var xmlhttp = createxmlhttprequestobject(); function createxmlhttprequestobject() { var xmlhttp; if(window.activexobject) { try { xmlhttp = new activexobject("microsoft.xmlhttp"); } catch(e) { xmlhttp = false; } } else if(window.xmlhttprequest) { try { xmlhttp = new xmlhttprequest(); } catch(e) { xmlhttp = false; } } if(!xmlhttp) { alert('cannot connect database!'); } else { return xmlhttp; } } function process() { if(xmlhttp.readystate == 0 || xmlhttp.readystate == 4) { food = encodeuricomponent(document.getelementbyid("userinput").value); xmlhttp.open("get", "ajax.php?food=" + food, true); xmlhttp.onreadystatechange = handleserverresponse; xmlhttp.send(null); } else { settimeout('process()',1000); } } function handleserverresponse() { if(xmlhttp.readystate == 4) { if(xmlhttp.status==200) { xmlresponse = xmlhttp.responsexml; xmldocumnetelement = xmlresponse.documentelement; message = xmldocumentelement.firstchild.data; document.getelementbyid("underinput").innerhtml = "<span style='color:blue'" + message + "</span>"; settimeout('process()',1000); } } else { alert('something went wrong'); } } everything seems fine me still keep getting error 'xmldocumentelement not defined'. seems error due parsing issues within javascript , php.. please me fix error. thanks
