How do I take a querystring variable from a link and pass it to the
following code (function shown below)?

For example, concatenating the 77 from 'myfile.php?uniqueid=77' with
the string 'id' to get

if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("id77").innerHTML=xmlHttp.responseText
}

Many thanks,

Chris

var xmlHttp

function showUser(str)
{
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request")
return
}
var url="/~jonanna/ajax/getuser.php"
url=url+"?q="+str
url=url+"&sid="+Math.random()
xmlHttp.onreadystatechange=stateChanged
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("txtHint").innerHTML=xmlHttp.responseText
}
}function GetXmlHttpObject()
{
var xmlHttp=null;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
//Internet Explorer
try
 {
 xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
 }
catch (e)
 {
 xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
 }
}
return xmlHttp;
}
