Question

Hi All
  I try create list item using REST in SharePoint 2013.  when code is try add new item in list , getting error :
A node of type 'EndOfInput' was read from the JSON reader when trying to read the start of an entry. A 'StartObject' node was expected.
Please help me

var title = $('#txtTitile').val();
//alert(title);
var items = {
__metadata: { "Type": "SP.Data.OrderDetailsListItem"},
Title:title
var exec = new SP.RequestExecutor(appweburl);
exec.executeAsync(
url: appweburl + "/_api/SP.AppContextSite(@target)/web/lists/getbytitle('OrderDetails')/Items?@target='" + hostweburl + "'",
method: "POST",
data: JSON.stringify(items),
headers: {
Accept: "application/json;odata=verbose",
"Content-Type": "application/json;odata=verbose",
"X-RequestDigest": $("#__REQUESTDIGEST").val()
success: function (data) { alert(JSON.parse(data)); },

Hi,                                                             
Here is a demo which works in my environment for your reference:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
$("#Button1").click(function(){
createListItemWithDetails("list2", "http://sp2013sps", "item1");
// Getting the item type for the list
function GetItemTypeForListName(name) {
//alert("GetItemTypeForListName: "+name);
return"SP.Data." + name.charAt(0).toUpperCase() + name.slice(1) + "ListItem";
// CREATE Operation
// listName: The name of the list you want to get items from
// siteurl: The url of the site that the list is in. // title: The value of the title field for the new item
// success: The function to execute if the call is sucesfull
// failure: The function to execute if the call fails
function createListItemWithDetails(listName, siteUrl, title) {
var itemType = GetItemTypeForListName(listName);
//alert("itemType :"+itemType);
var item = {
"__metadata": { "type": itemType },
"Title": title
$.ajax({
url: siteUrl + "/_api/web/lists/getbytitle('" + listName + "')/items",
type: "POST",
contentType: "application/json;odata=verbose",
data: JSON.stringify(item),
headers: {
"Accept": "application/json;odata=verbose",
"X-RequestDigest": $("#__REQUESTDIGEST").val()
success: function (data) {
location.href=location.href;
//success(data);
error: function (data) {
alert("error");
//failure(data);
</script>
<input id="Button1" type="button" value="Run Code"/>
