Asp.Net MVC2客户方的验证问题与prefixes控制 [英] Asp.Net MVC2 Clientside Validation problem with controls with prefixes

问题描述

的问题是：当我把相同类型的2控制在页面上我需要结合指定不同prefixes。在这种情况下，表格之后生成的验证规则是不正确的。因此，如何让客户端验证工作的情况：

The problem is: when I put 2 controls of the same type on a page I need to specify different prefixes for binding. In this case the validation rules generated right after the form are incorrect. So how to get client validation work for the case?:

该页面包含：

<%
    Html.RenderPartial(ViewLocations.Shared.PhoneEditPartial, new PhoneViewModel { Phone = person.PhonePhone, Prefix = "PhonePhone" });
    Html.RenderPartial(ViewLocations.Shared.PhoneEditPartial, new PhoneViewModel { Phone = person.FaxPhone, Prefix = "FaxPhone" });
%>

控制ViewUserControl＆LT; PhoneViewModel＆GT;

the control ViewUserControl<PhoneViewModel>:

<%= Html.TextBox(Model.GetPrefixed("CountryCode"), Model.Phone.CountryCode) %>
<%= Html.ValidationMessage("Phone.CountryCode", new { id = Model.GetPrefixed("CountryCode"), name = Model.GetPrefixed("CountryCode") })%>

其中， Model.Get prefixed（国家code）刚刚返回FaxPhone.Country code或PhonePhone.Country code根据preFIX

where Model.GetPrefixed("CountryCode") just returns "FaxPhone.CountryCode" or "PhonePhone.CountryCode" depending on prefix

和这里的形式后生成的验证规则。他们被复制的字段名Phone.Country code。虽然期望的结果是2规则（必填数）为每个FIELDNAMESFaxPhone.Country code，PhonePhone.Country code

And here is the validation rules generated after the form. They are duplicated for the field name "Phone.CountryCode". While the desired result is 2 rules (required, number) for each of the FieldNames "FaxPhone.CountryCode", "PhonePhone.CountryCode"

问题有所重复的<一个href=\"http://stackoverflow.com/questions/2675606/asp-net-mvc2-clientside-validation-and-duplicate-ids-problem\">http://stackoverflow.com/questions/2675606/asp-net-mvc2-clientside-validation-and-duplicate-ids-problem
但奉劝手动生成IDS不帮助。

The question is somewhat duplicate of http://stackoverflow.com/questions/2675606/asp-net-mvc2-clientside-validation-and-duplicate-ids-problem but the advise to manually generate ids doesn't helps.

推荐答案

要设置相同的prefixes正确方法既为文本框和验证：

Correct way to set the same prefixes both for textbox and validation:

<% using (Html.BeginHtmlFieldPrefixScope(Model.Prefix)) { %>
   <%= Html.TextBoxFor(m => m.Address.PostCode) %>
   <%= Html.ValidationMessageFor(m => m.Address.PostCode) %>
<% } %>

其中，

public static class HtmlPrefixScopeExtensions
{
    public static IDisposable BeginHtmlFieldPrefixScope(this HtmlHelper html, string htmlFieldPrefix)
    {
        return new HtmlFieldPrefixScope(html.ViewData.TemplateInfo, htmlFieldPrefix);
    }

    private class HtmlFieldPrefixScope : IDisposable
    {
        private readonly TemplateInfo templateInfo;
        private readonly string previousHtmlFieldPrefix;

        public HtmlFieldPrefixScope(TemplateInfo templateInfo, string htmlFieldPrefix)
        {
            this.templateInfo = templateInfo;

            previousHtmlFieldPrefix = templateInfo.HtmlFieldPrefix;
            templateInfo.HtmlFieldPrefix = htmlFieldPrefix;
        }

        public void Dispose()
        {
            templateInfo.HtmlFieldPrefix = previousHtmlFieldPrefix;
        }
    }
}

（偶然发现史蒂夫·桑德森的博客的http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list-aspnet-mvc-2-style/)

也像Html.EditorFor方法应该工作，以及在这里建议：的 ASP.NET MVC 2 - 视图模型preFIX

Also looks like Html.EditorFor approach should work as well as suggested here: ASP.NET MVC 2 - ViewModel Prefix
