I am learing using jquery ajax to hander the JSON..i writre a demo code.
HTMLCODE
$(function () {
$("#add").click(function () {
var json = '{ "str":[{"Role_ID":"2","Customer_ID":"155","Brands":"Chloe;","Country_ID":"96;"}]}';
$.ajax({
url: "func.aspx/GetJson",
type: "POST",
contentType: "application/json",
dataType: 'json',
data: json,
success: function (result) {
alert(result);
},
error: function () {
alert("error");
}
});
});
});
<div>
<input type="button" value="add" id="add" />
</div>
i got a input and bind a script function to it, now the proble is comeing..
my C# functiong like that.
[WebMethod]
public static string GetJson(object str)
{
return str.ToString();//good for work
}
[Serializable]
public class TestClass
{
public TestClass()
{
}
public TestClass(string role_id, string customer_id, string brands, string countryid)
{
this.Role_ID = role_id;
this.Customer_ID = customer_id;
this.Brands = brands;
this.Country_ID = countryid;
}
public string Role_ID { get; set; }
public string Customer_ID { get; set; }
public string Brands { get; set; }
public string Country_ID { get; set; }
}
when i user
public static string GetJson(object str)
everything is so good.~~ no error at all
but . when i try to use my own class TestClass.
firebug tell me that
"Type 'TestClass' is not supported for deserialization of an array."
.any body can give me help:XD
This is how it looks when I do this using a WCF webservice. Hopefully it can help you. Let me know if you need any further clarification.
Script:
var data = {
emailAddress: emailAddress,
firstName: firstName,
lastName: lastName,
groups: groups
};
$.ajax({
type: "POST",
url: Client.svc/Subscribe",
data: JSON.stringify(data),
dataType: "json",
contentType: "application/json; charset=utf-8",
processdata: true,
success: function (result) {
//do something
}
});
Service:
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[BasicHttpBindingServiceMetadataExchangeEndpoint]
public class Client : IClient
{
public bool Subscribe(string emailAddress, string firstName, string lastName, string[] groups)
{
//do something
return true;
}

I am having a hard time posting a list of arrays from my view to the controller. Every other value is coming through.
Can someone spot what is wrong with my code?
Controller:
public ActionResult SaveProgress(BBCRMSurveyVM model)
{
try
{
return Json(new { success = true });
}
catch (Exception e)
{
return Json(new { success = false, msg = e.Message });
}
}
Main view model:
public string ImplementationProcessFeelWasSuccessful { get; set; }
public string ImplementationProcessAdviceOtherFederations { get; set; }
public List<AdditionalTechnologyVM> AdditionalTech = new List<AdditionalTechnologyVM>();
AdditionalTechVM:
public class AdditionalTechnologyVM
{
public string PlatformName { get; set; }
public string BusinessPurpose { get; set; }
public bool? FullyIntergrated { get; set; }
public bool? PartiallyIntergrated { get; set; }
}
JS file:
function onAddButtonClickEvent() {
additionaltechs.push({
'PlatformName': platformNameAT,
'BusinessPurpose': businessPurposeAT,
'FullyIntergrated': intergrated == "Fully" ? true : false,
'PartiallyIntergrated': intergrated == "Partially" ? true : false
});
}
function SaveProgress() {
var formData = $('#wizard').serializeArray();
//if (additionaltechs.length > 0) {
// for (var x = 0; x < additionaltechs.length; x++) {
// formData[formData.length] = { name: "AdditionalTech", value: JSON.stringify(additionaltechs[x]) };
// }
//}
formData[formData.length] = { name: "AdditionalTech", value: additionaltechs };
$.each(formData, function (index, field) {
if (field.name.search('Budget') > 0) {
field.value = field.value.replace('$', '').replace(/,/g, '');
}
});
formData = JSON.stringify(formData);
console.log(formData);
$.ajax({
url: '/save-progress',
contentType: 'application/json; charset=utf-8',
type: 'POST',
data: formData,
dataType: 'json',
success: function () {},
error: function () {}
});
}
The output in the console:
The list count is always 0?
I think you made this more complicated than you needed it to be. :)
Ultimately, it looks like your controller method is taking a single model, not an array. Thus, I would suspect to see the JSON you send look like this:
{
"ImplementationProcessFeelWasSuccessful" : "",
"ImplementationProcessAdviceOtherFederations" : "",
"AdditionalTech" : [...]
}
If it should be a single item being sent, then I'd expect your code to be like this:
function SaveProgress() {
var formData =
{
ImplementationProcessFeelWasSuccessful : $('#wizard #val1').val(),
ImplementationProcessAdviceOtherFederations : $('#wizard #val2').val(),
AdditionalTech : additionaltechs
};
formData = JSON.stringify(formData);
console.log(formData);
$.ajax({
url: '/save-progress',
contentType: 'application/json; charset=utf-8',
type: 'POST',
data: formData,
dataType: 'json',
success: function () {},
error: function () {}
});
}
However, you are sending an array of items up and that makes no sense here.
Ended up sending the list as a JSON string & receiving it also as a string. In the controller I using the JsonConvert.DeserializeObject method like this:
var additionalTechs = JsonConvert.DeserializeObject<List<AdditionalTechnologyVM>>
(model.AdditionalTech);
Im tring to post FormData values to controller. Its success on POST method but i want to get returned values. I tried get but dont work. I added too many argument but dont work. Can u help me ?
jquery/ajax
var Data = new FormData();
Data.append('yparca', yparca);
Data.append('mekanik', mekanik);
//more values
$.each($("#img_upload_" + id)[0].files, function (i, file) {
Data.append('resimler', file);
});
$.ajax({
url: "/Sections/AddRowsToMarketPart",
type: 'GET',
data: Data,
processData: false,
contentType: "application/json; charset=utf-8",
dataType:'json',
success: function (data) {
alert("success");
Toast.fire({
icon: 'success',
title: 'Parça sepete eklendi.'
})
}
Controller
[HttpGet]
public JsonResult AddRowsToMarketPart(SubPart2Val model)
{
//Do something AND RETURN A VALUE
return Json(model);
}
Class
public class SubPart2Val
{
public int id { get; set; }
public string yparca { get; set; }
public string mekanik { get; set; }
//some properties
public List<IFormFile> resimler { get; set; }
}
Your content type is incorrect, you set it as json when it's form data.
To have it set properly in $.ajax set contenType to false
Also you cant sent form data with a GET request use POST
$.ajax({
url: "/Sections/AddRowsToMarketPart",
type: 'POST',
data: Data,
processData: false,
contentType: false,
dataType:'json',
...
[HttpPost]
public JsonResult AddRowsToMarketPart(SubPart2Val model)
{
//Do something AND RETURN A VALUE
return Json(model);
}
have tried the methods found but still cannot seem to tackle the issue.
am passing a list of object via Jquery Aja but it seems that the controller is receiving null values (it is recognizing the list count fine).
the jquery code is as follows:
var xmlids = Array();
for (var i = 0; i < orderId.length; i++) {
var xdata = {
"XmlOid": "" +orderId[i] + "",
"CourierCompany": $("#CourierCompany_"+orderId[i]).val() ,
"CourierService": $("#CourierService_" + orderId[i]).val(),
"StoreId" : storeId
};
xmlids.push(xdata);
}
var data = { invoices: xmlids };
$.ajax({
url: purl,
type: "POST",
dataType: "json",
//contentType: "application/json;",
async: false,
data: data,
The controller param is :
public JsonResult ProcessSaleOrder(List<XMLInvoiceGeneration> invoices)
the object is as follows:
public class XMLInvoiceGeneration
{
public Int64 XmlOid { get; set; }
public string CourierCompany { get; set; }
public string CourierService { get; set; }
public Int64? StoreId { get; set; }
}
any help appreciated.
I tried to replicate your problem.
I created a new ASP.NET MVC web application, and in the Home controller's Index view, I added the following
<input type="button" id="send" value="Send" />
#section scripts{
<script type="text/javascript">
$(function () {
$("input#send").on("click", function () {
var xmlids = Array();
for (var i = 0; i < 2; i++) {
var xdata = {
"XmlOid": 1,
"CourierCompany": "TempData",
"CourierService": "Temp",
"StoreId": 2
};
xmlids.push(xdata);
}
var data = { invoices: xmlids };
$.ajax({
url: "/Home/ProcessSaleOrder",
type: "POST",
dataType: "json",
async: false,
data: data
});
});
})
</script>
}
I basically created some temp data, but trying to still use your original idea. My controller looks like this:
[HttpPost]
public ActionResult ProcessSaleOrder(List<XMLInvoiceGeneration> invoices)
{
return new EmptyResult();
}
When I click the button, and hit the breakpoint in the controller, the invoices parameter contains 2 items, both with the values I set in the JavaScript code. I'm not sure why your code isn't working, but maybe you can use mine as a template to help you narrow down what the issue is.
Try this
uncomment //contentType: "application/json;",
And send data with JSON.stringify(data)
data: JSON.stringify(data)
PS: Best practice for url : url: "#Url.Action("method","controller")"
I had the same issue on sending a List to the controller. After a lot of effort, I found the reason why it is sending as null. It's the fields with Return Type(Class) that are not added with {get; set; }
$.ajax({
url: "/Home/CreateTasks",
data: ko.toJSON({Id: this.Id, tasks: objList }),
type: "POST",
dataType: "json",
processData: true,
contentType: "application/json; charset=utf-8",
success: data => {
}
And my Model Class is:
After
public class TaskFields
{
public string Title { get; set; }
public string Activity { get; set; }
}
public class CreateTaskInput
{
public int Id { get; set; }
public TaskFields TaskProperties { get; set; }
}
Before it was:
public class TaskFields
{
public string Title;
public string Activity;
}
public class CreateTaskInput
{
public int Id;
public TaskFields TaskProperties;
}
And My Controller Method is:
[HttpPost]
public JsonResult MethodName(int Id, List<CreateTaskInput> tasks)
{
}
I am not sure this answer will help you. But it may help someone who has a similar mistake. Thanks!
Add [FromBody] to the parameters in action
[HttpPost]
public ActionResult ProcessSaleOrder([FromBody] List<XMLInvoiceGeneration> invoices)
{
return new EmptyResult();
}
Writing a web api project and one of the parameters (which is a json array) on my method is coming into the api null. The jquery I'm making the call with looks like this:
<script>
$(document).ready(function () {
$('#btnSubmit').click(function () {
var jsRequestAction = {
appId: 'appName',
custId: 'custId',
oprId: 'oprId',
businessProcess: 'Requisition',
action: 'Approve',
actionKeys: [
'blah blah 1',
'blah blah 2',
'blah blah 3'
]
};
$.ajax({
type: "POST",
content: "json",
url: "http://localhost/api/appName/custId/oprId",
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ requestAction: jsRequestAction })
});
});
});
</script>
My web api method looks like this:
public IList<ResponseAction> ActionCounter(string appName, string custCode, string custUserName, RequestAction requestAction)
{
IList<ResponseAction> actionResponseList = new List<ResponseAction>();
var conn = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);
conn.Open();
try
{
foreach (string s in requestAction.actionKeys)
{
var command = new SqlCommand
{
CommandText = "Sql statement",
Connection = conn
};
command.ExecuteNonQuery();
var reply = new ResponseAction();
reply.responseActionKey = s;
reply.responseMessage = "Success";
actionResponseList.Add(reply);
}
return actionResponseList;
}
finally
{
conn.Close();
conn.Dispose();
}
}
RequestAction model:
public class RequestAction
{
public string appId { get; set; }
public string custId { get; set; }
public string oprId { get; set; }
public string businessProcess { get; set; }
public string action { get; set; }
public string[] actionKeys { get; set; }
public string actionKey { get; set; }
}
When I debug, I step through the method and when I get to the foreach loop, I get a null object reference. Looking in my locals section, all my properties for requestAction are null. I have tried prefixing the object with the [FromBody] tag to no avail after reading a few related articles. Any help would be appreciated.
I found the answer to my question HERE. It was a matter of changing this:
$.ajax({
type: "POST",
content: "json",
url: "http://localhost/api/appName/custId/oprId",
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ requestAction: jsRequestAction })
});
to this:
$.ajax({
type: "POST",
content: "json",
url: "http://localhost/api/appName/custId/oprId",
data: jsRequestAction
});
Otherwise, the data won't bind to my model in the controller and everything will be nulled out.
You need to make sure the object server side matches the object you are creating client side so that the request can be serialized directly into the object.
So your action method will look like this:
public IList<ResponseAction> ActionCounter(RequestAction requestAction)
{
// Do stuff
}
Where RequestAction should match the javascript object you are creating.
This is my model
Model
public class XPersonContent
{
public string PersonType { get; set; }
public int PersonId { get; set; }
}
public class XViewModel
{
public List<XPersonContent> XPersonList { get; set; }
public string XContent { get; set; }
public sbyte CommentEnabled { get; set; }
}
Controller
[HttpPost]
public JsonResult AddXViewModel ( XViewModel testModel)
{
}
Form using MVC that submits to controller
function submitForm() {
var xpersonContent=[Object { Id=2934109, Type="us"}, Object { Id=2913974, Type="us"}, Object {Id=2912159, Type="us"}]
var xContent= "test";
var CommentEnabled= false;
var dataString = {
XPersonList:xpersonContent,
XContent: xContent,

};
$.ajax({
type: "POST",

success: function (data) {
$("#ajaxPostMessage").empty();
$("#ajaxPostMessage").html(data.Message + " : " + data.Date);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {

});
}
> Question
How do i build the object XViewModel to pass back to the controller. i have them in three different variables
i have tried to do this
dataString = {
XPersonList:xpersonContent,
XContent: xContent,
CommentEnabled: true
};
but its not working..
I had to add
contentType: "application/json; charset=utf-8",
in my ajax request
SMH
Try change to this
var xpersonContent=[{"XPersonContent": {"Id": 2934109, "Type": "us"}}, {"XPersonContent": {"Id": 2913974, "Type": "us"}}, {"XPersonContent": {"Id": 2912159, "Type": "us"}}]
