本文实例讲述了.NET的Ajax请求数据提交实现方法。分享给大家供大家参考。具体如下：

  1. <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>   
  2.    
  3. <head runat="server">   
  4.     <title>ajax请求</title>   
  5.     <link type="text/css" rel="stylesheet" href="/Content/style.css" />   
  6.     <script type="text/javascript" src="/Scripts/jquery-1.8.3.min.js"></script>   
  7.     <script type="text/javascript" src="/Scripts/js.js"></script>   
  8. </head>   
  9. <body>   
  10.     <!--顶部+logo+导航-->   
  11.     <div class="logo_box">   
  12.         <div id="logo">   
  13.             <a title="ajax请求">ajax请求</a></div>   
  14.     </div>   
  15.     <!---->
