I've had a few requests for something like this.

Source Code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Sample Ajax</title>
<script type="text/javascript">
function updateArea()
{
var ajaxRequest;
if (window.XMLHttpRequest)
{
ajaxRequest = new XMLHttpRequest();
}
else
{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP" );
}
ajaxRequest.onreadystatechange = function()
{
if (ajaxRequest.readyState == 4 && ajaxRequest.status == 200)
{
document.getElementById("area" ).innerHTML = ajaxRequest.responseText;
}
}
ajaxRequest.open("GET","getPage.php",true);
ajaxRequest.send();
}
</script>
</head>
<body onload="setInterval('update()', 5000)">
<div id="area">
<p>Before</p>
</div>
</body>
</html>

Source Code
<p>After</p>

Issue#1: Too complicated. Dumb it down.

Language is a tool for efficient communication. The internet is a tool for fast communication. Do not defy both intents by posting incoherent writing.

@carlos11 You obviously don't program web sites.

@carlos11
This is AJAX.
Unless you're using a library, it doesn't get any simpler than this.

AJAX is not a library. The XMLHttpRequest object is just that--an object that contains property values and methods.

A library is an abstraction of code that combines one or more core features of a language to make future code easier, simpler, and maybe even more efficient.

@CoolApps
no, it isnt
do you need to do some stuff like <script src='ajax.js'></script> to use it?
no
no you dont

SPCOxion (2014-06-29 08:16:21)

Yes, it does.

If it's something you can include in files to make tedious tasks faster, it's a library.

Hell, you could even technically make yourself a 'mini-library' for your own needs.

SPCOxion (2014-06-30 16:07:27)

Yeah.

Most people probably do that in the first place, just to make things easier for themselves.

By the way, if you really want to use a $displayIP on your website, you should look into proxy detection, accurate IP guesses, etc.

If you think everything above is too hard, try mircoAjax, a tiny Ajax Library created by Stefan Lange-Hegermann.

<script src="http://microajax.googlecode.com/svn/trunk/microajax.js"></script>

<script>
microAjax("/resource/url", function (res) {
alert (res);
});
</script>

If this doesn't help you, you are on your own!

GuitarBoy is correct when he mentioned about Ajax not being a library.
