I need to pass a value from the front end to the controller, I'm struggling to get it to pass the value. 

Ajax/Jquery

```
//unlock user account
    $("#results").on('click', ".unlockactionbutton", function (e) {
        e.preventDefault();
        var userid = this.getAttribute("userid");
        if (envdd.children(':selected').val() == "") {
            alert("Please select User"); 
        } else {
            alert(userid);
            $.ajax({
                type: "GET",
                url: "@Url.Action("UnlockUser", "Home", new { userid = userid })",
                //Url.Action("UnlockUser", "Home", new { id = userid });
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                data: JSON.stringify(userid),
                success: function (data) {
                    console.log(data);
                },
                error: function(data) {
                    alert('error');
                    console.log(data);
                }
            });
        }
    });

```

Here is the ActionResult. I've got the code simply putting a comment in the console so I can see that it's worked for now. 

```
[HttpPost]
    public ActionResult UnlockUser(string userid)
    {
        if (userid != "")
        {
            return Json("success - call from HomeController", JsonRequestBehavior.AllowGet);
        }
        else
        {
            return Json("error", JsonRequestBehavior.AllowGet);
        }
    }

```
