这是在截取的登陆功能代码
count = document.cookie.split(\';\')[0];//以分号为分隔符对cookie进行分割alert(document.cookie.split(\';\')[0]);取出--count=3
if(count.split(\'=\')[1] >= 3){//alert(document.cookie.split(\'=\')[1]);取出--3;PHPSESSID
alert(\'因为您的非法操作,您将无法再执行登录操作\');
return false;
}
$(\'regimg\').style.visibility = "visible";
url = \'login_chk.php?act=\'+(Math.random())+\'&name=\'+$(\'lgname\').value+\'&pwd=\'+$(\'lgpwd\').value;
xmlhttp = new XMLHttpRequest();
xmlhttp.open(\'get\',url,true);
xmlhttp.onreadystatechange = function(){
if(xmlhttp.readyState == 4&& xmlhttp.status == 200){
msg = xmlhttp.responseText;
//msg即是login_chk.php里面的reback???
if(msg == \'0\'){
alert(\'您还没有激活,请先登录邮箱进行激活操作。\');
}else if(msg == \'1\'){
alert(\'用户名或密码输入错误,您还有2次机会\');
$(\'lgpwd\').select();
}else if(msg == \'2\'){
alert(\'用户名或密码输入错误,您还有1次机会\');
$(\'lgpwd\').select();
}else if(msg == \'3\'){
alert(\'因为登录次数过多,您的帐号已被冻结,请联系管理员\');
$(\'lgname\').select();
}else if(msg == \'4\'){
alert(\'用户名输入错误\');
$(\'lgname\').select();
}else if(msg == \'-1\'){
alert(\'登录成功\');
location = \'main.php\';
}else{
alert(msg);
}
$(\'regimg\').style.visibility = "hidden";
}
}
xmlhttp.send(null);
}
这是处理数据的代码
count = document.cookie.split(\';\')[0];//以分号为分隔符对cookie进行分割alert(document.cookie.split(\';\')[0]);取出--count=3
if(count.split(\'=\')[1] >= 3){//alert(document.cookie.split(\'=\')[1]);取出--3;PHPSESSID
alert(\'因为您的非法操作,您将无法再执行登录操作\');
return false;
}
$(\'regimg\').style.visibility = "visible";
