C# - How To Send Json Data To Asmx (from Aspx) Using Jquery

Jun 21, 2010

i built contact form in aspx 3.5 and i'm using jquery to send it to web service (asmx).the web service need to return success or error code. the problem is that at the web method i get only single value and not array. I'm kind of new in ajax and i tried a lot of solutions but without any results.. please if you can only explain me the principle of what to do it also be good..this is the client side:

$(document).ready(function()
{
$("#submit").click(function(event)
{
[code].....

when i debug i see that the input parameter "name" contains only one string - i dont know how to get the full json string that i send to the service and contains all the form data - i want to desirialize it to string array or something like, and process it.

Jquery - JSON Can Call Method In .aspx File But Not In .asmx (web Service) File

Jul 3, 2010

I am using JQuery & JSON (POST) to call webmethod. However I can call only webmethod located at aspx file but not in asmx file Below are sample codes

CustomValidate.asmx
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Public Class CustomValidate
Inherits System.Web.Services.WebService
'ACCESS VIA JSON
<System.Web.Services.WebMethod()> _
Public Shared Function AJAX_Test(ByVal date1) As Boolean...
Return True
End Function
End Class
Javascript: JQuery JSON
function isDates(source, arguments) {
var isValidDate;
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CustomValidate.asmx/AJAX_Test",
data: '{date1: "' + arguments.Value + '"}',
dataType: "json",
async: false,
success: function(result) {
isValidDate = result;
},
error: function(httpRequest, textStatus, errorThrown) {
alert("status=" + textStatus + ",error=" + errorThrown);
}
});
arguments.IsValid = isValidDate;
}

It always return javascript undefined error. But if I put the AJAX_Test webmethod in aspx page and replace the url: "CustomValidate.asmx/AJAX_Test" to "mypage.aspx/AJAX_Test". It works fine.

WCF / ASMX :: Send A JSON Data Packet Back To Requester?

Mar 7, 2011

We have an exisiting Web Service which receives SOAP requests and returns the data accordingly. However, we have a new project which requires the same information but the Android SDK doesn't support SOAP so we need to use JSON. As JSON is just a data container format, I need to write a new module to replace the SOAP WSDL which receives a querystring from the Android app and then processes the data and returns it in a JSON packet. The problem is that having never used JSON I'm unsure as to how I return the data to the app in JSON format. Does anyone have any examples I can look at in VB.Net or C#?

JQuery - ASPX Security Libraries / Looking For A Combo To Send Data From JavaScrpit To ASPX?

Jun 6, 2010

i would like to know if there's a combo like jCryption (jCryption) - PHP but for jQuery - ASPX.I mean, I have been searching for a combo to send data both ways (Client-server, server-client) with jQuery to ASPX. The best I found was jCryption that sends data from JavaScrpit to PHP. I need a combo to send data from JavaScrpit to ASPX.

PD: Please don't tell me to use HTTPS, it's not enough to ensure the data communication on a client - server application.

WCF / ASMX :: Write Endpoint To Communicate With JSON From Jquery On Page?

Aug 31, 2010

i need to be able to expose information to a page, and I need to write the information in xml on my webserver which will be dynamically created from the database.

I need to use json to pass the data from the screen back to the server two way communication xms back and forth. Is it actually any good using a wcf endpoint to serve the json back to the page and use query with wcf? Is this possible?

Or is it easier to use standard pages .aspx and just do a call to a url and get the json with jquery....

We will probably want to send this information to other locations at some point in the future too....

WCF / ASMX :: Send Output Of Web Service From Xml As An Attachment To An Aspx Page?

Apr 8, 2010

i have designed a web service which would create 2 csv files on the system. I want to send the links to the location of the files as an url attachment over the aspx page.

like : http://myserver/download.aspx?file1=C: empimage1.png&file2=C: empimage2.png

the output from the asmx web service is : [Code]....

where xx.xx.xxx.xxx is the ipaddress. this is the whole output i get from the webservice.

how do i get the aspx page to send the attachment in the format i mentioned above? I have added an asp website to the project and added the webservice as a web reference to this but i do not know how to get the location from the xml output file of the webservice result.

Return Data From An Asmx Into JSON?

Jun 15, 2010

I want to return an array of javascript objects from my asp.net asmx file. ie.

variable = [
{
*value1*: 'value1',[code]....

I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable.

EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.

WCF / ASMX :: Return JSON Data From A 2.0 Web Service?

Sep 10, 2010

Just ramping up on JSON and JQuery and returning data to a ASP.NET web page from a web service using Ajax. The JQuery part is pretty straight-forward. However, when trying to return JSON formatted data instead of XML from a 2.0 web service, I'm stuck. The web service does have the System.Web.Script.Services.ScriptService attribute, so I can hit it via JavaScript; however, the web service always...always...returns data in XML format, no matter if I explicitly say I want JSON as the datatype in my JQuery code. So I don't know if this is an issue with the web service or the JQuery code. I posted this here, but realize that the category could be incorrect depending on where the issue is. Is there no way to return JSON data from a 2.0 web service? It's a production web service, so I can't change the code unfortunately.

Send JSON Data To HTTP Handler?

Nov 14, 2010

i have an ASP.NET 4.0 HTTP handler that should receive and send data in json format. I'm using jquery to send json objects serialized in a string to the handler. It correctly sends the request but i don't know how i could retrieve the data from the httpcontext passed to the handler and how i could deserialize it..

UPDATE 1

$.ajax({
type: "POST",
url: "myurl.ashx",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: $.toJSON({
...
}),
success: function (response) {

WCF / ASMX :: Windows Communication Foundation Service Returning Xml / Json Data?

Aug 25, 2010

I Need by service contract to return the xml/json result depending on the request type. function which will convert my result set (i am using linq to sql) so that i do not need to create the xml format for the result set by iterating through the table row many times.What is the suitable way to do that.

I need a kind of short cut method which will convert the table data to xml result.Had i been using asp.net mvc i would have been able to generate the xml data by overriding the the ExecuteResult method in the ActionResult and giving Conetnt-Type = "text/xml" as OP.But since i am using Wcf i don't have the controller context(as controller context is the parameter that needs to be passed to Execute Result).

My present code for converting the table data to the xml format is below.

public XDocument UsersLists(string authToken)
{
bool IsAuthenticated = Authenticate(authToken);
XDocument xDoc = new XDocument();
XElement root = new XElement("Users");

[Code]....

I need to eliminate this way of generating xml for each table records.

JQuery :: Get JSON Call To MVC Controller Not Returning Data

Nov 25, 2010

This is probably something simple. The following JQuery call is executing and calling the controller. The controller is executing correctly. I used the sample data that's commented out to verify that the templates were working also. However, the success function is not executing in the browser. Any thoughts or other ways I can debug this?

<script type="text/javascript">$(document).ready( function(){ alert("Here"); @* var myData = [ {first: "Jane", last: "Doe"}, {first: "John", last: "Doe"} ]; *@ $.getJSON( "/User/Filter",function(myData){ $("#myDataTemplate").tmpl(myData).appendTo("#itemContainer"); } ); alert("there"); }
);</script>
//Controller
public ActionResult Filter() { var myData = this.repository.GetAllUsers(); //return Json(myData); return Json(myData, JsonRequestBehavior.AllowGet);}
