Ionic 4 Angular：未捕获的 ReferenceError：dismissModal 未在 HTMLElement.onclick 中定义（但已定义函数！）

Question

错误：未捕获的 ReferenceError：dismissModal 未在 HTMLElement.onclick 中定义

Match-Summary-Modal.component.html

<ion-header translucent>
  <ion-toolbar>
    <ion-title>Match Summary</ion-title>
    <ion-buttons slot="end">
      <ion-button onclick="dismissModal()">Return to Queue Page</ion-button>
    </ion-buttons>
  </ion-toolbar>
</ion-header>
<ion-content>
  <ion-card>
    <ion-card-content>This match you had a score of {{score}}</ion-card-content>
    <ion-card-content>And a place of {{place}} out of {{playerCount}} players</ion-card-content>
  </ion-card>
</ion-content>

Match-Summary-Modal.component.ts

import { Component, OnInit, Input} from '@angular/core';
import { ModalController } from '@ionic/angular';

@Component({
  selector: 'app-match-summary-modal',
  templateUrl: './match-summary-modal.component.html',
  styleUrls: ['./match-summary-modal.component.scss'],
})
export class MatchSummaryModalComponent implements OnInit {
  @Input() score: number;
  @Input() place: number;
  @Input() playerCount: number;


  constructor(private modalController: ModalController) {

   }

  ngOnInit() {}

  async dismissModal() {
    this.modalController.dismiss()
  }

}

GameNetworkService.ts （服务中的某处，注入了 modalController）

this.lobbyServerSocket.on('match-summary', async (summarydata) => {
        let modal = await this.modalController.create({
          component: MatchSummaryModalComponent,
          componentProps: {
            score: summarydata.score,
            place: summarydata.place,
            playerCount: summarydata.playerCount
          }
        })
        await modal.present()
        this.lobbyServerSocket.disconnect(true)
        this.lobbyServerSocket = null;
      })

问题当在dismissModal()中明确定义了dismissModal() ，为什么angular/ionic 无法找到在单击按钮时非常清楚地调用并包含在组件中的dismissModal()方法？

此外，我需要做什么才能获得预期的功能？ （这是使模态在按钮单击时自行关闭）

谢谢！

Answer 1

它应该是

<ion-button (click)="dismissModal()">Return to Queue Page</ion-button>

代替

<ion-button onclick="dismissModal()">Return to Queue Page</ion-button>
