Cookie in Java Script

can we store multiple value in cooking through javascript ???

like as  i am trying to do in below code segment...

 

if (document.frmRegistration.txtName.value!="" && document.frmRegistration.txtAge.value!="")
{
cookieName= escape(document.frmRegistration.txtName.value) + ";";
cookieAge=escape(document.frmRegistration.txtAge.value)+";";
document.cookie="name="+cookieName+";age="+cookieAge+";";
document.write("Name="+cookieName+"Age="+cookieAge);

}
