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：

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>



<head runat="server">

    <title>ajax请求</title>

    <link type="text/css" rel="stylesheet" href="/Content/style.css" />

    <script type="text/javascript" src="/Scripts/jquery-1.8.3.min.js"></script>

    <script type="text/javascript" src="/Scripts/js.js"></script>

</head>

<body>

    

    <div class="logo_box">

        <div id="logo">

            <a title="ajax请求">ajax请求</a></div>

    </div>

            </form>

        </div>

    </div>

</body>

<script type="text/javascript">
