JS fails if url has a GET

[EchoFool]

Hey

 

I have a JS script which loads the contents of a page into a <div> which works until i start using GETs in the urls... as it doesn't process the ruls so now im stuck as to how alter the script to get it to work.. this is what i got:

 

This is the html the user iteracts with:

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

 

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(pagename, 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)
}

var url = rootdomain + "/jax.php";

if (bustcachevar) //if bust caching of external page
bustcacheparameter=(url.indexOf("?")!=-[[1]])? "&"+new Date().getTime() : "?"+new Date().getTime()
page_request.open('GET', url+bustcacheparameter + "&link=" + pagename, 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
      }
  }
}

 

This php script is called in the javascript to process the url:

 

<?php

  function getParm ($parmName)
  {
    $retParm = null;
    if(isset($_POST[$parmName]))
    {
      $retParm = $_POST[$parmName];
    }
    else
    {
      if(isset($_GET[$parmName]))
      {
    $retParm = $_GET[$parmName];
      }
    }

    return ($retParm);
  }

  $link = getParm("link");
  include($link);

?>

 

If i have gets in the html then the GETs don't get parsed through and there fore don't load, how can i solve this?
