Using JavaScript code to Check if the Internet Connection is Available

To avoid situations where something you create misbehaves because an internet connection isn't available, you need a way to detect whether an internet connection exists. In this post, we will Using JavaScript code to Check if the Internet Connection is Available

Introduction

If there is ever a moment when you need your internet connection to work, there is a very good chance it is at that very moment your internet connection will fail.

In this post and code example, we will use JavaScript code to check if the Internet connection is available or not on a machine. The JavaScript can be placed in a Web page.

JavaScript Navigator.OnLine property it used to check if the Internet connection is available on a machine or not. It returns a true value if the internet is available. It returns false of the internet is not available.

The following code example is an HTML web page that uses navigator.OnLine property on a button clicks to check the internet connection.

Example:

<html>  
<head>  
<title>internet check</title>  
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">  
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>  
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>  
</head>  
<body>  
<div class="container">  
<div class="row">  
<span>Click on the button to check the internet available or not</span> <button type="button" class="btn btn-success" onclick="internetCheck()">Try</button>  
</div>  
<span id="internetCheck"></span>  
</div>  
<script>  
function internetCheck() {  
  var value = "Is the browser online? " + navigator.onLine;  
  document.getElementById("internetCheck").innerHTML = value ;  
}  
</script>  
  
</body>  
</html>  

Summary

More and more of your sites and apps store state in a remote location. Having an internet connection at all times when using your phone or computer or whatever is no longer a luxury for many parts of the world. It is a necessity.

For those moments when your site or app doesn't have an internet connection that it desperately relies on, this code provides you with a basic solution for how to start dealing with it.

Functional Programming for JavaScript Developers

Functional Programming for JavaScript Developers

Functional Programming for JavaScript Developers. Learn Functional Programming and how it enables developers to move from imperative to declarative programming. Solidify your knowledge of functional JavaScript programming, including objects, arrays, and prototypes. Learn higher-order functions, closures, scope, master key functional methods like map, reduce and filter and promises and ES6+ asynchronous JavaScript. Learning how to build and manage asynchronous functional programs is perhaps the most important part of becoming an effective JavaScript programmer.

Functional Programming for JavaScript Developers

Learn functional programming and how it enables developers to move from imperative to declarative programming

Improve your code with functional patterns like pure functions, compose & map/reduce/filter...plus advanced concepts like fusion, transducing and monads!

Solidify your knowledge of functional JavaScript programming, including objects, arrays, and prototypes

Learn higher-order functions, closures, scope, master key functional methods like map, reduce and filter and promises and ES6+ asynchronous JavaScript. Go beyond the fundamentals of asynchronous JavaScript and use features and techniques that will help you reduce code and create smarter applications.

Learning how to build and manage asynchronous functional programs is perhaps the most important part of becoming an effective JavaScript programmer.

What you'll learn

  • On the surface, this course is designed for beginning and intermediate JS developers who want to learn the fundamentals in order to understand and use functional programming in both ES5 and ES6. However, this course is also perfect for people preparing to enter into competitive JavaScript bootcamps
