Lightweight and reliable library to check internet connection status.
Compatible browsers: IE 8-11, Opera, Chrome, Firefox, Android, iOS
Include this library into your project and just check is
window.onLine === true.
window.offLineHandler functions to handle status changes.
Just look at example (index.html in the repo)!
You can change
window.onLineURL to point OnlineJS to your own server.

I`m often asked: “Why not just use navigator.onLine ?”. Using this property in critical tasks is bad idea. Property is underhandled and is not consistent among all browsers. It can show local connection status or react only on autonomous mode switching. Online JS is better way for serious project, it uses navigator.onLine and corresponding events as one of possible triggers and then makes more checks of internet connection.
