form表单提交

 <form class="form" id="mainform" action="/Home/Login" method="post">
                    <input type="text" placeholder="Username" id="UserName" name="UserName">
                    <input type="password" placeholder="Password" id="PassWord" name="PassWord">
                    <button type="submit" id="login-button">Login</button>
                </form>

//后台代码
  [HttpPost]
        public ActionResult Login(UserInfo user)
        {
            return Redirect("/Home/Index");
        }

 <form class="form" id="mainform" action="/Home/Login" method="post">
                    <input type="text" placeholder="Username" id="UserName" name="UserName">
                    <input type="password" placeholder="Password" id="PassWord" name="PassWord">
                    <input type="button" name='onLogin' value="登陆" onclick="onLogin()">
                </form>

//js代码
 function onLogin() {
            if ($("#UserName").val() == "" && $("#PassWord").val() == "") {
                $.messager.alert("提示", "请输入账号和密码！");
                return;
            }
            var para = $("mainform").serialize();
            $.ajax({
                type: "POST",
                url: "/Home/Login",
                data: para,
                dataType: "json",
                success: function (d) {
                    if (d.indexOf("OK") > -1) {
                        document.location.href = "/Home/Index";
                    }
                    else {
                        $.messager.alert("账号或密码不正确");
                    }
                }
            });
        }
