Cookie expiration date

Question

I am not a programmer. I am trying to use a cookie script that remembers the last drop down menu selection.

I found a script that works but it does only a session co

Answer 1

This is for setting the expiry date in terms of minutes(5 minutes here)

function setCookie(cname, cvalue, exdays) {     
  var d = new Date();
  d.setTime(d.getTime() + exdays * 60 * 1000);
  var expires = "expires="+d.toUTCString();

}

function getCookie(cname) {        
  var name = cname + "=";
  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);
    }
    if (c.indexOf(name) == 0) {
      return c.substring(name.length, c.length);
    }
  }
  return "";
}
function checkCookie() {
  var user = getCookie("username");
  if (user != "") {
     //your code goes here
  } else {
     //your code goes here
    if (user != "" && user != null) {
      setCookie("username", user, 5);
    }
  }
}
