我正在使用在这里找到的 DateTimePicker：http: //trentrichardson.com/examples/timepicker/（请注意，如果我在 Jquery 中使用默认的 DatePicker，也会遇到下面描述的相同问题）。
我已经检查过我是否多次安装/重新安装了适当的 CSS、图像、jquery 版本，但我似乎找不到导致我的 DateTimePicker 看起来像这样的原因：
如果我删除所有 CSS（包括我网站的默认 MVC CSS），我会失去一周中的几天的蓝色背景（这些不应该由 Jquery UI 主题着色吗？）。
我需要去哪里解决我的问题？
编辑以显示我的代码：
这是我在页面中呈现的 PartialView：
<link href="@Url.Content("themes/ui-lightness/jquery-ui-1.8.19.custom.css")" rel="stylesheet"
type="text/css" />
<script src="@Url.Content("~/Scripts/jquery-1.7.2.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery-ui-1.8.19.custom.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery-ui-timepicker-addon.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/FillCourseForm.js")" type="text/javascript"></script>
<div id="CourseFormFields">
<p>the string is @ViewBag.selectedString</p>
@using (Html.BeginForm("ApplyToTeach", "Course", FormMethod.Post))
{
@Html.ValidationSummary(true)
<fieldset>
<div class="editor-label">
@Html.LabelFor(model => model.StartDate)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.StartDate)
@Html.ValidationMessageFor(model => model.StartDate)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
和jQuery：
$("#StartDate").datetimepicker({
ampm: true
});
生成的 HTML（被截断一点以防止大量代码墙）：
