ASP WebMethod Returns JSON Wrapped In Quotes
Jun 8, 2010
I have an asp.net page with a WebMethod on it to pass JSON back to my javascript. Bellow is the web method:
[WebMethod]
public static string getData(Dictionary<string, string> d) {
string response = "{ "firstname": "John", "lastname": "Smith" }";
return response;
}
When this is returned to the client it is formatted as follows:
{ "d": "{ "firstname": "John", "lastname": "Smith" }" }
The problem is the double quotes wrapping everything under 'd'. Is there something I've missed in the web method or some other means of returning the data without the quotes? I don't really want to be stripping it out on the client everytime. Also I've seen other articles where this doesn't happen.

Lots of people recommend to wrap the MVC JsonReturn result in a textarea to play nicely with jquery forms etc.
That part makes sense but how do I get the json object back in my client jquery code?
The client jquery plugin should look something like this:
// Doesn't work since data is "<textarea>{"error":true,"msg":"foo"}

Why does this
string test = "Text1, Text2";
string [] tests = test.Split(", ".ToArray());
returns this
[0] = "Text1"
[1] = ""
[2] = "Text2"
what's with the quotes in tests[1] ? I thought the output would be like this
[0] = "Text1"
[1] = "Text2"

System.Web.Script.Serialization.JavaScriptSerializer s = new System.Web.Script.Serialization.JavaScriptSerializer();
result = s.Deserialize<Hashtable>(data);
Error is thrown if data is "{a:""test" 123",b:"hello" }"
No error is thrown if data is "{a:"test 123",b:"hello" }"
How do I adjust the data string so that no error is thrown even when there are quotes?

I am using .Net Framework 3.5 on an ASP.net web project using jquery.ajax to make web service calls. My web service returns objects serialized as JSON by specifying the content type of my POST as "application/json". I would like just one of my many properties to return a non quoted javascript function name instead of a quoted string. Serialized as such:
{"dataInit": functionName, "id": "myID"}
instead of
{"dataInit": "functionName", "id":"myID"}

How to return values from Webmethod to the client in JSON format? There are two static int values that i want to return.Do I need to create new object with those 2 properties and return it?The GetStatus() method is called frequently and i don't like the idea of creating a special object each time just for json formatting...
[WebMethod]
public static int GetStatus()
{
int statusProcess,statusProcessTotal;
Status.Lock.EnterReadLock();
statusProcess=Status.Process; //Static field
statusProcessTotal=Status.ProcessTotal; //Static field
Status.Lock.ExitReadLock();
return ...
}
On client side I catch the return value in :
function OnSucceeded(result, userContext, methodName)
(PageMethods.GetStatus(OnSucceeded, OnFailed);)

I have the following JSON class I am intending to use to perform management calls on my database asynchronously:
<script type="text/javascript">
var CalendarManager = {
defaultOptions: {
staffcode: 0, // required
date: 0, // required
[Code]....
Basically, my question is: how do I specify optional parameters to a WebMethod when providing JSON data?
I know I can reduce the parameters down to just the required values, and then use HttpContext.Request.Params to read the values of optional paramaters, but I would have thought the way I have tried here should have worked.
EDIT
The XMLHttpRequest.responseText value for the error is:
Invalid JSON primitive: staffcode.
This is throwing me even more off the scent of the problem :(

I'm doing an jQuery AJAX POST call to a webmethod, which is working fine. If I'm passing data from the AJAX call, I normally get the data in the webmethod via webmethod parameters.
JavaScript Code:
$.ajax({"dataType": "json","contentType": "application/json","type": "POST","url": "Default.aspx/GetStuff","data": JSON.stringify({"a":"data1","b":2}),"success": function (msg) {Â Â console.log(msg.d);}});
C# Code:
[WebMethod]public static object GetStuff(string a, int b){Â }
Is there any way I can get the data as a Dictionary or some other object, instead of having to put in individual parameters to the GetStuff() web method for each data param? It's a POST request so nothing is in Request.QueryString, and Request.Params/Request.Form doesn't contain it either.

Upon clicking a button I need to send a collection and a few other variables to server in Json form.For each value in the collection the server code (C# ) wil update those other variables in the DB.
For example there is a ‘classnumber’ collection with values (First, Second, Third, ….),other variables (‘teacher_name’ and ‘subjectname’).For each value in the ‘classnumber’ collection I need to update the ‘teacher_name’ by searching for the ‘subject_name’ in the DB.So I need to pass the ‘classnumber’ collection,’teacher_name’,’subject_name’ values to server in json form. At the moment instead of sending the ‘classnumber’ collection I am sending ‘teacher_name’,’subject_name’,’classnumber’ as variables for each value in the collection ,which requires multiple requests made to the server.
Instead of these individual requests I am wondering if there is a way to send all the data at once to server in json form?

I have the following web method , no success on return a correct Json format.
[Code]....
GetAll() return list of type "Company" POCO classes.
The web method complaint type "Company" could not cast to object. However I could not just return the Company type because client side Json only accept its 2 properties -"CompanyName", "ID" and I want to keep it that way.
Of cause, I had tried create a CompanyDTO which only have those two properties, but same error - "Unable to cast object of type..."
How should I modify in my web method to make it able to return a list of partial "Company" type in Json format?

I am working on a mvc project, and having problem with json. i have created a demo project with list of colors
public JsonResult GetResult()
{
List<string> strList = new List<string>();
strList.Add("white");
strList.Add("blue");
strList.Add("black");
strList.Add("red");
strList.Add("orange");
strList.Add("green");
return this.Json(strList);
}
i am able to get these on my page, but when i try to delete one color, that is when i send the following using jquery
function deleteItem(item) {
$.ajax({
type: "POST",
url: "/Home/Delete/white",
data: "{}",
contentType: "application/json; charset=utf-8",
success: ajaxCallSucceed,
dataType: "json",
failure: ajaxCallFailed
});
}
the controler action public JsonResult Delete(string Color) {} Color always returns null, even if i have specified "/Home/Delete/white" in the url. i know i am doing something wrong or missing something, but not able to find out what.

I have a Page that expects a POST Request and returns some JSON. Essentially it's an .ashx Page, but that doesn't really matter.
When using jQuery, I would use jQuery.Post with "json" as dataType to simply make the POST request and get an object back. However, for the current project I mainly use ASP.net AJAX and I don't want to add jQuery just for the call.
For ASP.net AJAX, I only found information on how to call a "traditional" web service though, which means adding a asp:ServiceReference to the ScriptManager and having a "real" Web Service at the end.
Is there a simpler way to make a POST call to a Page? I could live with getting the raw JSON and then manually eval()ing it, but I don't want to create a full asmx web service (deploying them on SharePoint is a bit painful, and my ashx handler works fine)

I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).
[Code]....

As you know froms could lead to accessbility issues and unlike PHP when I was dealing with it, everything in ASP.NET we can say is wrapped inside a form. As you know not every elements is a form element and from accessbility point of view the screen readers have what is called 'forms mode' which only interact with form elements. Can anyone calrify why is that in ASP.NET?
