How to get text from hidden field in HTML by using jQuery

I need to get the value out of the hidden field using jQuery.
My code, where I hide some value is following:

(...)$.each(response, function (index, value) {
$('<li>Nowa wiadomosc : ' + value.Subject +
' od ' + value.Receive + ' data ' + ToJavaScriptDate(value.Date)
+ ' </li>' + '<li style = "display: none;">' + value.IDMessage + '</li>'))

and after the value.IDMessage is hidden, I have to get its value again, and pass to another place. The code is following:

(...)$("#notiContent").delegate('li', 'click', function () {
var type = $(this).val(); (...)

Unfortunately the
variable gives 0 all the time. When I changed
it works, but I am not able to get the value out of hidden field.

How can I do this?

try this out , I think this is what you want.in this example I have shown you how to get the hidden field values from static elements and , how to get hidden field values in dynamic environment.

note : when you want to assign and get values from hidden field, best practice is to use field with type="hidden".

try below two examples and try.good luck.


<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>


<h2>Get the value from static element ---> Note : to get the hidden value, best practice is to use <span style="background-color:red;color:white;">input</span> field</h2>

<div id="notiContentone">
  <li style="cursor:pointer;">Nowa Wiadomosc bla bla bla</li>
  <input type="hidden" id="myhidden" value="give_your_value_here">


<h2>Get the value from dynamic elements</h2>
<div id="notiContentwo"></div>


<script type="text/javascript">

//get the value from static element implement 
$("div#notiContentone li").click(function(){// in here we choose the li element inside the notiContentone
      var hiddenValue = $("#myhidden").val(); //here we get the assinged value for the hidden field.

//get the value from dynamic elements
  var createelement_li = $('<li style="cursor:pointer;color:orange;background-color:pink;width:400px;">Nowa Wiadomsc bla bla bla </li>');
  var createelement_hidden_input = $('<input type="hidden" id="myhiddentwo" value="dynamically_added_value_here">');
  $("div#notiContentwo li").click(function(){
    var gettheHiddenValue = $("#myhiddentwo").val();
