在“垫”对话框中传递动态对象关键点

Question

if(abc_name === name){
    const dialogRef = this.dialog.open(ViewAbcComponent, {
      panelClass: 'full-screen-dialog-container',
      data: {abc_name: this.abcDetails.item1[keyValue]}
    });
    dialogRef.afterClosed().subscribe((result) => {
      if(result){}
      console.log("ViewAbcComponent dialog closed", result);
    });
  }

Answer 1

您可以在服务中创建subject/BehaviorSubject，并在ViewAbcComponent组件中监听(订阅)该主题。一旦您的数据发生变化，您必须将数据更新为< code > subject . next(data)；您将在组件中获得它。主题示例:

const subject = new Rx.Subject();
subject.next(1);
subject.subscribe(x => console.log(x));

行为主要示例：

const subject = new Rx.BehaviorSubject(0);
subject.next(1);
subject.subscribe(x => console.log(x));

详细说明:(根据要求)

1.您必须在服务中添加可变变量，例如app.service.ts并添加更新html" target="_blank">方法。

const subject = new Rx.Subject();

  updateSubject(data){
   subject.next(data)
  } 

无论您的数据在哪个组件中发生变化，您都必须调用这个updateSubject方法来更新数据。像< code > this . appservice . update subject(updated data)；

在 ViewAbcComponent 组件中，您可以像这样订阅它

this.appService.subject.subscribe（x =
