如何在ASP.NET MVC中扩展ValidationSummary HTML Helper？

我需要将验证摘要包装在div中.当出现错误时,如何设置验证摘要以将其包装为div？

<div class="validation-summary"> 
  <%= Html.ValidationSummary("Login was unsuccessful. Please correct the errors and try again.") %>
</div>

解决方法

虽然这是不同的,你可以创建自己的扩展方法…

namespace System.Web.Mvc
{
    public static class ViewExtensions
    {
        public static string MyValidationSummary(this HtmlHelper html,string validationMessage)
        {
            if (!html.ViewData.ModelState.IsValid)
            {
                return "<div class="validation-summary">" + html.ValidationSummary(validationMessage) + "</div>"
            }

            return "";
        }
    }
}

然后打电话

<%= Html.MyValidationSummary(
    "Login was unsuccessful. Please correct the errors and try again.") %>
