我想将模态事件从模态组件传递到模态的父组件,但出于某种原因,我似乎无法使EventEmitter正常工作。如果有人有一个想法,将不胜感激。主要的代码如下,(非工作)普拉克从NG-引导演示分叉是在这里:http://plnkr.co/edit/xZhsqBV2mQaPxqFkoE7C?p=preview事件发射器从引导模态到父节点
app.ts
@Component({
selector: 'my-app',
template: `
<div class="container-fluid" (notifyParent)="getNotification($event)">
<template ngbModalContainer></template>
<ngbd-modal-component ></ngbd-modal-component>
</div>
`
})
export class App {
getNotification(evt) {
console.log('Message received...');
}
}
模式,component.ts
import {Component, Input, Output, EventEmitter} from '@angular/core';
import {NgbModal, NgbActiveModal} from '@ng-bootstrap/ng-bootstrap';
@Component({
selector: 'ngbd-modal-content',
template: `
<div class="modal-body">
<p>Hello, {{name}}!</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" (click)="activeModal.close('Close click')">Close</button>
<button type="button" class="btn btn-secondary" (click)="notify()">Notify</button>
</div>
`
})
export class NgbdModalContent {
@Input() name;
@Output() notifyParent: EventEmitter<any> = new EventEmitter();
constructor(public activeModal: NgbActiveModal) {}
notify(){
console.log('Notify clicked...');
this.notifyParent.emit('Here is an Emit from the Child...');
}
}
@Component({
selector: 'ngbd-modal-component',
templateUrl: 'src/modal-component.html'
})
export class NgbdModalComponent {
constructor(private modalService: NgbModal) {}
open() {
const modalRef = this.modalService.open(NgbdModalContent);
modalRef.componentInstance.name = 'World';
}
}
