how to pass this via Json.Tried doing something like
var data = { Item1: "test", Item2: 5 };
var JSONdata = $.toJSON(data);
However that did not work. Although simply changing wcf to expect an object with two properties such as Item1 and Item2 will work. Here is example I'm using... I'll trim it a bit to make it easier to read:
function Post(data, url)
{
$.ajax({
type: 'POST',[code].....
I use the JavaScriptSerializer class of ASP.net to serialize my object and return it to the client side. How can I deserialize the string using JavaScript?
View 4 RepliesAs 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.
I've got code like this in a download page
Code:
Imports System.IO
Imports System.Data
Imports System.Data.SqlClient
Partial Class _Download
Inherits System.Web.UI.Page
[Code] .....
That is called like this:
Code:
function excelGrid(strId, blnDoReader) {
var wesPC = $("#" + strId);
var objWebParam = {};
var arrGrid = [];
[Code] ....
I am modifying this now - passing in the variable strWebParam which is the "stringified" version of a JSON array. And then in the function below I am trying to get the JSON-string into the POST. I tried the INPUT/TYPE=HIDDEN method you see below - but that did not work (cut off the string - it's got quotes in it)
Code:
$.downloadExcel = function(url, data, source, method, callback) {
var inputs = '';
var iframeX;
var downloadInterval;
if (url && data) {
[Code] ....
When I do a regular AJAX post for something I use the "data" element of the $.ajax method like this
Code:
var strWebParam = $.toJSON(objWebParam);
$.ajax({
type: "POST",
url: "WebService.asmx/BootPage",
dataType: "json",
[Code] .....
How is that DATA: STRWEBPARAM getting passed back to IIS??
I am creating one Json array object and trying to pass it in MVC controller action method but i am getting null paramerter; as per my knowledge json only maps .net primitive datatypes.... so it assign null value.

I try to use the jquery + json to get all elements in form and build a JSON var to post in a ASP.NET MVC method.
[Code]....
It method get all fields in a form and build a JSON, but it dont put JSON inside JSON.

<input name="person.name"><input name="person.age"><input name="person.address.street">
The serialized string build a JSON like this
{ "person.name": "??", "person.age": "??", "person.address.street": "??" }

I'm new to ASP.Net and need to pass a string value being recorded in a JavaScript function to a temporary string declared in VB.Net.
View 2 RepliesIn my javascript code I am getting json string from cs file
var tmpString="<%=resultset2%>";
In cs I am concatenating strings to build json string. Here is an issue the json string is returned as a string and it has " with it.
"[{id:'1',name:'Aik'},{id:'2',name:'Aik or Aik'}]"
Because of " in beginning and end javascript code treat it as a string.
public class Package
{
public Package()
{
name = "";
type = new List<Dictionary<string, string>>();
}
public string name { get; set; }
public List<Dictionary<string, string>> type { get; set; }

So how do construct the JSON from this?

I am developing a web application where in i have a WCF service which interacts with the database using entity framework. I want to get rid of creating Classes for each & every LINQ query
e.g
public class Emp
{
public int CD{get;set;}
public string Name{get;set;}
}
public List<Emp> GetServTypeForPromotionDue()
{
return (from a in Context.TableName
select new Emp{ a.CD, a.NAME });
}
for other table & LINQ i have to create a separate class every time. Alternative to this is to use Anonymous method which is not preferable solution. To avoid both the methods I am using Tuple Class where I return List> or List> depending on the return type. This works fine but the problem is I am binding the result of LINQ query directly to a Gridview By default Tuple has properties item1,item2,..& so on. So my griview shows these names are column names so, Is there any way I can change the property name to CD, Name instead of Tuple's Item1, Item2 before binding to grid?
I have a ASP.NET MVC 1.0 app.I have a listbox on the page and I want to pass an array to the webpage so that
javascript can use the array to do some processing depending on the item picked in the listbox.So I thought the best way is to pass JSON data to the webpage on load.So what is the best practice on how to do this?Can you please give me a brief step by step process.How do pass the array as JSON and how do I access it by index?
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 :(
This is regarding your article on

View 2 RepliesI m facing some problem. i m not passing Dynamic string through query string..
I m using this code
string abc = "CPCB_" + TextBox1.Text + "_" + TextBox2.Text;
Response.Write("<script>window.open('xml.aspx?Flag=3&date='+abc,target='new');</script>");
I have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?

What am I missing? msg.d.table[i]?
