Using AJAX as an iframe problem

[Cody M]

Hey all I'm currently having a problem with AJAX and PHP combined.

I currently have a site setup where I have an HTML page as a main page, and I'm using AJAX to display a PHP page within the HTML within a div (kind of like an iframe).

I'll provide the code if it helps (credits to Dynamic Drive):

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
}
}
}

 

And this is the code for links I have within the HTML page the function is on:

<a href="javascript:ajaxpage('index.php', 'contentarea');">TEST</a>

 

The index.php gets loaded into this div on the HTML page:

<div id="contentarea">INDEX.PHP LOADED HERE</div>

 

The problem is, I have links within the PHP pages that if clicked, gets rid of the HTML webpage. I would like to know how I would get links within the PHP page to load in the contentarea div.

 

This is a sample of the PHP code I'm trying to "route" to load in the div via the AJAX code:

<a class='q_link' href='town.php?town=".$towns[$i][0]."'>".$towns[$i][2]."</a>

 

Help would be much appreciated! I've been at this for quite some time now and just can't for the life of me get it to work!

 

Thanks for your time
