Set Session variable in ASP.Net MVC using jQuery

In this tutorial, I will show you how to set a session variable in an ASP/NET MVC using jQuery.

jQuery is a Javascript library, which is a client-side language. Setting a session variable using a client-side function is not possible. So we make an Ajax Call using a jQuery to pass the variable value to the controller and set a session variable.

Now let get started by creating a model Country as shown below.

The Model

    public class EmployeeModel
    public class CountryModel
        public string countryName { get; set; }

The Controller:

        public ActionResult Index()
            return View();

        public JsonResult SetSession(string name)
            Session["CountryName"] = name;
            CountryModel countryModel = new CountryModel()
                countryName = Session["CountryName"].ToString()


            return Json(countryModel);

As you see, the controller contains two methods:

The index() method that takes you to the index page

The SetSession() method that gets triggered when a user clicks on the button.

The View

    Select a Country:
<select id="ddl">
    <option value="Australia">Australia</option>
    <option value="France">France</option>
    <option value="United Kingdom">United Kingdom</option>
    <option value="United States">United States</option>

<input type="button" id="btnSet" value="Set Session" />
<script src=""></script>

<script type="text/javascript">
    $(function () {
        $("#btnSet").click(function () {
                type: "POST",
                url: "/Home/SetSession",
                data: '{name: "' + $("#ddl").val() + '" }',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (response) {
                    alert("You selected: " + response.countryName);

Now run the solution; you should get the result below
