Current behavior:
InAppBrowser cordova plugin emit event, callback function has only one argument< InAppBrowserEvent>.
(params: InAppBrowserEvent) => void

But, 'beforeload' event callback function has 2 arguments,
(params: InAppBrowserEvent, callback: (url:string) => void) => void

Now, ionic-native in-app-browser plugin provide only one argument, when 'beforeload' too.
Open url depends on called callback function.

Expected behavior:
When 'beforeload' event provide all arguments, InAppBrowserEvent and Callback Function.

Related code:

const browser = this.inAppBrowser.create(url, '_blank', this.options);
browser.on('beforeload').subscribe((...args) => {
        console.log(args); // args is only InAppBrowserEvent
      });

Case of Cordova Plugin.

inAppBrowserRef.addEventListener('beforeload', beforeloadCallBack);

function beforeloadCallBack(params, callback) {
    if (params.url.startsWith("http://www.example.com/")) {
        // Load this URL in the inAppBrowser.
        callback(params.url);
    } else {
        // The callback is not invoked, so the page will not be loaded.
        $('#status-message').text("This browser only opens pages on http://www.example.com/");
    }
}

How can I provide two argument in ionic-native plugin?
If it possible, I fixed and pull request this issue.
thx.

This is an issue I am having as well.

Was this solved by any chance?

Is there any way to use this event in Ionic 4 with new on('beforeload').subscribe interface? Right now I see no way of calling callback, so InAppBrowser hangs on processing this event.

Currently facing this issue as well. How do we pass the param.url back to the InAppBrowser so it will navigate as expected?

Submited a PR to add the "_loadAfterBeforeload" method to the InAppBrowser instance, I was able to get this working with "@ionic-native/in-app-browser": "^4.20.0" since we're still on Ionic v3.

const iabRef = this.iab.create(url, target, options);
iabRef.on("beforeload").subscribe((evt: InAppBrowserEvent) => {
    // This will execute the URL you clicked on
    iabRef._loadAfterBeforeload(evt.url);
});
