Get Cookie function Getcookievalue (cookiename) {var cookievalue = Document.cookie; var cookiestartat = Cookievalue.index Of ("" "+cookiename+" = "); if (cookiestartat==-1) {cookiestartat = Cookievalue.indexof (cookiename+ "=");} if (cookiestartat==-1) {cookieValue = Null else {cookiestartat = Cookievalue.indexof ("=", Cookiestartat) +1; cookieendat = Cookievalue.indexof (";", cookieStartAt ); if (cookieendat==-1) {cookieendat = cookievalue.length;} cookievalue = Unescape (cookievalue.substring (CookieStartAt, Cookieendat));//Decode latin-1} return cookievalue; }
