Check If User Is Connected To Internet Or Not In Javascript

Sometimes, a user is using your website when the internet suddenly disconnects. How do you notify the end user about this?

Navigator.Online

JavaScript has introduced a property called onLine. The onLine property returns true if the user is connected to the internet and false if disconnected.

Example

<script>
	document.write(navigator.onLine);
</script>

Try It

The code above checks internet connectivity, returning true when online and false when offline.
