function iscardid(sid){ 
  var isum=0 ; 
  var info="" ; 
  if(!/^\d{17}(\d|x)$/i.test(sid)) return "你输入的身份证长度或格式错误"; 
  sid=sid.replace(/x$/i,"a"); 
  if(acity[parseint(sid.substr(0,2))]==null) return "你的身份证地区非法"; 
  sbirthday=sid.substr(6,4)+"-"+number(sid.substr(10,2))+"-"+number(sid.substr(12,2)); 
  var d=new date(sbirthday.replace(/-/g,"/")) ; 
  if(sbirthday!=(d.getfullyear()+"-"+ (d.getmonth()+1) + "-" + d.getdate()))return "身份证上的出生日期非法"; 
  for(var i = 17;i>=0;i --) isum += (math.pow(2,i) % 11) * parseint(sid.charat(17 - i),11) ; 
  if(isum%11!=1) return "你输入的身份证号非法"; 
  return true;//acity[parseint(sid.substr(0,2))]+","+sbirthday+","+(sid.substr(16,1)%2?"男":"女")
