I tried this method – no joy.

Any ideas where I’m messing up? Thanks.

I’m trying to pass the variable ‘url’ down to the next function.

function getData(url) { var datatosend=”graphrequest=graphcounter1″; var req = new XMLHttpRequest(); req.open(“POST”, url, true); req.onreadystatechange = function(url) { return function() { document.getElementById(“zone1″).innerHTML = “0″; if(req.readyState == 4 && req.status == 200) { document.getElementById(“zone1″).innerHTML = req.responseText;
setTimeout(“getData(url)”, 3000); //refresh rate for graph (ms) } }(url); };
req.setRequestHeader(“Content-Type”, “application/x-www-form-urlencoded”); req.send(datatosend); }
