问题是:当我将2个同一类型的控件放在页面上时,我需要指定绑定的不同前缀。在这种情况下,表格后立即生成的验证规则不正确。那么如何使客户验证为该案件起作用?

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" });
%>

控制视图u003CPhoneViewModel>:

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

在哪里 Model.GetPrefixed("CountryCode") 只需返回“ faxphone.countrycode”或“ phone Phone.countrycode”,具体取决于前缀


这是表格之后生成的验证规则。它们以“ phone.countrycode”字段名称重复。虽然所需的结果是每个字段名称“ Faxphone.countrycode”,“ Phone Phone.CountryCode”的2个规则(必需的数字)虽然是2个规则(必需的编号)。Alt Text http://www.freeimagehosting.net/uploads/37fbe720bf.png

这个问题有些重复 ASP.NET MVC2客户端验证和重复ID的问题但是,手动生成ID的建议无济于事。

有帮助吗?

解决方案

正确的方法来为文本框和验证设置相同的前缀:

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

在哪里

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;
        }
    }
}

看起来HTML.Editor方法应尽其所能,并在此处建议: ASP.NET MVC 2 -ViewModel前缀
