Core AJAX example using XMLDOM and XMLHttpRequest ActiveX Objects

Javascript:

function GetEmpDetails(obj)
{
if(obj.value!='')
{
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
var xmlHttp=new ActiveXObject('Msxml2.XMLHTTP')
xmlHttp.open('GET','ServerPage.aspx?empid=' + obj.value ,false);
xmlHttp.send(null)
//alert(xmlHttp.responseText);
xmlDoc.loadXML(xmlHttp.responseText)
var result = xmlDoc.getElementsByTagName('result');

if(result[0].text==1)
{
var EmpFirstName = xmlDoc.getElementsByTagName('EmpFirstName');
var EmpPreferredFirstName = xmlDoc.getElementsByTagName('EmpPreferredFirstName');
var EmpLastName = xmlDoc.getElementsByTagName('EmpLastName');
var EmpPhoneNum = xmlDoc.getElementsByTagName('EmpPhoneNum');
