InAppBrowser event.url always undefined

Question

Do you have any idea why event.url always undefined? This is for loadstart and loadstop.

The google page was displayed fine on pop up window.

var ref = window.open('http://google.com', '_blank', 'location=yes');
ref.addEventListener('loadstart', function() { alert('start: ' + event.url); });
ref.addEventListener('loadstop', function() { alert('stop: ' + event.url); });
ref.addEventListener('exit', function() { alert(event.type); });

Answer 1

var ref = window.open('http://google.com', '_blank', 'location=yes');
ref.addEventListener('loadstart', function(event) { alert('start: ' + event.url); });
ref.addEventListener('loadstop', function(event) { alert('stop: ' + event.url); });
ref.addEventListener('exit', function(event) { alert(event.type); });

The callback function is called when the event is fired. The function is passed an InAppBrowserEvent object.
