Do I need to serialize my object in some way before setting the 'data' attribute, so that I can call $.ajax() function?

i want to get data from my database and dispaly it in my web page using json with webservicei'm going to post my code i create a webservice and add method which return string to get all data so my code like this
[Code]....
and in my page
[Code]....
I have been trying for two months to get this code working, and I am close, but still confused. I want the JQuery UI Autocomplete function to call an web service which returns JSON data and display that data for selection, and on selection put the selected value into a hidden field.
There are several issues:
1) The autocomplete function is not firing
2) The source: "/AutoSuggest.asmx/DOTFind?" line throws an invalid object exception
3) The service requires two parameters: (string prefixText, int count) - count tells it how many records to return.
4) I am not at all certain that this code will accept JSON data that comes back from the service
Here is the code:
[code]....
I have a webservice which retrieves data from another external service. The data is already in JSON Format. So I retrieve it and set it to the return value (type: string) of my webservice. But according to firebug the webservice then encapsulates the provided JSON-Data with a backslash, e.g. it returns:
[Code]....
instead of
[Code]....
But the JSON provided by the external service is correct. So how could I provide the correct string to jTemplate from my Webservice?
I have an ASP.NET webservice method that returns a generics list (List'<'Construct>) serialized as JSON, using code such as this:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class TestService : System.Web.Services.WebService {
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string GetOccupationListJSON(int SOCLevel)
{
Construct NewConstructList = new ConstructList();
DataContractJsonSerializer serializer = new DataContractJsonSerializer(ConstructList.GetType());
MemoryStream ms = new MemoryStream();
[Code]....
I assumed (from looking elsewhere) that accessing the JSON data through the index would provide me with access to the underlying object at that index, so that I can then work with it to access its properties.
However, when i=0 and I do var Construct = data[i]; I get the character at the i position of the data array ([), and in the next iteration I get the second character ({). So clearly I am accessing the elements of a string array rather than the JSON data object.How do I make sure that the data returned by the webservice gets into proper JSON format, so that I can iterate through the object elements within it?
i am using combination of jquery and JSON based webservice in most of projets. Lately i am facing this problem. if the data returned from webservice is huge ajax call from jquery fails. yup i know i can implement paging etc etc but is there a way i can increase the limit to get more data from webservice with jquery ajax call?

I've been following tutorials. I got a problem while attempting to try your sample,
Here is the sql syntax that i emulated from one of your tutorials
USE [arrestedpersonsdb]GO/****** Object: StoredProcedure [dbo].[stnencodedtodisplay]
Script Date: 08/10/2013 15:57:50 ******/SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGO-- =============================================--
Author: <Author,,Name>-- Create date: <Create Date,,>--
Description: <Description,,>-- =============================================
CREATE PROCEDURE [dbo].[stnencodedtodisplay]
( @PageIndex INT = 1 ,@PageSize INT = 10 ,@RecordCount INT OUTPUT ,@id int ,
[Code] ....
If I use the first two parameter namely stnid and type it returns as expexted but when i try to add another parameter sample below:
USE [arrestedpersonsdb]GO
DECLARE @return_value int, @RecordCount int
EXEC @return_value = [dbo].[stnencodedtodisplay] @PageIndex = 1, @PageSize = 10, @RecordCount = @RecordCount OUTPUT, @id = 1599, @fname = 'ALDRIN', @lname = ''
SELECT @RecordCount as N'@RecordCount'
SELECT 'Return Value' = @return_value
GO
it doesn't return anything is it because the data being returned is a single row or this type of query doesn't allow multiple parameters...
I try like this...
<script type="text/javascript" src="Scripts/jquery.min.js"></script>

like above link i want to bind
name.....................

I am using jquery fullcalender..
I want to bind Events to each days of the calender dynamically from the json return by the ajax method..
client code:
<script src="../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript">
$("#send").click(function () {
$.ajax({
url: "../JqueryAjax/JqueryAjaxServer.aspx",
type: 'get',
contentType: "application/json; charset=utf-8",
dataType: "json",
timeout: 30000,
data: "{}",
success: function (data, textStatus) {
alert("success");
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("error");
alert(textStatus);
alert(errorThrown.toString());
}
});
});

var record = $("[id$='record']");

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) { console.log(msg.d);}});
C# Code:
[WebMethod]public static object GetStuff(string a, int b){ }
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.
As it is now I create a JavaScript object and then stringify it, put it in a hidden textbox and my code behind can read this string. I then use JSON.NET to parse the string which works fine. I now try to use ajax to post it to my web service but have some issues with how to send the string. I have tried many ways but gets the common errors like
Invalid JSON primitive: myString.
So I checked this out [URL] and it works with hard coded values but I want to use a variable.
JavaScsript to create the object:
for (var i = 0; i < results.rows.length; i++) {
var row = results.rows.item(i);
var customer = new Object();
customer.id = row['id']
customer.name = row['name']
var customerString = JSON.stringify(customer);
$.ajax({
type: "POST",
url: "synchronise.asmx/synchroniseCustomers",
data: "synchroniseCustomers: " + customerString,
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (xhr, status) {
alert("An error occurred: " + status);
},
success: function (msg) {
alert("success");
}
});
}
WebMethod:
public void synchroniseCustomers(string customerString)
{
JObject o = JObject.Parse(customerString);
string id = (string)o["id"];
string name = (string)o["name"];
If I use data: '{ FirstName: "Dave", LastName: "Ward" }'
in the example above it works but I wish to pass on a string instead.
The ideal goal is to consume .asmx web service using jQuery like this
[Code]....
I need to pass a customer id to get some data back for a customer from a webservice. I can't figure out how to get to the webservice, I have a breakpoint set in the webmethod but it's not being hit and the alert box is not popping up either. For a test I am just trying to show some value from the returned data in an alert box. Note I am just hard coding the customer id of 1001. The webmethod takes a parameter of string customerid.
[Code]....
Does some one know what's missing or how to debug this issue?
