I'm attempting to do some AJAX and need to know why this code isn't firing a completed or error alert. I'm in Mozilla Firefox 20.0.1
PLEASE NOTE
This code IS updating the database (I have a select statement reading the exact record verifying it's updating) I'm just unsure as to why I can't get an alert when the response has completed.
I have these GLOBAL (at the top of the javascript page) declared variables.
var AjaxEnginePage;
var ClientInfoPage;
var XMLHTTP;
AjaxEnginePage = AjaxEngine.aspx;
ClientInfoPage=getClientInfo.aspx;
Creating the connection.
//Creating and setting the instance of appropriate XMLHTTP Request object to a “XmlHttp” variable
function CreateXMLHTTP()
{
try
{
XMLHTTP = new ActiveXObject(Msxml2.XMLHTTP);
}
catch(e)
{
try
{
XMLHTTP = new ActiveXObject(Microsoft.XMLHTTP);
}
catch(oc)
{
XMLHTTP = null;
}
}
//Creating object in Mozilla and Safari
if(!XMLHTTP && typeof XMLHttpRequest != undefined)
{
XMLHTTP = new XMLHttpRequest();
}
}
Tying the connection:
function btnUpdateMe_OnClick() {
var me = encodeURIComponent(document.getElementById(MeTextBox).value);
// construct the URL
var requestUrl = AjaxEnginePage + ?Action=UpdateMe&Me= + me;
CreateXMLHTTP();
// If browser supports XMLHTTPRequest object
if(XMLHTTP)
{
//Setting the event handler for the response
XMLHTTP.onreadystatechange = handleStateChange(me);
//Initializes the request object with GET (METHOD of posting),
//Request URL and sets the request as asynchronous.
XMLHTTP.open(get, requestUrl, true);
//Sends the request to server
XMLHTTP.send(null);
}
Handle State Change
function handleStateChange(me) {
switch (XMLHTTP.readyState) {
case 0: // UNINITIALIZED
case 1: // LOADING
case 2: // LOADED
case 3: // INTERACTIVE
break;
case 4: // COMPLETED
alert(Success);
break;
default: alert(error);
}
I can provide more code if needed. :( thanks.
