JQuery 不会将任何内容传递给 ASP.NET Controller

Question

我已经使用了大约两天，搜索和尝试。但我仍然无法实现我的目标:

将 Jquery 对话框 slider 值传递给 Controller ​​。

前端:

@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>

Javascript文件:

$(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());
    }

有人可以帮助我，让它发挥作用，并向我解释我做错了什么吗？

看来您在 JavaScript 文件中包含了 Razor 代码:@Url.Action("User", "CheckInMood")。

由于这是一个 javascript 文件，因此 Razor 将不会用于呈现该值，因此会将其视为文字。

您需要做的是将 URL 从 View 传递到 JavaScript。
