步步为营-85-注册信息验证

注册信息验证:

1 前台验证(js+Ajax):

首先像"邮箱格式","非空"验证可以通过js+正则表达式来完成;

另外像"用户名是否存在","邮箱是否已使用"可通过 Ajax向后台页面发请求,实现无页面刷新的验证()

2 仅仅是前台验证会存在一定的安全隐患,所以当用户提交时候还要实现后台验证

<form id="formRegister" name="formRegister" method="post">
    <table width="80%" height="22" border="0" align="center" cellpadding="0" cellspacing="0" id="tableRegister">
        <tr>
            <td width="2" bgcolor="#DDDDCC">&nbsp;</td>
            <td>
                <div align="center">
                    <table height="61" cellpadding="0" cellspacing="0" style="height: 332px">
                        <tr>

注意 验证"邮箱"的时候有一句

 $.post("/ashx/ValidateReg.ashx", { "action": "mail", "userMail": val }, function (data) {
                        $("#msgEamil").css("display", "inline");
                        warnMsg("#msgEamil", data);
                    });

            string action = context.Request["action"];
            if (action == "mail")

                return false;
            }
        }
    }
}

另外当点击"注册"按钮后,将表单元素序列化为json数组对象

 var par = $("#aspnetForm").serializeArray();                

par = JSON.stringify(par);

$.post("/ashx/UserRegister.ashx", { "parameter": par }, function (data) {                     alert(data);                 });

需要在后台引用 命名空间来实现反序列化

using Newtonsoft.Json.Linq;

  JArray ja = (JArray)JsonConvert.DeserializeObject(jsonStr);//反序列化
