thanks, problem solved using below string:
data: "{name: '" + $('#Eid').val() + "', phone: '" + $('#phn').val() + "'}",

i have found out that problem is on my server side.

Thanks.

Hi, I want to send three text box values to server using jquery ajax. problem is that, i dont know the exact syntax to send three data. When i try sending one data(also change no.of parameters to one at server side method), its going good but when i try to send three text box values, its giving jquery error:"Internal server error". I think I am not sending data in correct way. please somebody tell me how to do that. Example below contains only two sending data, because i was trying to send 2 data first.

Below is the code:

function testCAll() { 
$.ajax({ 
    type: "POST", 
    url: "dbTest1.aspx/SendMessage", 
    data: "{'name': '" + $('#Eid').val() + "', 'phone': '" + $('#phn').val() + "'}", 
    //data: "{'phone': '" + $('#CustomerPhone').val() + "'}", 
    //data: "{'color': '" + $('#ColorId').val() + "'}", 
    contentType: "application/json; charset=utf-8", 
    dataType: "json", 
    success: function(result) { 
        resultData = eval("(" + result.d + ")"); 
        $("#rawResponse").html(concatObject(resultData)); 
    }, 
    error: function(result) { 
        alert("jQuery Error:" + result.statusText); 
    } 
});

thanks a lot! it works now. thank u so much

thanks but still problem is here. i can show my server code too if it helps u in determining my problem. but server side code is running good when i pass values like this:
data: "{'ntid':'stephen.gilroy1'}",

it only making problem when passing value of input textbox. server side method expects string value as an argument. may be there is the problem, that i have to convert it to string first in the server side method then do any processing. below is my C# code:

            {
                    foreach (DataColumn dc in dt.Columns) …

i have solved it by putting <br /> instead of "\n" in concatObject method like this: return strArray.join("<br />");

Hi, I am getting this error at runtime: object reference not set to an instance of object

my question is that am i using stringbuilder array correctly here. Because I am new in C#. and i think its the problem with my stringbuilder array. Below is the code:

            //DataTable dt = ws.GetEmployeeDetailsBy_NTID("650FA25C-9561-430B-B757-835D043EA5E5", "john"); 
 
            StringBuilder[] empDetails = new StringBuilder[100]; 
 
 
            string num = "ambreen"; 
            empDetails[0].Append("amby"); 
            num = empDetails[0].ToString();

            string output = jss.Serialize(htPeople); 
            return output; 
        } 
        catch(Exception ex) 
        { 
            return ex.Message + "-" + ex.StackTrace; 
        } 
    } 
}

please reply me what i am doing wrong here.

.aspx script is running fine. Problem is when i call server method from .ajax. That server method calls web service and convert returning data to json text and send back to java script. that web service is also working fine because i saw its result on page_load method. also i tried return just simple "Hello world" string(after converting it into json) but it gave the same result.

one thing i forgot to put in C# file was to write
[WebMethod()] above the sendMessage method.
but still showing the same result:(

Thanks airshow for quick reponse. I really appreciate it. when i try datatype: 'json' instead of 'JSON' it is giving parseerror. and when i see raw data using the code u given, it is showing the asp page result in the bottom of the page ( i mean displaying Testing.aspx again in the bottom). u have also seen my C# file in this thread. I also tried sending "hello world" string without convert it to json object but still got the same result. I think in ajax call, url "Testing.asp/sendMessage" is returning the whole script instead of sending just one string "Hello world". I am wondering that if it is calling just Testing.asp and not calling its method sendMessage.

Thanks Airshow,
I changed concatObect like yours. using json.decode didnt work but after making some changes to .ajax it is displaying this line given below:

toJSON value :function (key) { return this.valueOf(); }

and changes i have made are:

$.ajax({
            type: "POST",
            dataType: 'JSON',
            //data: "{'ntid':'stephen.gilroy1'}",
            //contentType: "application/json; charset=utf-8",
            //processData: false,
            url: "Testing.aspx/SendMessage",
            error: function(XMLHttpRequest, textStatus, errorThrown) {
                alert(textStatus);
            },
            success: function(result, txtStatus, httpRequest) {
                alert(txtStatus);
                the_object = result;
                $('#status').html(concatObject(the_object));
            }

can you please tell me why its not displaying the whole data and if i m using the correct way to display it? please reply me soon. Thanks

Hi,
In my code behind file, I called Soap web reference and retreive data and diplay in grid view and it worked. But when I convert retreived data to Json text and send back to java script and on client side, convert json text to java script object and when try to display it, its displaying nothing. I dont know if i m doing something wrong here. please check my code and give me suggestions, I really need help.

Below is the javascript file:

$.ajaxSetup({
    cache: false,
    timeout: 5000
});
var ajax_load = "<img src='loading.gif' alt='loading...' />";

//  load() functions
var loadUrl = "test.txt";

var the_object = {};

function concatObject(obj) {
    str = '';
    for (prop in obj) {
        str += prop + " value :" + obj[prop] + "\n";
    }
    return (str);
}


$(document).ready(function() {
    $("button").ajaxStart(function() {
        alert('Triggered ajaxStart handler.');
    });
    $("button").click(function() {
        $.ajax({
            type: "POST",
            dataType: 'JSON',
            url: "Testing.aspx/SendMessage",
            error: function(XMLHttpRequest, textStatus, errorThrown) {

                alert("success");
                the_object = httpRequest.responseText;
            }
