Fetch value using hidden field but not worked

Question

 My code as follows

 

 

function AddNewCriticalResource() {

var pro = $("#ms").val();

var ProjectIds = pro.toString();

var projectNames = $("#ms").text();

var addordelete = 1;

$.ajax({

type: "POST",

url: "CriticalResource.aspx/AddNewCriticalResource",

contentType: "application/json; charset=utf-8",

data: '{ stringAssociateIds: "' + associates + '", stringProjectIds: "' + ProjectIds + '", stringTaggedBy:"' + AssocID + '" }',

dataType: "json",

responseType: "json",

cache: false,

success: function (msg) {

var TableData = $.parseJSON(msg.d);

var alertString = '';

noOfRows = 0;

$.each(TableData, function (i, data) {

alertString = alertString + data.AssociateID + '-' + data.ProjectName + ', ';

noOfRows = i + 1;;

});

from the above code i want to get projectNames into code behind page.

i tried my code as follows

 

var projectNames = $("#ms").text();

 

$("#projectNames").val($("#ms").text());

 

<input type="hidden" id="projectNames" runat="server" clientidmode="Static"/>

 

My code behind page code as follows

 

string projectid = projectNames.Value; 

 

 var supplyData = this.objBusinessLayer.FetchCriticalResourceDetailsOnProjectId(projectid);

 

when i check the above code in code behind page, in the above line

 

 

string projectid = projectNames.Value;

in projectname value is not coming.

 

can you please tell me. what  is the mistake in my code. i tried but it is not working.
