不引人注目的验证不工作的动态添加局部视图 [英] Unobtrusive validation not working on dynamically-added partial view
问题描述
我目前面临着验证出现问题后动态添加内容。
I am currently facing a problem with validation after dynamically adding content.
我有一个观点强类型到模型（订单）。这条命令可以有很多的项目。该模型看起来像下面这样：
I have a view strongly typed to a model (Order). This Order can have many items. The model looks something like the following:
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，并针对特定顺序的项目。我尝试了几种方法来动态地添加内容，最后用的史蒂芬·桑德森的方式。
在我看来，我有正常秩序的信息，然后将物品，在我的模型看起来是这样的：
In my view, I have the regular Order information and then the items, where my model looks something like this:
@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>
这些都是一些我试过的东西，没有什么作品。
Those are some of the things I tried, and nothing works.
我得到了 parseDynamicContent 来自的申请不显眼的jQuery验证在ASP.Net MVC 的动态内容。我试图在每一个场景中我能想到的，但仍没有运气。
I got the parseDynamicContent from Applying unobtrusive jquery validation to dynamic content in ASP.Net MVC. I tried it in every scenario I could think of, but still no luck.
我也试过常规解析，从表单删除验证然后再应用它，但还是新加入的元素不进行验证：
I also tried the regular parse, removing validation from the form then applying it again, but still the newly added elements are not validated:
<div id="editorRows">
@foreach (var item in Model.items)
{
@Html.Partial("_NewItem", item)
}
</div>
...和我的部分观点将是这个样子：
... and my partial view would look something like this:
@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>
那么是什么发生的事情是，我从控制器到默认视图发送的一个空项目，显示一个空行。该项目被确认，但是当我点击添加项目，会出现另一行后，无论发生什么事，从局部的，但我不能得到它来验证。我试图把验证的局部视图，（文档准备在主窗体之前），和一切我读我申请，而且最终总是一样：验证第一行，而不是其他。我试图史蒂芬·桑德森为这一目的进行的验证 - 仍然没有运气 - 即使验证的谐音，发现的这个链接
和其后该页面是特定部分验证...
So what's happening is, I have one empty item sent from the controller to the view by default, to show one empty row. That item is validated, but whatever comes after when I click add item, another row appears, from that partial, but I can't get it to validate. I tried to put the validation in the partial view, (before the document ready in the main form), and everything I read I applied, and it always ends up the same: validating the first row, and not the others. I tried the validation of Steven Sanderson done for that purpose - still no luck - even the validation for partials, found at this link and the page that follows which is specific to partial validation...
我应该怎么做才能得到这个工作的验证？
What should I do to get this validation working?
推荐答案
好吧，我要拍一部新的答案开始。
Ok, I am going to start over with a new answer here.
在调用 $ validator.unobtrusive.parse ，从像这样的形式删除原来的验证和不引人注目的验证：
Before you call $.validator.unobtrusive.parse, remove the original validator and unobtrusive validation from the form like so:
var form = $("#main_div").closest("form");
form.removeData('validator');
form.removeData('unobtrusiveValidation');
$.validator.unobtrusive.parse(form);
这同样的答案就在这里记录。
This same answer is documented here.
