登录界面
<form name="frmLogin" method="post" action="/sso/login.do?cmd=0" onSubmit="return checkForm();">
内置一个隐藏字段
        function checkCookie(){
                document.cookie = 'testcookie' + escape('nothing')
                if (document.cookie == "") {
                        cookieMess.innerHTML = "本站要求您的浏览器支持cookie功能，\n\n否则将会影响您在本站的正常使用！";
                }
        }
       
        function checkForm(){

                if(document.frmLogin.login_name.value==""){
                        alert("请填写用户名！");
                        document.frmLogin.login_name.focus();
                        return false;

                }
                return true;
        }

更新了隐藏字段cookie_flag.

checkCookie的作用<font id=cookieMess></font>

cookie_flag=true&login_name=ciciv12345&password=123456789&rand=3288&btn_login=%B5%C7%C2%BC
在此里面强制添加了testcookienothing。

导致cookie_flag为true。
通过赋值给document.cookie来检查是否支持cookie。
