小编Apo*_*llo的帖子

我正在开发一个角色应用程序供管理人员跟踪他们的团队,我遇到了@Output错误:

An error occurred: @Output deleteMeeting not initialized in 'MeetingItemComponent'.

我有一个Meetings组件,生成一个MeetingItem组件列表.我想在用户点击不同按钮(编辑,删除,显示详细信息)时执行操作.

    <mat-icon (click)="onOpenMeetingDialog(meeting)" matTooltip="Edit this meeting" matTooltipPosition="above" class="icon--edit">edit</mat-icon>
    <mat-icon (click)="onDeleteMeeting(meeting.id)" matTooltip="Delete this meeting" matTooltipPosition="above" class="icon--delete">delete_outline</mat-icon>
  </span>

我的MeetingItem组件:

import { Component, Input, Output } from '@angular/core';
import { EventEmitter } from 'events';

@Component({
  selector: 'app-meeting-item',
  templateUrl: './meeting-item.component.html',
  styleUrls: ['./meeting-item.component.scss']
})
export class MeetingItemComponent {

  @Input() …
