The launching of external pages can be done directly from your view. Take the following example:

- window.open(‘http://example.com’, ‘_system’);	Loads in the system browser
- window.open(‘http://example.com’, ‘_blank’, 'location=yes');	Loads in the InAppBrowser
- window.open(‘http://example.com’, ‘_blank’, ‘location=no’);	Loads in the InAppBrowser with no location bar
- window.open(‘http://example.com’, ‘_self’);	Loads in the Cordova web view
