用js向cookie中儲存資料、獲取資料的方法如下： function GetCookieVal(offset) //獲得Cookie解碼後的值 { var endstr = document.cookie.indexOf (";", offset); if (endstr == -1) endstr = document.cookie.length; return unescape(document.cookie.substring(offset, endstr)); } //--------------------------- function SetCookie(name, value) //設定Cookie值 { var expdate = new Date(); var argv = SetCookie.arguments; var argc = SetCookie.arguments.length; var expires = (argc > 2) ? argv[2] : null; var path = (argc > 3) ? argv[3] : null; var domain = (argc > 4) ? argv[4] : null; var secure = (argc > 5) ? argv[5] : false; if(expires!=null) expdate.setTime(expdate.getTime() + ( expires * 1000 )); document.cookie = name + "=" + escape (value) +((expires == null) ? "" : ("; expires="+ expdate.toGMTString())) +((path == null) ? "" : ("; path=" + path)) +((domain == null) ? "" : ("; domain=" + domain)) +((secure == true) ? "; secure" : ""); } //--------------------------------- function DelCookie(name) //刪除Cookie { var exp = new Date(); exp.setTime (exp.getTime() - 1); var cval = GetCookie (name); document.cookie = name + "=" + cval + "; expires="+ exp.toGMTString(); } //------------------------------------ function GetCookie(name) //獲得Cookie的原始值 { var arg = name + "="; var alen = arg.length; var clen = document.cookie.length; var i = 0; while (i
