cordova – 如何收听inAppBrowser关闭事件

以下是我目前正在使用的代码.我想了解如何监听inAppBrowser关闭事件？当一些人关闭inAppBrowser时,应用程序应显示某种警报消息.

根据documentation我必须使用browser.close(),但这不起作用.

import { Component } from '@angular/core';
import { NavController, NavParams, Platform, LoadingController } from 'ionic-angular';
import { InAppBrowser } from 'ionic-native';

@Component({
  selector: 'page-payment-information',
  templateUrl: 'payment-information.html'
})
export class PaymentInformationPage {

  constructor( public navCtrl: NavController, public navParams: NavParams, public platform: Platform, public loadingCtrl: LoadingController ) {
    this.platform = platform;
  }

  paymentForm(){
      let browser = new InAppBrowser('https://www.stackoverflow.com', '_blank', 'hidden=no,location=no,clearsessioncache=yes,clearcache=yes&enableViewportScale=yes');
      browser.close();
  }

}

你的代码中有一些错误.

从documentation开始,browser.hide()没有做你想做的事情.

Hides an InAppBrowser window that is currently shown. Calling this has
no effect if the InAppBrowser was already hidden.

_blank用_system替换它,因为_blank在inAppBrowser中打开.你将无法听到近距离的事件.

现在,您可以订阅浏览器并收听它的事件,例如

//Events: loadstart, loadstop, loaderror, exit
browser.on('exit').subscribe(() => {
    console.log('browser closed');
}, err => {
    console.error(err);
});
