files in the same server. for some reason it does not work?? i have no
clue as i am new to ajax.

<h2>ajax jquery</h2>
<ul id="navigation">

<li><a href="#page2">Page2</a></li>
<li><a href="#page3">Page_3</a></li>
<li><a href="#page4">Page_4</a></li>

</div><div class="clear"></div>
<img src="img/bottom_bg.gif" alt="bottom" /></div>
</body>
</html>
script.js(for adding hash in the url and enable back button and also
loading content)
var default_content="";
$(document).ready(function(){
checkURL();
$('ul li a').click(function (e){
checkURL(this.hash);
});
default_content = $('#pageContent').html();
setInterval("checkURL()",250);
});
var lasturl="";
function checkURL(hash)
{
if(!hash) hash=window.location.hash;
if(hash != lasturl)
{
lasturl=hash;
if(hash=="")
$('#pageContent').html(default_content);
else
loadPage(hash);
}
}
function loadPage(url)
{
var datastring=url.replace('#','');
$('#loading').css('visibility','visible');
$.ajax({
type: "POST",
url: "load_page.php",
data: 'datastring='+datastring,
dataType: "html",
async: false,
success: function(msg){
if(parseInt(msg)!=0)
{
$('#content').html(msg);
$('#loading').css('visibility','hidden');
}
}
});
}
and load_page.php
<?php
$url = $_REQUEST['datastring'];
echo $url;
if(file_exists(''.$url.'.html')){
echo file_get_contents(''.$url.'.html');
}
else{
echo 'There is no such page!';
}
?>
need help! as you can see when the ajax calls the "pagecontent" div loads
the content from the requested page, but nothing happens here! what am i
doing wrong?
