Check if user is connected to internet or not in JavaScript

Sometimes it happens that a user is using your website and suddenly internet got disconnected. But how do you notify the end user about this.

Navigator.onLine

JavaScript has come up with a property ‘onLine’. ’onLine’ returns true if the user is connected to internet and false if disconnected.

Example

<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

<head>
	<meta charset="utf-8" />
	<title></title>
	<script>
	alert(navigator.onLine);
	</script>
</head>

<body> </body>

</html>

Above code prompts true if user is connected to internet and false if disconnected.
