[prash21m]

Hi there,

I have a php script that contain java script codes to show pop up email registration form, but these codes does not work. can anybody suggest me how to make it to work ? Below is the code that i have on my script.

**Maybe to set cookie : **

<script type="text/javascript"> 
function ReadCookie(cookieName) { 
var theCookie=" "+document.cookie; 
var ind=theCookie.indexOf(" "+cookieName+"="); 
if (ind==-1) ind=theCookie.indexOf(";"+cookieName+"="); 
if (ind==-1 || cookieName=="") return ""; 
var ind1=theCookie.indexOf(";",ind+1); 
if (ind1==-1) ind1=theCookie.length; 
return unescape(theCookie.substring(ind+cookieName.length+2,ind1)); 
} 

function SetCookie(cookieName,cookieValue,nDays,domain) { 
var today = new Date(); 
var expire = new Date(); 
if (nDays==null || nDays==0) nDays=1; 
expire.setTime(today.getTime() + 3600000*nDays); 
if(domain != ''){ 
document.cookie = cookieName+"="+escape(cookieValue) + ";expires="+expire.toGMTString()+";domain="+domain+";path=/"; 
}else{ 
document.cookie = cookieName+"="+escape(cookieValue) + ";expires="+expire.toGMTString(); 
} 
} 
</script>
