自定义 ValidationSummary 模板 Asp.net MVC 3 [英] Custom ValidationSummary template Asp.net MVC 3

问题描述

我正在使用 Asp.Net MVC3 开发一个项目

在视图中我有 @Html.ValidationSummary(true) 并且通常它会产生

<ul><li>发生了不好的事情！</li>

如何将此 ValidationSummary 扩展到 MyValidationSummary 并生成如下所示的 Html 代码模板:

<span></span><div class="text"><p>发生了不好的事情！</p>

解决方案

这个 问题 详细说明了编写自定义验证摘要的过程.

编辑这将执行您想要的操作:

公共静态类LinqExt{公共静态字符串 MyValidationSummary(这个 HtmlHelper 助手，字符串验证消息 ="){字符串 retVal = "";如果(helper.ViewData.ModelState.IsValid)返回 "";retVal += "
";如果 (!String.IsNullOrEmpty(validationMessage))retVal += helper.Encode(validationMessage);retVal += "</span>";retVal += "
";foreach (var key in helper.ViewData.ModelState.Keys){foreach(var err in helper.ViewData.ModelState[key].Errors)retVal += "
"+ helper.Encode(err.ErrorMessage) + "</p>";}retVal += "</div></div>";返回 retVal.ToString();}}

代码是不言自明的；只是在您选择的 dom 元素中枚举模型状态错误和包装错误.有一个错误，如果我像这样使用它:

<%:Html.MyValidationSummary()%>

它将在页面上将 html 标签显示为文本而不是呈现它.

<%=Html.MyValidationSummary()%>

这很好用.

I am working on a project with Asp.Net MVC3

In a View I have @Html.ValidationSummary(true) and as usually it produces

<div class="validation-summary-errors">
    <ul>
        <li>Something bad Happened!</li>
    </ul>
</div>

How can I extend this ValidationSummary to MyValidationSummary and produces the Html Code template something like this:

<div class="notification warning"> 
    <span></span> 
    <div class="text"> <p>Something bad Happened!</p> </div> 
</div>

解决方案

This question details the procedure of writing custom validation summary.

EDIT This will do what you want:

public static class LinqExt 
{
    public static string MyValidationSummary(this HtmlHelper helper, string validationMessage="")
    {
        string retVal = "";
        if (helper.ViewData.ModelState.IsValid)
            return "";

        retVal += "<div class='notification-warnings'><span>";
        if (!String.IsNullOrEmpty(validationMessage))
            retVal += helper.Encode(validationMessage);
        retVal += "</span>";
        retVal += "<div class='text'>";
        foreach (var key in helper.ViewData.ModelState.Keys) 
        {
            foreach(var err in helper.ViewData.ModelState[key].Errors)
                retVal += "<p>" + helper.Encode(err.ErrorMessage) + "</p>";
        }
        retVal += "</div></div>";
        return retVal.ToString();
    }
}

The code is self explanatory; just enumerating through modelstate errors and wrapping errors in dom element of your choice. There is an error that is if i use it like:

<%:Html.MyValidationSummary()%>

It will display html tags on the page as text rather than rendering it.

<%=Html.MyValidationSummary()%>

This works fine.
