Question

我使用Angular 2，我正在使用表单模式，我有两个组件，从一个组件我打开表单模式这样：

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）上我使用它来关闭实际模态（从它自己）

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 {
    }

}

我需要做的是在关闭时解雇某些＆＃34;调用方组件上的事件仅在模式关闭时才在调用方中执行某些操作。（不能使用事件发射器）

组件开启器有什么方法可以知道模态何时关闭？我没有找到任何明确的例子。

Answer 1

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
});

Answer 2

在我的ModalformComponent上

 this.activeModal.close('success');

然后在我的父组件ListComponent上

 this.modalRef = this.modalService.open(ModalformComponent);
 this.modalRef.componentInstance.title = 'Add Record';
 this.modalRef.result.then((result) => {
  if ( result === 'success' ) {
     this.refreshData(); // Refresh Data in table grid
  }
}, (reason) => {
});

Answer 3

你可以在MyFormComponent中添加

closeModal（）{this.activeModal.close（anything）; }

Answer 4

使用this.activeModal.close();代替this.activeModal.dismissAll()。它将成功关闭弹出窗口。

角度2 NgbModal NgbActiveModal关闭事件模态
