带有前缀的控件的 Asp.Net MVC2 客户端验证问题

发布于 2024-08-31 03:37:28 字数 1318 浏览 9 评论 0原文

问题是:当我在页面上放置 2 个相同类型的控件时,我需要指定不同的绑定前缀。在这种情况下,表单之后生成的验证规则不正确。那么如何获得该案例的客户端验证工作呢?:

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" });
%>

控件 ViewUserControl

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

其中 Model.GetPrefixed("CountryCode") 仅返回“FaxPhone.CountryCode”或“PhonePhone. CountryCode”取决于前缀


这里是表单后生成的验证规则。它们对于字段名称“Phone.CountryCode”是重复的。虽然所需的结果是每个 FieldNames“FaxPhone.CountryCode”、“PhonePhone.CountryCode”有 2 条规则(必填,数字) 替代文本 http://www.freeimagehosting.net/uploads/37fbe720bf.png

问题与 Asp.Net MVC2 客户端验证和重复 ID 有点重复问题 但手动生成 ids 的建议没有帮助。

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?:

the page contains:

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

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") })%>

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


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"

The question is somewhat duplicate of Asp.Net MVC2 Clientside Validation and duplicate ID's problem
but the advise to manually generate ids doesn't helps.

为文本框和验证设置相同前缀的正确方法:

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

where

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;
        }
    }
}

(偶然在 Steve Sanderson 博客 http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list- aspnet-mvc-2-style/

看起来 Html.EditorFor 方法也应该像这里建议的那样工作:ASP.NET MVC 2 - ViewModel 前缀

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) %>
<% } %>

where

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;
        }
    }
}

(by chance found the solution in the code on Steve Sanderson's blog http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list-aspnet-mvc-2-style/)

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