Download Javascript file

I have used the Simple Ajax Code Kit library(SACK) for this script. I have made a copy available for download here.

Put ajax.js in a subfolder called "js" or change the path to the file in the code above(i.e. <script type="text/javascript" src="js/ajax.js"></script>)


This script is a simple demo that hopefully shows you some of the benefits of AJAX.

The list you see on the right side of the demo is a group of articles. The HTML code for this list looks like this:

  <ul id="articleList" class="articleList">
    <li id="article1">This is article number one</li>
    <li id="article2">This is the second article</li>
    <li id="article3">Article number 3</li>
    <li id="article4">About AJAX</li>
    <li id="article5">Article number 5</li>
    <li id="article6">Article number 6</li>
    <li id="article7">Article number 7</li>
    <li id="article8">Article number 8</li>
    <li id="article9">Article number 9</li>

Each <LI> represents an article. I have given each <LI> it's unique ID( Example: <li id="article1">, <li id="article2"). In this example, the id represents the name of external files.

When someone clicks on one of the articles in the list, my script will use AJAX to return the content of a file equal to the ID of the clicked article + ".html". Example: When you click on <LI id="article1">, the script will show you the content of the file "article1.html".

Short about AJAX functions

An "AJAX" Javascript object is created at the top of my script with this line:
var ajax = new sack();

Now, when someone clicks on an article in the list, we configure this object to request the external file. Example:
function getAjaxFile(fileName)
  ajax.requestFile = fileName;
  ajax.onCompletion = showContent;
  ajax.onLoading = showWaitMessage;

  • ajax.requestFile specifies which file to return
  • ajax.onCompletion = showContent; specifies the name of the function that should be executeed when AJAX finish it's job getting the external file
  • ajax.onLoading = showWaitMessage; specifies a function that should be executed while AJAX is working
  • ajax.runAJAX(); executes AJAX

Create external files

I have used 9 dummy articles for this demo. I have just named them article1.html, article2.html ... article9.html. You can download them from this Zip file or create your own articles.


This is awesome, Thanks for sharing your cool ideas.

The files should be in the same folder as the main html file.If you're still not able to make it work, please take a look a this article: http://www.dhtmlgoodies.com/forum/viewtopic.php?f=30&t=568

function showUser(str)
if (str=="")
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
if (xmlhttp.readyState != 0 && xmlhttp.status==200)

Select a person:
Peter Griffin
Lois Griffin
Glenn Quagmire
Joseph Swanson

On my next file getuser:


$con = mysql_connect('localhost', 'root', '');
if (!$con)
die('Could not connect: ' . mysql_error());

mysql_select_db("stock1", $con);

$sql="SELECT * FROM item WHERE item = '".$q."'";

$result = mysql_query($sql);

while($row = mysql_fetch_array($result)){
echo ' ItemCode : ';
echo ' Unit Price : ';
echo ' ItemCounter : ';

Nice script, thanks. Took me a little while to get it working but once I found out why it wasn't it was great, which is more than I can say for the other similar scripts I found online. Now I just have to tweak the settings to get it to match the rest of my site. :)A couple of things:script type="text/javascript" src="/AJAX/ajax.js"This contradicts what you write in the text about placing the ajax.js script into a directory named js. You also have a leading /. Once I changed this line to src="js/ajax.js" it worked fine.I also have problems with scripts like this that use standard tags such as body and header that will almost certainly be already used on websites. Might just be me, but I think that scripts should keep their tags unique, jdabody and jdaheader for instance in this case.Minor quibbles though. Thanks again.

ibrahim at 04:48PM, 2011/07/05.
sorry, i mean thanks dave you're right, the code must be script type="text/javascript" src="js/ajax.js not script type="text/javascript" src="/AJAX/ajax.js

Marcos,Unfortunately, Ajax does not support loading of external URL's if that's what you ask for. If you want to support loading of external url's via ajax, you need to implement some sort of server side routine which fetch the page from the remote server and sends the content from your server to the browser.Alex,If you change the selectArticle function to the code below, you can add this at the bottom of your html page:<script type="text/javascript">selectArticle('article1.html');</script>............function selectArticle(article) // User have clicked on an article{ if(!article){ article = this.id + '.html'; } getAjaxFile(article ); // Calling the getAjasFile function. argument to the function is id of this <li> + '.html', example "article1.html" if(clickedArticle && clickedArticle!=this)clickedArticle.className='articleMouseOver'; this.className='articleClick'; clickedArticle = this;}

Hi first of all fantastic site, I love you man! (in a heterosexual way). Aaaanyway yeah I want to add a lot of articles, how easy would it be to have them all within a subfolder? What would I need to change in the code? Any help is much appreciated!
Luke at 01:09PM, 2012/04/26.
^ignore that, I got it. changegetAjaxFile(this.id + '.html');togetAjaxFile('nameoffolder/' + this.id + '.html');and put the files in a subfolder (in this case called nameoffolder but rename it whatever you want)
Luke at 01:58PM, 2012/04/26.
This doesnt work. The articles will not load. I have put them in the same directory as the index file and it just says "finding article"
