Ajax Programming

New to AJAX!


Hi!
   I am new to AJAX,
   I am just trying to develop application using AJAX.
   To start developing AJAX based application I just use the examples
of w3schools.com

    I have one code understanding problem on the page --
    http://www.w3schools.com/ajax/ajax_source.asp

     i,e;
1.
function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("txtHint").innerHTML=xmlHttp.responseText

}
}

 ====================================================================
what this line exactly do:
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")

2. where I could found the good idea about

> getElementById
> responseText
> open
> send
> readyState ...........

Thanks in Advance...........
