cookie netscape 7

[tom]

Dieses Script funktioniert nur im ie:

es sollen Künstler als cookie gemerkt werden, eas muß ich ändern um es in netscape 7 funtionstüchtig zu machen???
var field = "artists="
var isIE = false
var isNN = false
var isDOM = false;
var isDomIE = false;
var isDomNN = false;
var layerok = false;
if (parseInt(navigator.appVersion)>=3) {
 var n = navigator.appName
  if (n == "Microsoft Internet Explorer") isIE = true
  if (n == "Netscape") isNN = true
  if (n == "Netscape") isDomNN = true

}

function getArtists() {
 cookie = document.cookie
 var i = cookie.indexOf(field)
 if (i == -1)
  return ''
 var j = cookie.indexOf(";", i)
 if (j == -1)
  j = cookie.length
 return unescape(cookie.substring(i+field.length,j))
}

function setArtist(artist) {
 old_cookie = getArtists()
 if (old_cookie == '') {
  sep = ''
 } else {
  sep = ','
 }
 if (old_cookie.indexOf(artist) != -1)
  return
 old_cookie += sep+artist
 document.cookie = field+old_cookie+";PATH=/";
}

function clearArtists() {
 document.cookie = "artists=;PATH=/";
}

function putArtists() {
 theArtist = getArtists()
 a = theArtist.split(',')
 theArtist = a.join('\n')
 if (isNN) {
  document.LayoutLYR.document.KunstForm1.kuenstlerfeld.value = theArtist
 }
 if (isIE) {
  document.KunstForm1.kuenstlerfeld.value = theArtist
 }
}
