Is there a similar functionality in jQuery as Session["Param"] in C#? How can I use it?

I've searched "sessionStorage" in jQuery, but I can't understand.

As you said, you can use sessionStorage in JavaScript.

▶ You can set a new parameter like so:

sessionStorage.param1 = "Hello";
/* Or */
sessionStorage.setItem("param1", "Hello");

▶ Then, you can get it as follows:

var param = sessionStorage.param1;
/* Or */
var param = sessionStorage.getItem("param1");

console.log(param); /* It'll output `Hello`. */

---

Notes:

▶ Using sessionStorage, you can only store data for one session, which means everything will be deleted if you close the specific browser tab. If you want to permanently store data use localStorage instead.

▶ As you are apparently very new to JavaScript, I suggest you take a look at the following documentation about Web Storage in JavaScript:

• Mozilla Development Network (sessionStorage, localStorage)
• W3 Schools (both)

// ${FEEDBACK_QUESTION_IDS} this is session attribute name in controller

<script type="text/javascript">
    $(document).ready(function() {  
        window.questionIdsList = [];
        var i = 0;
        <c:forEach items="${FEEDBACK_QUESTION_IDS}" var="queId">
        questionIdsList[i] = parseInt(${queId});
        i++;
        </c:forEach>

    });
</script>

Finally we can use window.questionIdsList as same as array

The following can be used to store and retrieve data in the following ways:

To store:

sessionStorage.setItem("error", 'some value');

To retrieve:

sessionStorage.getItem("error");

To use session data ,you don't need jquery you can use setItem ,getItem and removeItem to deal with the session data which is stored as a json object and accessible via key.
