[英]Not able to bind click event in @Directive in angular4
我有一個簡單的指令,像這樣
import { Directive, HostListener, EventEmitter, Output } from '@angular/core';
@Directive({
selector: '[appAppClick]'
})
export class AppClickDirective {
@Output() clickDirective: EventEmitter<any> = new EventEmitter();
constructor() { }
@HostListener('onClick') onclick() {
debugger;
this.clickDirective.emit();
}
}
現在,我想觸發放置指令的組件的click事件,如下所示
<button type="button" class="btn btn-secondary" data-dismiss="modal" appAppClick (clickDirective)="parentClick()"> Proceed</button>
這是組件ts代碼
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'app';
parentFunc() {
alert('parent function called');
}
}
當我將調試器放置在指令onclick()事件中時,我注意到該事件未得到調用,我對此博客進行了評論
@HostListener('click',['$event']) onclick($event) {
debugger;
this.clickDirective.emit();
}
