Ionic 4 Angular：未捕獲的 ReferenceError：dismissModal 未在 HTMLElement.onclick 中定義（但已定義函數！）

Question

錯誤：未捕獲的 ReferenceError：dismissModal 未在 HTMLElement.onclick 中定義

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 （服務中的某處，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;
      })

問題當在dismissModal()中明確定義了dismissModal() ，為什么angular/ionic 無法找到在單擊按鈕時非常清楚地調用並包含在組件中的dismissModal()方法？

此外，我需要做什么才能獲得預期的功能？ （這是使模態在按鈕單擊時自行關閉）

謝謝！

Answer 1

它應該是

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

代替

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