数据注释不适用于所选的jquery插件

Question

我有一个包含多个htmlhelper控件的表单，如文本框和下拉列表。我已经使用数据注释对各个字段进行验证，并使用qtip来显示验证消息。我也使用了所选的jquery插件来增强UI。如果选择了插件调用，则数据注释不起作用。验证为itemlist工作，但不适用于其他两个..请帮助任何输入。这是我的代码：

我的观点 IndentItem.cshtml

if (ViewBag.isCreate == true)
 {
    <td>
        @Html.HiddenFor(model => model.Id)
        @Html.HiddenFor(model => model.IndentId)
        @Html.HiddenFor(model => model.ItemCode)
        @Html.HiddenFor(model => model.ItemType)

        @Html.DropDownListFor(model => model.DepartmentMachineId, Model.DepartmentMachineList, new { @class = "machineList input-medium" })
        @Html.ValidationMessageFor(model=>model.DepartmentMachineId)
    </td>
    <td>
        @Html.DropDownListFor(model => model.ItemName, Model.ItemNameList, new { @class = "itemList input-medium" })
    </td>
    <td>
        @Html.DropDownListFor(model => model.CategoryName, Model.CategoryNameList, new { @class = "catList input-medium" })
    </td>
    <td>
        @Html.DropDownListCustomFor(model => model.ItemId, Model.ItemCodeList, new { @class = "codeList input-medium" })
    </td>
    <td>
        @Html.TextBoxFor(model => model.ItemUnitDescription, new { placeholder = "unit type", @class = "input-small", @readonly = "true" })
    </td>
    <td>
        @Html.TextBoxFor(model => model.RequestedQuantity, new { placeholder = "quantity", @class = "input-small" })
    </td>

<div class="form-actions">
<button type="submit" class="btn btn-blue" >Save changes</button>`</div>
