HTML has XMLHttpRequest for determining network availability.
HTML5, though, made it even easier and introduced a way to check whether
the browser can accept web responses. This is achieved via the navigator object:
if (navigator.onLine) {
alert("You are Online");
}
else {
alert("You are Offline");
}

the following are two polyfills for checking network connectivity:

The first one is using XMLHttpRequest, similar to what Smartphone APIs do.

odernizr, a well-known library for detecting HTML5 and CSS3 features, provides
a great list of HTML5 polyfills that can make your life much easier when it comes
to supporting older browsers. Regardless of which HTML5 feature you are using,
there is a corresponding polyfill available at https://github.com/Modernizr/
