请在Ajax中等待消息

Question

I am little new in ajax and js. I am trying to send the data to functions.php?action=signp but the code says "please wait" and then nothing happens. My code is given below:

<script type="text/javascript">
function signup()
{
    var ufname = document.getElementById("fName").value;
    var ulname = document.getElementById("lName").value;
    var e = document.getElementById("email").value;
    var p1 = document.getElementById("pass1").value;
    var p2 = document.getElementById("pass2").value;
    var status = document.getElementById("statusSignUp");
    if(ufname == "" || ulname == "" || e == "" || p1 == "" || p2 == "")
    {
        status.innerHTML = "Fill out all of the form data";
    }
    else
    {
        document.getElementById("signupbtn").style.display = "none";
        status.innerHTML = 'please wait ...';
        var ajax = ajaxObj("POST", "functions.php?action=signp");
        ajax.onreadystatechange = function()
        {
            if(ajaxReturn(ajax) == true)
            {
                if(ajax.responseText != "signup_success")
                {
                    status.innerHTML = ajax.responseText;
                    document.getElementById("signupbtn").style.display = "block";
                } 
                else
                {
                    window.scrollTo(0,0);
                    document.getElementById("signupform").innerHTML = "Yippieeee";
                }
            }
        }
        //xhttp.open("POST", "functions.php?action=signp", true);
        ajax.send("&fName="+fName+"&lName="+lName+"&email="+email+" pass1="+pass1);
    }
}
</script>

Someone please tell me is there anything wrong in the code?

I would give you a very easy solution for this. Use jQuery Ajax. Its a very easy library to use.
