Question

Is it possible to detect if the user is accessing through the browser or application using JavaScript?

I’m developing a hybrid application to several mobile OS through a web page and a PhoneGap application and the goal would be to:

1. Use the same code independently of the deployment target
2. Add PhoneGap.js file only when the user agent is an application

Answer 1

You could check if the current URL contains http protocol.

var app = document.URL.indexOf( 'http://' ) === -1 && document.URL.indexOf( 'https://' ) === -1;
if ( app ) {
    // PhoneGap application
} else {
    // Web page
}
