asp.net-mvc – 不显着的验证不工作在动态添加的局部视图

我有一个视图强类型的模型(顺序)。此订单可以有很多项目。模型看起来像下面这样：

public class Order
{
    [Key]
    [HiddenInput]
    public int id { get; set; }

    [Display(Name = "Order Number")]
    public string number { get; set; }

    [Display(Name = "Order Date")]
    [DataType(DataType.Date)]
    [DisplayFormat(ApplyFormatInEditMode = true,DataFormatString = "{0:MM/dd/yyyy}")]
    public DateTime date { get; set; }

    [Required(ErrorMessage = "Beneficiary is required.")]
    [Display(Name = "Beneficiary")]
    public int beneficiary_id { get; set; }

    [Display(Name = "Beneficiary")]
    public Beneficiary beneficiary { get; set; }

    [Display(Name = "Items")]
    public List<Item> items { get; set; }

    [Display(Name = "Payment Method")]
    public List<PaymentMethod> payment_methods { get; set; }
}

我输入订单信息以及该特定订单的项目。我尝试了几种方式动态添加内容，最后去Steven Sanderson’s way。

在我看来，我有常规的订单信息，然后项目，我的模型看起来像这样：

@model trackmeMvc.Models.Model.Order
@{
    ViewBag.Title = "Create";
    Html.EnableClientValidation();
    Html.EnableUnobtrusiveJavaScript();
}

<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/MicrosoftAjax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftMvcValidation.js")" type="text/javascript"></script>

@using (Html.BeginForm("Create","Order",FormMethod.Post,new { @id = "create_order" }))
    {
    @Html.ValidationSummary(true,"Order creation was unsuccessful. Please correct the errors and try again.")

    <div class="editor-label">
        @Html.LabelFor(m => m.date)<req>*</req>
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(m => m.date,new { @id = "order_date" })<br />
        @Html.ValidationMessageFor(m => m.date)
    </div>

… …

<script type="text/javascript">

    $(document).ready(function () {

        $("#addItem").click(function () {

            var formData = $("#main_div").closest("form").serializeArray();

            $.ajax({
                url: "/IPO/BlankItemRow",type: "POST",//data: formData,cache: false,success: function (html) {
                    $("#editorRows").append(html);
                        //$.validator.uobtrusive.parseDynamicContent("form *");
                        //$("#editorRows").removeData("validator");
                        //$("#editorRows").removeData("unobtrusiveValidation");
                        //$.validator.unobtrusive.parse("#editorRows");
                        //$.validator.unobtrusive.parse("#create_ipo");
                        //$.validator.unobtrusive.parseDynamicContent($(this).first().closest("form"));
                        //$.validator.unobtrusive.parse($("#new_ipo_item"));

                        //$.validator.unobtrusive.parseElement($("#editorRows").find(".editRow:last").children().find("select"));
                           //$("#editorRows").find(".editRow:last").find("select").each(function () {
                           //alert($(this).attr("id"));
                           //$.validator.unobtrusive.parseElement($(this));
                           //$.validator.unobtrusive.parseDynamicContent($(this));
                           //$.validator.unobtrusive.parseDynamicContent($(this).attr("name"));
                       //});
                           //$("#editorRows").children().find(".editRows:last").find("*").each(function () {
                           //  alert($(this).attr('id'));

                           //$.validator.unobtrusive.parseDynamicContent('input');
                       //});
                       //var form = $(this).closest("form").attr("id");
                       //$(form).removeData("validator");
                       //$(form).removeData("unobtrusiveValidation");
                       //$.validator.unobtrusive.parse(form);
                    }
                });
            return false;
        });
    });

</script>

这些是我尝试的一些东西，没有什么工作。

我得到了parseDynamicContent从Applying unobtrusive jquery validation to dynamic content in ASP.Net MVC.我试过它在我可以想到的每一个场景，但仍然没有运气。

我也尝试了常规解析，从表单中删除验证，然后再次应用它，但仍然新添加的元素不验证：

<div id="editorRows">
    @foreach (var item in Model.items)
    {
        @Html.Partial("_NewItem",item)
    }
</div>

…和我的部分视图看起来像这样：

@model trackmeMvc.Models.Model.Item 

@{
    Layout = "";    
    Html.EnableClientValidation(true);

    if (this.ViewContext.FormContext == null)
    {
        this.ViewContext.FormContext = new FormContext();
    }
}

<div class="editRow">

@using (Html.BeginCollectionItem("order_items"))
{

    @Html.DropDownListFor(m => m.item_id,@items,"None",new { @style = "width:205px;",@id = "ddlItems",@class="ddlItem",@name="ddlItemList" })
    @Html.ValidationMessageFor(m => m.item_id)

    ...

}

</div>

所以发生了什么，我有一个空项目从控制器发送到视图默认情况下，显示一个空行。该项目已验证，但无论如何，当我单击添加项目，另一行出现，从该部分，但我不能得到它来验证。我试图把验证的局部视图，(在文档准备在主窗体)和我阅读的所有我应用，它总是结束相同：验证第一行，而不是其他。我试着验证史蒂文·桑德森为此目的 – 仍然没有运气 – 甚至验证的分数，发现at this link
和其后的页面是特定于部分验证…

我应该怎么做才能使验证工作？
