I am working with Servlet and JSP. I have a JSP form in which I have a drop down list with `id's` associated with it, as of now I have three options in the drop down list.

HTML CODE--

<form id='form' method='post' action='/test/'>

    <select id="type" name="typeOne">

<optgroup id="first" name="First" label="FirstDiv">

    <option value="value1" id="001">valuee1 count</option>

<option value="value2" id="002">value2</option>

<option value="value3" id="003">value3

</option>

</optgroup>

</select>

</form>

Now I need to disable few of the options in my above drop down list using jquery. Below is my jquery in which I am disabling the `option` with the list of `id's` that I get from my servlet. 

`Store` is the value that I am passing from my servlet and is a `List`-

JQuery code--

     <script>

       $(document).ready(function () {

            $(function () {

                  alert(<%=request.getAttribute("store") %>);

                  $(<%=request.getAttribute("store") %>).prop("disabled", true);

        

                });

            });

     </script>

In 'Alert' I am getting the value as null

Below is my servlet from which I am passing a list which will have all my id's which I want to disable in my drop down list.

Servlet code--

    List<String> storeTest = new ArrayList<String>();

    storeTest.add("001");

    storeTest.add("002");

    req.setAttribute("store",StringUtils.join(mapForId(storeTest).toArray(),",")); 

    this.getServletContext().getRequestDispatcher( "/myPage.jsp" ).forward( req, response );

    

Problem Statement:-

Now my question is - In my JSP page the options in the drop down, it does not get disabled after its been passed. Can anyone please correct me what am I doing wrong.
