in the below code i want i have an EventEmitter object as shown in the method onSubmitPost(). when i compile the code the logs in the method onSubmitPost gets displayed. but the logs in the method onReceiveSubmittedEvtEmitter never get displayed. In the follwoing html code
<app-post-create (onPostSubmittedEvtEmitter)="onReceiveSubmittedEvtEmitter($event)"></app-post-create>
method onReceiveSubmittedEvtEmitter should gets executed when the Event onPodtSubmittedEvtEmitter is emitted, but since i do not receive the logs from the method onReceiveSubmittedEvtEmitter, i expect that the event has not been emitted. please let me know why the event has not been emitted and how to fix it
post-create.component.ts:
//logs in this method are displayed onSubmitPost(post: Post) { this.post = { title: this.post.title, content: this.post.content }; this.onPostSubmittedEvtEmitter.emit(this.post); console.log("onSubmit->: post.title: " + post.title); console.log("onSubmit->: post.content:" + post.content); }
post-create.component.html:
<form> <div class="form-group"> <label>Title</label> <input type="text" class="form-control" name="title" required [(ngModel)]="post.title"> </div> <div class="form-group"> <label>Content</label> <textarea name="content" class="form-control" cols="10" rows="2" required [(ngModel)]="post.content"></textarea> </div> <button type="submit" class="btn btn-primary" (click)="onSubmitPost(post)">Create</button> </form>
app.component.ts:
//console logs do not get displayed import { Component } from '@angular/core'; import { Post } from './post-create/post-create.component'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'binding2'; postsArray: Post[] = []; onReceiveSubmittedEvtEmitter(post: Post) { this.postsArray.push(post); console.log("onReceiveSubmittedEvtEmitter->: post.title: " + post.title); console.log("onReceiveSubmittedEvtEmitter->: post.content:" + post.content); } }
app.component.html:
<app-post-create (onPostSubmittedEvtEmitter)="onReceiveSubmittedEvtEmitter($event)"></app-post-create> <app-post-list [postsToAddToList]="postsArray"></app-post-list>
