Hey,

I need help big time as my site has just completly buggered up lol!

I just made a JS script which laoads data into a div (ajax style) which means page refreshes are not required... but currently it loads a $pagename.php "contents" in to the div - but i cannot have this method.

What i need it to do - is generate a string with the $pagename.php and inject that to a variable into the div... heres what i got:


This works as its meant to - but needs to be changed to suit my new method:


var bustcachevar=1 //bust potential caching of external pages after initial request? (1=yes, 0=no)
var loadedobjects=""
var rootdomain="http://"+window.location.hostname
var bustcacheparameter=""

function ajaxpage(url, containerid){
var page_request = false
if (window.XMLHttpRequest) // if Mozilla, Safari etc
page_request = new XMLHttpRequest()
else if (window.ActiveXObject){ // if IE
try {
page_request = new ActiveXObject("Msxml2.XMLHTTP")
}
catch (e){
try{
page_request = new ActiveXObject("Microsoft.XMLHTTP")
}
catch (e){}
}
}
else
return false
page_request.onreadystatechange=function(){
loadpage(page_request, containerid)
}
if (bustcachevar) //if bust caching of external page
bustcacheparameter=(url.indexOf("?")!=-1)? "&"+new Date().getTime() : "?"+new Date().getTime()
page_request.open('GET', url+bustcacheparameter, true)
page_request.send(null)
}

function loadpage(page_request, containerid){
if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
document.getElementById(containerid).innerHTML=page_request.responseText
}

function loadobjs(){
if (!document.getElementById)
return
for (i=0; i<arguments.length; i++){
var file=arguments[i]
var fileref=""
if (loadedobjects.indexOf(file)==-1){ //Check to see if this object has not already been added to page before proceeding
if (file.indexOf(".js")!=-1){ //If object is a js file
fileref=document.createElement('script')
fileref.setAttribute("type","text/javascript");
fileref.setAttribute("src", file);
}
else if (file.indexOf(".css")!=-1){ //If object is a css file
fileref=document.createElement("link")
fileref.setAttribute("rel", "stylesheet");
fileref.setAttribute("type", "text/css");
fileref.setAttribute("href", file);
}
}
if (fileref!=""){
document.getElementsByTagName("head").item(0).appendChild(fileref)
loadedobjects+=file+" " //Remember this object as being already added to page
}
}
}



With that and this below is how it all works on the site so far:


<a href="javascript:ajaxpage(login.php','contentarea');">Link to login</a>
<div id="contentarea"></div>



How ever i need to change this so instead of it just "loading the page contents" into the div i want the JS to do similiar idea of loading into the div but merely pass php into it so i can do this:



<a href="javascript:ajaxpage(login.php','contentarea');">Link to login</a>
<div id="contentarea">
<?php
include($name);
//$name being "login.php" due to above href
//$name value needs to be made from the JS from getting the
//url in the HREF whilst not refreshing the page to do so.
?>
</div>


Can some one help me edit my JS to do what im trying to do ? I'm stuck at this point at trying to get it to do this final part.

<a href="javascript:ajaxpage('page.php?p=login','contentarea');">Link to login</a>


page.php:



<?php
$name=$_GET['p'];

include "$name.php";
?>


Would that do it?
