JQuery/AJAX registration

Question

 function reg(email, pass){
 $.ajax({
 url: "uman.php",
 type: "post",
 data:{email: email, password: pass},
 success: function(reply){
 if (reply == "success"){
 $("#signinup").hide();
 $("#donesucc").css("display","block");
 console.log(reply);
 }
 if (reply == "duplicate"){
 $("#signinup").hide();
 $("#donedupe").css("display","block");
 }
 }
 })
 }

Anything I should change? The PHP just echos the status of the query and Javascript takes that value and outputs the results through HTML.

What do you think about this?

var Request = {
 version: 1.0, //not needed but i like versioning things
 xproxy: function(type, url, data, callback, timeout, headers, contentType) 
 {
 if (!timeout || timeout <= 0) { timeout = 15000; }
 $.ajax(
 {
 url: url,
 type: type,
 data: data,
 timeout: timeout,
 contentType: contentType,
 success:function(data) 
 {
 if (callback != undefined) { callback(data); }
 },
 error:function(data) 
 {
 if (callback != undefined) { callback(data); }
 }, 
 beforeSend: function(xhr)
 {
 //headers is a list with two items
 if(headers)
 {
 xhr.setRequestHeader('secret-key', headers[0]);
 xhr.setRequestHeader('api-key', headers[1]);
 }
 }
 });
 }
};
<script type="text/javascript">
var contentType = "applicaiton/json";
var url = "http://api.lastfm.com/get/data/";
var timeout = 1000*5; //five seconds
var requestType = "POST"; //GET, POST, DELETE, PUT
var header = [];
header.push("unique-guid");
header.push("23903820983");
var data = "{\"username\":\"james\"}"; //you should really deserialize this w/ a function
function callback(data)
{
 //do logic here
}
Request.xproxy(requestType, url, data, callback, timeout, header, contentType);
</script>
