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：
代码如下:<%@ 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>
    
    <div class="loginCon">
        <div class="loginBanner">
            <img src="/Images/4499633_182932517000_2.jpg" /></div>
        <div class="loginBox">
            <h2>
                <span class="fl">会员登录</span><span class="newUser">没有账号？<a href='<%=Url.Action("Register","Account") %>'>立即注册</a></span></h2>

            <form id="formData">
            <div class="loginForm">
                <div class="inputBox">
                    <input type="text" name="user" value="用户名/手机号" class="userId" />
                </div>
                <div class="inputBox">
                    <input type="text" value="密码" class="textStyle" />
                    <input type="password" name="pwd" class="passwordStyle none" />
                </div>
                <div class="warn">用户名或密码错误！</div>
                <div class="remember">
                    <label>
                        <input type="checkbox" name="remembered" checked />
                        自动登录</label>
                    <a class="forget" href='<%=Url.Action("ResetPwd","Login") %>' >忘记密码？</a>
                </div>
                <input class="loginBtn" type="button" value="登录"/>
            </div>
            </form>
        </div>
    </div>
</body>
<script type="text/javascript">
    $(function () {
        $('.userId,.passwordStyle').on('keyup', function (e) {
            if (e.keyCode == 13) {
                $('.loginBtn').trigger('click');
            }
        });

                return false;
            }
            var data = $("#formData").serialize();
            $.post("/login/checkLoginInfo", data, function (ajaxObj) {
                //回传内容{status: 1(success)/0(fail),}
                if (ajaxObj.status == 0 || status == null) {
                    $(".warn").show().html('用户名或密码错误！');
                } else {
                    //登陆成功，跳转都制定页面
                    window.location = '/memberCenter/index';
                }
