Here is my code:

function evalCtr(Ctr)
{
var xxxhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xxxhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xxxhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xxxhttp.onreadystatechange=function()
  {
  if (xxxhttp.readyState==4 && xxxhttp.status==200)
    {
    alert(xxxhttp.responseText);
    }
  }
var params = "oper=XXX&Center=YYY";
xxxhttp.open("post","c_ctr.cfm",true);
xxxhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xxxhttp.setRequestHeader("Content-length", params.length)
xxxhttp.setRequestHeader("Connection", "close");

xxxhttp.send(params);
}
Here is my code:<br /> <br /> <pre><nowiki>function evalCtr(Ctr) { var xxxhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xxxhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xxxhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xxxhttp.onreadystatechange=function() { if (xxxhttp.readyState==4 && xxxhttp.status==200) { alert(xxxhttp.responseText);   } } var params = "oper=XXX&Center=YYY"; xxxhttp.open("post","c_ctr.cfm",true); xxxhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded"); xxxhttp.setRequestHeader("Content-length", params.length) xxxhttp.setRequestHeader("Connection", "close"); xxxhttp.send(params); }</nowiki></pre>
