getting data but unable to save it ajax

This is my code for a service
function usersClicked() {
var response;
$.ajax({
url: 'somedomain.com/get_users',
type: 'GET',
dataType: 'jsonp',
crossDomain: true,
contentType: "application/json; charset=utf-8",
success: function (data, status, xhr) {
alert(data);
}
});
}
In network tab, I am able to see the response but it is unable to alert data. No dialog is being shown. can anyone help me with this
Response Header

Ajax error value return null

I have a function in ajax :
$.ajax({
type: "POST",
url: "#Url.Action("FiltraLevatamento", "Consulta")",
data: JSON.stringify(jsn),
contentType: "application/json",
dataType: "json",
async: true,
success: function (data) {
result(data);
$("#modalboxProcessa").modal("hide");
},
error: function (XMLHttpRequest, txtStatus, errorThrown) {
$("#modalboxProcessa").modal("hide");
$("#modalboxErro2").modal("show");
}
});
In my local machine works properly only when I publish in the server error in ajax .
Can anyone tell me what is the problem ? I have pretty much the same ajax only returning me other than data, and is running fine .

Make AJAX post call with data

This is in my default.aspx
$.ajax({
url: "Default.aspx/Myfunction",
dataType: "json",
type: "POST",
data: {someParameter: "some value"},
contentType: "application/json; charset=utf-8",
success: function (data) {
alert(data.d);
},
error: function (d) {
alert("error");
}
});
And this is in my codebehind:
[WebMethod]
public static string Myfunction(string someParameter)
{
return "hello";
}
It keeps going to the error. I see that if I send the Ajax request with null for data and no parameters on the function I get the data "hello" out. So there is some issue in how I send the data, but it is unclear what

Put your parameters in quotes
$.ajax({
url: "Default.aspx/Myfunction",
dataType: "json",
type: "POST",
data: {'someParameter': 'some value'},
contentType: "application/json; charset=utf-8",
success: function (data) {
alert(data.d);
},
error: function (d) {
alert("error");
}
});

Data object must be a single string.
data: JSON.stringify({someParameter: "some value"})

Change this line:
data: {someParameter: "some value"},
to:
data: {"someParameter": "some value"},
JSON object properties needs to be enclosed with quotes.

Here is how I do the same thing:
$.ajax({
type: "POST",
dataType: "json",
url: "RouteService.asmx/getRouteData",
data: { techID: techID, jobID: jobID },
success: function(msg) {
processRouteData(msg);
}
Try removing this line:
contentType: "application/json; charset=utf-8",

$ajax method does not execute for external javascript

very stupidly question I think, When I put this code inline then works, but when I put it on external js file it can not debug after the $ajax method.
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: 'WebService/Common/Bank.asmx/GetBank',
data: "{}",
dataType: "json",
async: false,
success: function (data) {
debugger; ///debug point not reach here
$.each(data.d, function (key, value) {
$("#ddlLCMasterBank").append($("<option></option>").val(value.BankID1).html(value.BankName1));
});
},
error: function (result) {
alert("Error");
}
});

Sending string to wcf service using jquery ajax. why can i only send strings of numbers?

For some reason, I'm only able to pass strings containing numbers to my web service when using jquery ajax. This hasn't been an issue so far because I was always just passing IDs to my wcf service. But I'm trying to do something more complex now but I can't figure it out.
In my interface:
[OperationContract]
[WebInvoke(ResponseFormat = WebMessageFormat.Json)]
DataTableOutput GetDataTableOutput(string json);
My webservice:
public DataTableOutput GetDataTableOutput(string json)
{
DataTableOutput x = new DataTableOutput();
x.iTotalDisplayRecords = 9;
x.iTotalRecords = 50;
x.sColumns = "1";
x.sEcho = "1";
x.aaData = null;
return x;
}
Javascript/Jquery:
var x = "1";
$.ajax({
type: "POST",
async: false,
url: "Services/Service1.svc/GetDataTableOutput",
contentType: "application/json; charset=utf-8",
data: x,
dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
The above code WORKS perfectly. But when I change x to "t" or even to "{'test':'test'}" I get a Error 400 Bad Request error in Firebug.
Thanks,
John
EDIT:
Making some progress!
data: JSON.stringify("{'test':'test'}"),
Sends the string to my function!
EDIT2:
var jsonAOData = JSON.stringify(aoData);
$.ajax({
type: "POST",
async: false,
url: sSource,
contentType: "application/json; charset=utf-8",
data: "{'Input':" + jsonAOData + "}",
dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
EDIT3: I modified the code block I put in EDIT2 up above.
Swapping the " and ' did the trick!
$.ajax({
type: "POST",
async: false,
url: sSource,
contentType: "application/json; charset=utf-8",
data: '{"Input":' + jsonAOData + '}',
dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
However, I have a new problem:
public DataTableOutput GetDataTableOutput(DataTableInputOverview Input)
{
The input here is completely null. The values I passed from jsonAOData didn't get assigned to the DataTableInputOverview Input variable. :(

I modified the code block I put in EDIT2 up above.
Swapping the " and ' did the trick!
$.ajax({
type: "POST",
async: false,
url: sSource,
contentType: "application/json; charset=utf-8",
data: '{"Input":' + jsonAOData + '}',
dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
This actually worked but I had to fix the format of the object I was sending to GetDataTableOutputOverview
