Merhaba,
Elimde 24 saatte acılan popup kodu var fakat bunu her üyenin 1 defa görmesini istiyorum.

Bunu nasıl yaparım?

<SCRIPT LANGUAGE="JavaScript">
<!--  
//frequency cap,1 pop-under per number of hours
var frequencyCap = 24; //hours 
function setCookie(cookieName,cookieValue, expirehours) {
  if (frequencyCap > 0){
    var today = new Date();
    var expire = new Date();
     expire.setTime(today.getTime() + 1600000 * frequencyCap);
     document.cookie = cookieName+"="+escape(cookieValue)
                 + ";expires="+expire.toGMTString() + "; path=/";
  }else{
     document.cookie = cookieName+"="+escape(cookieValue) + "; path=/";
  }
// nurettin
}
function ReadCookie(cookieName) {
 var theCookie=""+document.cookie;
 var ind=theCookie.indexOf(cookieName);
 if (ind==-1 || cookieName=="") return ""; 
 var ind1=theCookie.indexOf(';',ind);
 if (ind1==-1) ind1=theCookie.length; 
 return unescape(theCookie.substring(ind+cookieName.length+1,ind1));
}
if (ReadCookie('erttrarrtyyrr1') != 'yes')  
{ 
 setCookie('erttrarrtyyrr1','yes', frequencyCap); 
 document.write('<SCRI'+'PT LANGUAGE="JavaScript1.1" '); 
 document.write(' SRC="http://www.site.com/pop.js">');
 document.write('</SCR'+'IPT>'); 
} 
// --> 
</SCRIPT>
