JQuery won't pass anything to ASP.NET Controller

I've been using like two days now, searching and trying. But still i'm not able to achieve my goal:

Pass an Jquery dialog slider value to the controller.

Frontend:

@model TheMoodApp.Models.tbl_user
@{
    ViewBag.Title = "ControlPanel";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>@Html.DisplayFor(u=>u.Forename)'s Control Panel</h2>
@* Adding header stuff for control panel *@
@section DialogControlPanel{
    <link rel="stylesheet" href="http://code.jquery.com/ui/1.9.2/themes/base/jquery-ui.css" />
    <script src="http://code.jquery.com/jquery-1.8.3.js"/>
    <script src="https://raw.github.com/brandonaaron/bgiframe/master/jquery.bgiframe.js"/>
    <script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"/>
    <script src="~/Scripts/MoodAppScripts.js"/>
    <link href="~/Content/MoodApp.css" rel="stylesheet" />
}
@*The dialog for set initial mood*@
<div id="dialog-modal" title="Hi @Html.DisplayFor(u=>u.Forename)<br/>How do U feel 2Day?">
    <header id="InitialMoodHeader">
        <p>Set UR Mood 
            <input type="text" id="DisplayMood" readonly="readonly"/>
        </p>
    </header>
    <section id="InitialMoodSlider">
        <div id="MoodSlider"></div>
    </section>
</div>

Javascriptfile:

$(document).ready(

function () {
    $("#dialog-modal").dialog({
        height: 140,
        modal: true,
        buttons: {
            "This is my Mood": function () {
                $.ajax({
                    url: '@Url.Action("User", "CheckInMood")',
                    data: JSON.stringify({ mood: $("#DisplayMood").val() }),
                    type: 'POST',
                    contentType: 'application/json; charset=utf-8',
                });
                $(this).dialog("close");
            }
        }

    });

    $("#MoodSlider").slider({
        //TODO: IMPLEMENT JSON TO GET MOOD; ATM FEATURE IS FIXED.
        range: "max",
        min: 0,//scales minimum
        max: 3,//scales maximum
        value: 2,//default value
        slide: function (event, ui) {
            $("#DisplayMood").val(ui.value);//get value from slider and display it
        } 
    });
    $("#DisplayMood").val(
        $("#MoodSlider").slider("value")
        );//set input value from slider
});

Controller:

[HttpPost]
    public JsonResult CheckInMood(string mood)
    {
        //current user checks in with current mood
        uint i = Convert.ToUInt16(mood);
        return Json(View());
    }

Could someone plz help me, getting this to work, and explain to me what i've done wrong?

Thanks in advance

@Url.Action is only usable from within the razor file itself then, being it in the script tag and so, and now where else? (Just to clarify)

It appears you are including Razor code: @Url.Action("User", "CheckInMood") in your JavaScript file.

Since this is a javascript file, Razor will not be used to render that value so it will treat it as a literal.

What you'll want to do is pass in the URL from your View into JavaScript.

change:

data: JSON.stringify({ mood: $("#DisplayMood").val() })

to:

data: { mood: JSON.stringify($("#DisplayMood").val()) }

You need to stringify the parameter's value, not the parameter name.
