不显眼的验证不适用于动态添加的局部视图

Question

我目前在动态添加内容后面临验证问题.

我有一个强烈键入模型(Order)的视图.此订单可以包含许多项目.该模型看起来如下所示:

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.我尝试了几种方法来动态添加内容,最后采用Steven Sanderson的方式.

在我看来,我有常规订单信息,然后是项目,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>

这些是我尝试过的一些东西,没有任何作用.

我parseDynamicContent从ASP.Net MVC中的应用不显眼的jquery验证到动态内容.我在我能想到的每一个场景中都尝试过,但仍然没有运气.

我还尝试了常规解析,从表单中删除验证然后再次应用它,但仍然没有验证新添加的元素:

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

......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,默认情况下我从控制器向视图发送了一个空项,以显示一个空行.该项目已经过验证,但是当我点击添加项目时,无论出现什么,从该部分出现另一行,但我无法让它进行验证.我试图将验证放在局部视图中(在主窗体中准备好文档之前),以及我应用的所有内容,它总是相同:验证第一行,而不是其他行.我尝试了Steven Sanderson为此目的进行的验证 - 仍然没有运气 - 甚至是部分验证,在此链接 和随后的页面中找到了特定于部分验证的页面...

我该怎么做才能使这个验证工作？

Answer 1

好的,我将在这里重新开始一个新的答案.

在您致电之前,请$.validator.unobtrusive.parse从表单中删除原始验证器和不显眼的验证,如下所示:

var form = $("#main_div").closest("form");
form.removeData('validator');
form.removeData('unobtrusiveValidation');
$.validator.unobtrusive.parse(form);

这同样的答案被记录在这里.
