Why is the data not being passed to the controller?

Question

ASP.NET

I have this script:

<script type="text/javascript">
        $(function () {
            $("input:checkbox").click(function () {
                $.ajax({
                    type: 'POST',
                    url: '/Project/Index/',
                    dataType: "html",
                    data: "Hello",
                });
            });
        })
    </script>

And there is this controller:

[HttpPost]
        public ActionResult Index(string stat)
        {
            return View();
        }

I checked in the debugger, we get into this controller, but stat is null. In what there can be a business and how to solve?

Answer 1

I haven't dealt with ASP.NET for a hundred years, but I suppose that if you write in the front-end:
then everything will work.

Answer 2

Try this
. Well, of course, the object should be sentdata: { stat: "Hello" }
