p-dialog onHide无法在角度2分量中工作-Primeng [英] p-dialog onHide not working in angular 2 component - primeng

问题描述

我在angular 2应用程序中使用primeng并面临此问题

I'm using primeng in an angular 2 application and facing this issue (stackoverflow question)

尽管接受的答案中提供的plunkr起作用，但在我的情况下却不起作用.我有一个单独的组件，该组件根据父组件的输入来加载.我想在子组件关闭/隐藏时切换可见性标志.

Although the plunkr provided in the accepted answer works but it doesn't in my scenario. I have a separate component that loads the based on an input from the parent component. I want to toggle the visibility flag when the child component is closed/hidden.

这是代码段

 <p-dialog header="Assets Management" [(visible)]="showDialog" modal="modal" [closable]="true" (onHide)="close()" appendTo="body">
          .. some content ..
  </p-dialog>

在组件中，我有:

@Component({
    selector: 'view-car-colors',
    templateUrl: '/view-car-colors.html',
    inputs: ['showDialog'],
    outputs: ["onCloseDialog"],
})
export class ViewCarColorsComponent {
    private showDialog: boolean = false;    //default close
    private onCloseDialog: EventEmitter<any> = new EventEmitter();

    public close(): void {
        this.showDialog = false;
        //emit this to its parent
        this.onCloseDialog.emit({ hasChanges: true });
    }
}

最后在我的父组件中，我这样称呼它:

And finally in my parent component, I am calling it like:

<view-car-colors [showDialog]="showCarColorsDialog" (onCloseDialog)="onCarColorsCloseDialog($event)"></view-car-colors>

通过单击按钮更改showCarColorsDialog的位置.

Where showCarColorsDialog is changed based on a button click.

private onCarColorsCloseDialog($event: any): void {
    this.showCarColorsDialog = false;
    if ($event.hasChanges) {
        //fetch the changes again
        this.getCarColors();
    }
}

我在多个地方都使用了primeng控件，它们都可以正常工作，但是有这个问题，所以我敢肯定不是因为版本.

I have used the primeng controls on multiple places and they all work fine but just has this issue so I'm sure it can't be because of the version.

推荐答案

尝试(onAfterHide)="close()".
