you should try this code for popunder:
PHP Code:
<script type="text/javascript">
var popURL = 'http://www.url.com;
var pop = 1;
function redir() { setTimeout("pdv()", 3000); pop=0; }
function pdv() { window.location = popURL; }
</script>
this one for popunder opened only after one click on your page :
PHP Code:
<script type="text/javascript">
function ScanCookie(variable)
{
cook = document.cookie;
variable += "=";
place = cook.indexOf(variable,0);
if (place <= -1)
return("0");
else
{
end = cook.indexOf(";",place)
if (end <= -1)
return(unescape(cook.substring(place+variable.length,cook.length)));
else
return(unescape(cook.substring(place+variable.length,end)));
}
}
function CreationCookie(nom,valeur,permanent)
{
if(permanent)
{
dateExp = new Date(2020,11,11);
dateExp = dateExp.toGMTString();
ifpermanent = '; expires=' + dateExp + ';';
}
else
ifpermanent = '';
document.cookie = nom + '=' + escape(valeur) + ifpermanent;
}
function load_pop_power()
{
if(ScanCookie("ex")==0)
{
win2 = window.open("http://www.url.com",'_blank',"top=60, left=60, width=900, height=900, scrollbars=1, resizable=1, toolbar=1, location=1, menubar=1, status=1, directories=1");
win2.blur()
window.focus()
CreationCookie("ex","oui",false)
}
}
</script>
