Simple AJAX based Navigation System


Posted on 25 April 2017

AJAX is catching up the fire in today's world because of its ability to provide versatility and speed to modern world's web application, In this article, we are going to build an AJAX-based navigation system but before that we are going to look at some basic terms which we are going to use in our code.

As we are working with AJAX it means we are directly going to use JavaScript as our main weapon because AJAX is just a method to use the JavaScript's XMLHttpRequest object to interact with the server so we recommend you to learn some basic Javascript before you go through this tutorial.

Some important terms

  • onreadystatechange Used as an event handler for events that trigger upon the state change.
  • readyState Contains the current state of the object.
    0: uninitialised
    1: loading
    2: loaded
    3: interactive
    4: complete
  • responseText Return the response in string format.

We are going to create the following files

  • ajax.js
  • style.css
  • index.html
  • content.html
  • content1.html
  • content2.html

let's start writing the code

	var xmlhttp = new XMLHttpRequest();
	alert("Not supported");
function getRequest(page,pageid,statusid){
	var id = document.getElementById(pageid);
	var status = document.getElementById(statusid);"GET",page);
	xmlhttp.onreadystatechange = function(){
		if(xmlhttp.readyState == 4 && xmlhttp.status == 200){ //if state is 4 and serverstatus is 200 or ok
			id.innerHTML = xmlhttp.responseText;
			status.innerHTML = xmlhttp.statusText;

code for style.css

<!DOCTYPE html>
<title>Ajax Navigation</title>
<link type="text/css" rel="stylesheet" href="style.css" />
<script type="text/javascript" src="ajax.js"></script>
<body onload="getRequest('content.html','home');">
<div class="wrapper">
<a href="#" onclick="getRequest('content.html','home','status');">Home</a> | <a href="#" onclick="getRequest('content1.html','home','status');">Page1</a> | <a href="#" onclick="getRequest('content2.html','home','status')">page2</a>
<div id="home"></div>
<div id="status"></div>

<!---code for content.html -->
<h1>Home Page</h1>
<p>This is a AJAX web page having a simple AJAX based Navigation</p>

<!--- code for content1.html -->
<h1>About page-1</h1>
<p>This is a new page and the page is loaded using AJAX</p>

<!-- code for content2.html -->
<h1>About page-2</h1>
<p>This is a new page and the page is loaded using AJAX</p>
