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)

}
else

}
}

{
chklogin(context);
}
else if (action == "logout")
{
logout(context);
}
else if (action == "autologin")
{
autologin(context);
}
}

这就是用户的登陆，希望对你有帮助！
