Test if browser have internet connection using HTML5

Is there any new HTML5 API, I couldn't find anything, that will check if user have internet connection. Or maybe there is unusual use of some API that will allow to do this. I had to test it and I've used ajax call to test, is there other method?

In some new browsers there is the navigator.onLine property and the online and offline events. See https://developer.mozilla.org/en-US/docs/Web/API/NavigatorOnLine.onLine

Failing that, you could try an Image element instead of AJAX (assuming you can find a consistent image URL that won't disappear). This has the advantage of not needing to worry about cross-origin security limitations that make it hard to distinguish a failed AJAX call from one that was blocked because of CORS issues.
