Angular 2 NgbModal NgbActiveModal 关闭事件模式

Question

我正在使用 Angular 2，我正在使用一个表单模式，我有两个组件，从一个组件我以这种方式打开表单模式:

import { Component, OnInit, Output} from '@angular/core';
import { NgbModal } from '@ng-bootstrap/ng-bootstrap';
import { MyFormComponent } from '......./....';


@Component({
    moduleId: module.id,
    selector: 'my-component',
    templateUrl: 'my-component.html'
})
export class MyComponent implements OnInit {

    private anyData: any;
    private anyDataForm: any;


    constructor(
        private modalService: NgbModal
    ) { }

    ngOnInit(): void {
    }

    open() {
        const modalRef = this.modalService.open(MyFormComponent, { size: 'lg' });
        modalRef.componentInstance.anyDataForm = this.anyData;
    }

    possibleOnCloseEvet() { 
        //Do some actions....
    }

}

open() 方法从 my-component.html 上的按钮触发

在 Form 组件(模态组件)上，我用它来关闭实际模态(从它本身)

import { Component, OnInit, OnDestroy, Input } from '@angular/core';
import { NgbActiveModal } from '@ng-bootstrap/ng-bootstrap';

@Component({
    moduleId: module.id,
    selector: 'my-form-component',
    templateUrl: 'my-form-component.html'
})
export class MyFormComponent implements OnInit, OnDestroy {

    @Input() anyDataForm: any;

    constructor(
        public activeModal: NgbActiveModal
    ) {
    }

    ngOnInit(): void {
    }

    //Some form code...

    OnSubmit() {
        this.activeModal.close(); //It closes successfully
    }

    ngOnDestroy(): void {
    }

}

我需要做的是在调用方组件上触发某种“关闭时”事件，以便仅在模式关闭时在调用方中执行某些操作。 (不能使用事件发射器)

组件打开器有什么方法可以知道模态何时关闭？我还没有找到任何明确的例子。

试试这个:

const modalRef = this.modalService.open(MyFormComponent, { size: 'lg' });
modalRef.componentInstance.anyDataForm = this.anyData;

modalRef.result.then((data) => {
  // on close
}, (reason) => {
  // on dismiss
});
