如何在.NET中使用Ajax請求提交數據?相信很多沒有經驗的人對此束手無策,為此本文總結了問題出現的原因和解決方法,通過這篇文章希望你能解決這個問題。

具體如下:

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

 
<head runat="server"> 
    <title>ajax請求</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> 
    <!--頂部+logo+導航--> 
    <div class="logo_box"> 
        <div id="logo"> 
            <a title="ajax請求">ajax請求</a></div> 
    </div> 
    <!----> 
    <div class="loginCon"> 
        <div class="loginBanner"> 
            <img src="/Images/4499633_182932517000_2.jpg" /></div> 
        <div class="loginBox"> 
            <h3> 
                <span class="fl">會員登錄</span><span class="newUser">沒有賬號?<a href='<%=Url.Action("Register","Account") %>'>立即注冊</a></span></h3> 
 
            <form id="formData"> 
            <div class="loginForm"> 
                <div class="inputBox"> 
                    <input type="text" name="user" value="用戶名/手機號" class="userId" /> 
                </div> 
                <div class="inputBox"> 
                    <input type="text" value="密碼" class="textStyle" /> 
                    <input type="password" name="pwd" class="passwordStyle none" /> 
                </div> 
                <div class="warn">用戶名或密碼錯誤!</div> 
                <div class="remember"> 
                    <label> 
                        <input type="checkbox" name="remembered" checked /> 
                        自動登錄</label> 
                    <a class="forget" href='<%=Url.Action("ResetPwd","Login") %>' >忘記密碼?</a> 
                </div> 
                <input class="loginBtn" type="button" value="登錄"/> 
            </div> 
            </form> 
        </div> 
    </div> 
</body> 
<script type="text/javascript"> 
    $(function () { 
        $('.userId,.passwordStyle').on('keyup', function (e) { 
            if (e.keyCode == 13) { 
                $('.loginBtn').trigger('click'); 
            } 
        }); 
        $('.loginBtn').on('click', function () { 
            $(".warn").hide(); 
            var pwd = $('.passwordStyle').val(); 
            if (pwd == '') { 
                $(".warn").show().html('請輸入密碼'); 
                return false; 
            } 
            var data = $("#formData").serialize(); 
            $.post("/login/checkLoginInfo", data, function (ajaxObj) { 
                //回傳內容{status: 1(success)/0(fail),} 
                if (ajaxObj.status == 0 || status == null) { 
                    $(".warn").show().html('用戶名或密碼錯誤!'); 
                } else { 
                    //登陸成功,跳轉都制定頁面 
                    window.location = '/memberCenter/index'; 
                } 
            }, "json"); 
        }); 
    }); 
</script> 
</html>

復制代碼 代碼如下:

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.Mvc; 
using System.Text; 
 
namespace bigtree.Controllers 

    using bigtree.Models; 
    using bigtree.Model; 
    using bigtree.lib; 
    using System.Net.Mail; 
    using System.Text.RegularExpressions; 
 
    public class LoginController : Controller 
    { 
        public ActionResult Index() 
        { 
            return View(); 
        } 
        /// <summary> 
        /// 檢查登陸 
        /// </summary> 
        /// <param name="f"></param> 
        /// <returns></returns> 
        [HttpPost] 
        public ActionResult CheckLoginInfo(FormCollection f) 
        { 
            try 
            { 
                //post:   user , pwd ,remembered 
                string user = f["user"].Trim(); 
                string pwd = f["pwd"].Trim(); 
                string remembered = f["remembered"].Trim(); 
 
                JsonResult res = new JsonResult(); 
                if (string.IsNullOrEmpty(user) || string.IsNullOrEmpty(pwd)) 
                { 
                    res.Data = new { status = 0 }; 
                } 
                //MD5加密后的密碼 
                pwd = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(pwd, "md5").ToLower(); 
                //從數據庫讀取 
                Common.WebUser account = MemberInfoService.GetMemberIdForCheck(user, pwd); 
                if (account == null) 
                { 
                    res.Data = new { status = 0 }; 
                } 
                else 
                { 
                    //{status: 1(success)/0(fail),} 
                    res.Data = new { status = 1 }; 
                    //todo:登陸成功,記錄登陸用戶信息保存登陸狀態 
                    FunSession.SetSession(account); 
 
                    //是否記住登錄 
                    if (remembered == "on") 
                    { 
                        HttpCookie cookie = new HttpCookie("LoginInfo", account.Id.ToString()); 
                        //3天有效 
                        cookie.Expires.AddDays(3); 
                        Response.Cookies.Add(cookie); 
                    } 
                    else 
                    { 
                        HttpCookie cookie = new HttpCookie(account.Id.ToString(), account.Id.ToString()); 
                        //使失效 
                        cookie.Expires.AddYears(-1); 
                        Response.Cookies.Add(cookie); 
                    } 
                } 
                return res; 
            } 
            catch (Exception ex) 
            { 
                throw ex.InnerException; 
            } 
        } 
    } 
}
