首先解决 Ajax.BeginFor异步提交表单，给表单添加样式的问题。不能直接用class属性，网上找了很多都是用ClassName，经过测试不管用，看源代码发现生成的是ClassName而非class,其实很简单，加一个@符号即可，即@class="";
我们知道，LabelFor是不能添加class样式的，这个需自行拓展，反编译后自行拓展了一个给LabelFor添加样式的方法，代码如下：
1 using System;
2 using System.Collections.Generic;
3 using System.Linq;
4 using System.Web;
5 using System.Web.Mvc;
6 using System.Linq.Expressions;
7
8 namespace System.Web.Mvc
9 {
10 public static class MyLabelExtensions
11 {
12 public static MvcHtmlString MyLabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, string className)
13 {
14 return LabelHelper(html, ModelMetadata.FromLambdaExpression<TModel, TValue>(expression, html.ViewData), ExpressionHelper.GetExpressionText(expression), className);
15 }
16
17 private static MvcHtmlString LabelHelper(HtmlHelper html, ModelMetadata metadata, string htmlFieldName, string className = "")
18 {
19 string txtLabel = metadata.DisplayName ??
20 (metadata.PropertyName ?? htmlFieldName.Split(new char[] {‘,‘}).Last<string>());
21 if (string.IsNullOrEmpty(className))
22 {
23 return MvcHtmlString.Empty;
24 }
25 TagBuilder tagBuilder = new TagBuilder("label");
26 tagBuilder.Attributes.Add("for", TagBuilder.CreateSanitizedId(html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(htmlFieldName)));
27 tagBuilder.Attributes.Add("class", className);
28 tagBuilder.SetInnerText(txtLabel);
29 return new MvcHtmlString(tagBuilder.ToString(TagRenderMode.Normal));
30 }
31 }
32 }
先看效果：
