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,

function showUser(str)

url=url+"&sid="+Math.random()
xmlHttp.onreadystatechange=stateChanged
xmlHttp.open("GET",url,true)
xmlHttp.send(null)}function stateChanged()
