codice:
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = '; expires='+date.toGMTString();
}
else expires = '';
document.cookie = name+'='+value+expires+'; path=/';
}
// x settarlo:
// createCookie('tuocookie','ok',365);
function readCookie(name) {
var nameEQ = name + '=';
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
function goThere(){
if(!document.theForm.theMenu.selectedIndex==""){
if(readCookie('tuocookie')=="ok"){
window.open(document.theForm.theMenu.options[document.theForm.theMenu.selectedIndex].value,theTarget,"");
}
else {
alert('non puoi scaricare');
}
}
}
