对话框是否应该关闭.

Hi according to the docs it says: closeOnNavigation: Whether the dialog should close when the user goes backwards/forwards in history.

历史导航通常表示浏览器的后退和前进按钮:https://developer.mozilla.org/en-US/docs/Web/API/History_API

History Navigation Normally means browser back and forward buttons: https://developer.mozilla.org/en-US/docs/Web/API/History_API

在您的场景中，您可以做的不是直接从 html 路由，而是创建一个函数，该函数将在对话框关闭后进行路由，这样您可以确保在启动导航之前先关闭对话框.

What you could do in your scenario however is instead of routing directly from your html is create a function that will route after the dialog is closed this way you can ensure that you close the dialog first before initiating your navigation.

   <a class="m-link m--font-bold" (mousedown)="navigateToEntity($event)">{{linkedEntity.name}}</a>

在你的组件里面有类似的东西

Inside your component have something like

  navigateToEntity(event) {
    this.dialogRef.afterClosed.pipe(
      tap(() => this.router.navigate(['navigate to wherever'])),
      first()
    ).subscribe();
    this.dialogRef.close();
  }

希望这会有所帮助，我对 Material Components 的工作不多，但阅读了一些文档，这是我实现它的方式.

Hope this helps, i haven't worked much with Material Components but reading through some of the docs this is how i would implement it.
