C#中通过js实现个人用户和非个人用户的登陆

实现用户的登录功能，这里举一个个人和非个人用户的登录的例子

前台代码：

<ul class="login_list clearfix">
                    <li>
                        <input class="input_one" type="text" id="txtusername" placeholder="请输入帐号">

                    </li>
                    <li>
                        <input class="input_two" type="password" id="txtuserpwd" placeholder="请输入密码">

                    </li>
                    <li class="forget">
                        <input type="checkbox">
                        <span> 记住用户名</span >
                    </li>
                    <li class="dis">
                        <input class="check" placeholder="验证码" type="text" />
                        <img src="" />
                    </li>
                    <li class="lastt">< a class ="fr" href ="/about/zhmm.html" target ="_blank">忘记密码？</a ><span> 没有帐号？</span ><a class="zc" href="/reg.html" target="_blank"> 注册</a ></li>
                    <li class="msg">< em id ="msg"></em></ li>
                    <li class="dr">< a href ="javascript:void(0);" onclick ="userlogin();" class="un"> 登录</a ></li>
                </ul>

　　引用JS文件lo_re.js（判断为不为空，为空的话提示消息）：

function userlogin()
{
    var UserName=$("#txtusername" );
        if($.trim(UserName.val())==""){
            UserName.focus();
           $( "#msg").html(" 帐号不能为空！ ");
            return;
        } else{
            $( "#msg").html("" );
        }
        var UserPwd=$("#txtuserpwd" );
        if($.trim(UserPwd.val())=="" ){
            UserPwd.focus();
            $( "#msg").html(" 密码不能为空！ ");
            return;
        } else{
            $( "#msg").html("" );
        }
       $.post( "/JsData/userlogin.ashx" , { action: "login", username: UserName.val(),userpwd:UserPwd.val(), time: new Date().getTime() }, function(msg) {
            var data = eval("(" + msg + ")");
            var state=parseInt(data[0].state);
            if(state==1){
                if(data[0].UserType=="0" ){ //非个人用户
                   $.cookie( "UserType", "0" , { path: "/" });
                   $.cookie( "UserName", data[0].UserName, { path: "/" });

               } else{// 个人用户
                                      alert("恭喜您，登陆成功"); //登陆完成之后，会弹出此消息框提示（要在判断用户名、密码是否正确之后才能弹出此消息框）
                   $.cookie( "UserType", "1" , { path: "/" });
                   $.cookie( "UserID", data[0].id, { path: "/" });
               }
               location.href= "/";

            } else{
                 $( "#msg").html(" 账号或密码错误！ ");
            }
        });
}

　　/JsData/userlogin.ashx的文件中（这是一个判断的过程，确认传过来的值是登陆还是别的，如果是登陆的话，验证用户名和密码并返回数据）：

usersDAL ud = new usersDAL ();
        protected string action = CRequest.GetString( "action");
        schoolsDAL sd = new schoolsDAL();
        schoolsModel sm = new schoolsModel();
        protected int cookie = CRequest.GetInt( "cookie",1);
        protected string username = CRequest.GetString( "username");
        public void ProcessRequest(HttpContext context)
        {

                if (action == "login" )
                {
                    if (username.IndexOf("@" ) != -1)
                    {
                        login(context);
                    }
                    else
                    {
                        wxlogin(context);
                    }
                }
                else if (action == "chklogin")
                {
                    chklogin(context);
                }
                else if (action == "logout")
                {
                    logout(context);
                }
                else if (action == "autologin")
