내 jQuery 코드 :

function sendmessage(){ 
var project_id = $("#DropDownList1 option:selected").val(); 
var formstatus = $("#DropDownList4 option:selected").val(); 
var formcode = $('#FormCText').val(); 
var uniquecode = getunique(); 
var to = $('.showto').attr("id"); 
var cc = getcc(); 

if ($('#urgent').prop("checked"==true)) 
{ 
var d = new Date(); 
var duedate = d.getFullYear() + "/" + (d.getMonth()+1) + "/" + d.getDate(); 
var urg = 1; 
} 
else 
{ 
var duedate=$('#datepicker').val(); 
var urg = 0; 
} 

if($('#readreceipt').prop("checked"==true)) 
{ 
var receipt = 1;

else{ 
var receipt = 0; 
} 
var fsub = $('#fsub').val(); 
var nicE = new nicEditors.findEditor('message'); 
var message = nicE.getContent();

$(document).timer = setTimeout(function() {

전송하는 데이터가 올바른 형식이 아니므로 시스템에서 발생하는 예외가 발생하므로 double 전송하기 전에 데이터를 확인하십시오. ... 그것은 롤 ','쉼표

$.ajax({ 
    type: "POST", 
    url: "consoservice.asmx/sendmessage", 
    data: JSON.stringify(Senddata), 
............ 
.............. 
});
