    Hi All,
    I am completely new to AJAX.
    This is the first program I have come across and I must say I am confused..

    Few of my queries are below:

    I wrote below code in a notepad and saved as html. But I don't know where to place the "ajax_info.txt" file. It dint work when I placed it in the same folder as the .html file
    Also I don't understand and which response are we collecting through xmlhttp.responseText. Because its only on the next line (xmlhttp.open("GET","ajax_info.txt",true) that we actually mention the url/path to which we are trying to connect. So whom are we trying to get response from in : xmlhttp.open("GET","ajax_info.txt",true

    I know its tooooo basic but just cant get a hold of it.



    <!DOCTYPE html>
    <html>
    <head>
    <script>
    function loadXMLDoc()
    {
    var xmlhttp;
    if (window.XMLHttpRequest)
      {// code for IE7+, Firefox, Chrome, Opera, Safari
      xmlhttp=new XMLHttpRequest();
      }
    else
      {// code for IE6, IE5
      xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
      }
    xmlhttp.onreadystatechange=function()
      {
      if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
        document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
        }
      }
    xmlhttp.open("GET","ajax_info.txt",true);
    xmlhttp.send();
    }
    </script>
    </head>
    <body><div id="myDiv"><h2>Let AJAX change this text</h2></div>
    <button type="button" onclick="loadXMLDoc()">Change Content</button></body>
    </html>
