How to Use AJAX?
AJAX (Asynchronous Javascript and XML) is a client-side technology used to instantiate dynamic, interactive web pages. It provides the ability for you to create real-time Web pages that display information from databases, other parts of the Web, or locally stored data as it becomes available.

//Change the text of a <div> element using an AJAX //request:
//using JQuery
$("button").click(function(){
$.ajax({url: "demo_test.txt", success: function(result){
$("#div1").html(result);
}});
});
//To send a request to a server, we use the open() //and send() methods of the XMLHttpRequest object:
// Javascript
xhttp.open("GET", "ajax_info.txt", true);
xhttp.send();
//example below
<html>
<body>
<h1>The XMLHttpRequest Object</h1>
<button type="button" onclick="loadDoc()">Request data</button>
<p id="demo"></p>
<script>
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
document.getElementById("demo").innerHTML = this.responseText;
}
};
xhttp.open("GET", "demo_get.asp", true);
