如何禁用选定的日期（asp.net mvc4）

Question

我正在尝试在 MVC4 中进行预约页面。它运行良好，但我想禁用选择的日期。这是我的负责人进行预约：

public ActionResult Make()
       {
           return View();
       }
       [HttpPost]
       [ValidateAntiForgeryToken]
       public ActionResult Make(Models.AppModel User)
       {
           if (Session["UserEmail"] != null)
           {
               using (var db = new MaindbModelDataContext())
               {
                   var patient = db.Patients.FirstOrDefault(u => u.Email == (String)Session["UserEmail"]);

                   var app = new Appointment();

                   app.Date = (DateTime)User.Date;
                   app.Description = User.Description;
                   app.Status = "isPending";
                   app.PatientNo = patient.PatientNo;
                   app.AppNo = Guid.NewGuid().GetHashCode();
                   db.Appointments.InsertOnSubmit(app);
                   db.SubmitChanges();

               }
           }
           else
           {
               return RedirectToAction("Index", "User");
           }
           return RedirectToAction("Index", "Patient");
       }
       //
   }
}

这是我对日期选择器的看法

@model DentAppSys.Models.AppModel
@{
    ViewBag.Title = "Appointment";
}
<link type="text/css" rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken();
    @Html.ValidationSummary(true, "");
    <div>

        <fieldset>
            <legend>Get an Appointment</legend>


            <div>@Html.LabelFor(u => u.Date)</div>
            <div>
                @Html.TextBoxFor(u => u.Date, htmlAttributes: new { id = "DatePicker" })
                @Html.ValidationMessageFor(u => u.Date)

            </div>

            <div>@Html.LabelFor(u => u.Description)</div>
            <div>
                @Html.TextBoxFor(u => u.Description)

            </div>

            <input type="submit" value="Submit" class="footer_btn" />

        </fieldset>

    </div>
}
<script type="text/javascript">
    $(function () {
        $("#DatePicker").datepicker();
    });

</script>

在我看来，“日期”的 TextBoxFor 可能会被禁用，具体取决于条件。 你可以试试这个。

@using (Html.BeginForm())
        {
            @Html.AntiForgeryToken();
            @Html.ValidationSummary(true, "");
            <div>

                <fieldset>
                    <legend>Get an Appointment</legend>


                    <div>@Html.LabelFor(u => u.Date)</div>
                        <div>
        @{
string idAttr="";
        if(condition_for_disable==true)
        {
idAttr="DatePicker";
}
                            @Html.TextBoxFor(u => u.Date, htmlAttributes: new { id = idAttr })

          }                  @Html.ValidationMessageFor(u => u.Date)

                        </div>

                    <div>@Html.LabelFor(u => u.Description)</div>
                    <div>
                        @Html.TextBoxFor(u => u.Description)

                    </div>

                    <input type="submit" value="Submit" class="footer_btn" />

                </fieldset>

            </div>
        }


<script type="text/javascript">
    $(function () {
        $("#DatePicker").datepicker();
    });

</script>

Answer 2

@Html.TextBoxFor(u => u.Date, htmlAttributes: new { id = "DatePicker", disabled="disabled" })

或

@Html.TextBoxFor(u => u.Date, htmlAttributes: new { id = "DatePicker", @readonly="true" })

Answer 3

请在 JavaScript 代码上试一试.. 希望对您有所帮助..

<script type="text/javascript">
    $(function () {
        $("#DatePicker").datepicker();

        $("#DatePicker").attr('disabled','disabled')

    });

</script>

以上是禁用所有日期选择器，其 id 为：#DatePicker 因此，在您发表评论后更新代码：

$('#DatePicker').datepicker({
   beforeShowDay: function (dt) {
       var bDisable = arrayDisabledDates[dt];
       if (bDisable) 
          return [false, '', ''];
       else 
          return [true, '', ''];
   }
});

arrayDisabledDates 是日期数组

var arrayDisabledDates=[...,...,..]
