asp.net-mvc - jQuery 日期时间选择器 MVC3

Question

我的模型中有这个字段

[DataType(DataType.DateTime)]
    [Required(ErrorMessage = "Expire is required")]
    public DateTime Expire
    {
      get;
      set;
    }

在我看来

@Html.EditorFor(model => model.Expire))
      @Html.ValidationMessageFor(model => model.Expire)

然后我创建 DataTime EditorTemplates

@inherits System.Web.Mvc.WebViewPage<System.DateTime>
@Html.TextBox("", (Model.ToShortDateString()), new { @class = "datePicker" })
<script type='text/javascript'>
  $(document).ready(function () {
    $(".datePicker").datepicker({
      //      buttonImage: "/content/images/calendar.gif",
      //      showOn: "both",
      //      defaultDate: $("#calendar-inline").attr('rel')
      showAnim: 'slideDown',
      dateFormat: 'dd/mm/yyyy'

    });
  });
</script>

当我尝试创建新项目时，我收到此错误消息

The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'

我试试

Model.HasValue ? Model.Value.ToString("MM/dd/yyyy") : DateTime.Today.ToShortDateString()

但我没有模型值检查

尝试以下方法之一:

• 如果操作是为了创建新对象，则传递一个新实例作为模型，例如return View(new MyObject())
• 更改@inherits System.Web.Mvc.WebViewPage<System.DateTime>至@inherits System.Web.Mvc.WebViewPage<System.DateTime?>
