AddEventListener不适用于InAppBrowser - IONIC 2

I'm trying to implement AddeventListener to listen 'Exit' and 'LoadStart' for InAppBrowser in IONIC2

我正在尝试实现AddeventListener来监听IONIC2中InAppBrowser的'Exit'和'LoadStart'

my html

<button (click)="browsersystem('https://www.google.com')" > URL</button>

mt.TS file

 browsersystem(url:string)
{
  this.platform.ready().then(() => {
        let browser=open(url, "_system", "location=true"); 
        browser.addEventListener('exit',()=>
        {
          console.log('Browser Closed');
          alert('Browser Closed');

        })

        browser.addEventListener('loadstart',()=>
        {
console.log('Browser STARTED');

        })
        });

}

No errors on console.

控制台没有错误。

Is there something am i missing ??

我错过了什么?

2 个解决方案

#1

import {InAppBrowser} from 'ionic-native';

...

let browser=InAppBrowser.open(url, "_system", "location=true"); 
browser.addEventListener('exit',()=>
{
  console.log('Browser Closed');
  alert('Browser Closed');
});

This is not at all how it's documented / how it should work, but as the code currently stands, this is what works for me.

这根本不是它如何记录/它应该如何工作,但正如代码目前所说,这对我有用。

#2

This should do the trick, see below :

这应该可以解决问题,见下文:

this.platform.ready().then(success => {
      let browser = new InAppBrowser(url, '_system');
      browser.on('exit').subscribe(
            () => {
              console.log('done');
            },
      err => console.error(err));
      });

#1

import {InAppBrowser} from 'ionic-native';

...

let browser=InAppBrowser.open(url, "_system", "location=true"); 
browser.addEventListener('exit',()=>
{
  console.log('Browser Closed');
  alert('Browser Closed');
});
