/**存放Cookies: 两个参数，一个是cookie的名子，一个是值*/function SetCookie(name,value){var Days = 30; //此 cookie 将被保存 30 天var exp  = new Date();//new Date("December 31, 9998");exp.setTime(exp.getTime() + Days*24*60*60*1000);document.cookie = name + "="+ escape (value) + ";expires="+exp.toGMTString();}/**取cookies函数 */function getCookie(name){var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));if(arr != null) return unescape(arr[2]); return null;}/**删除cookie*/function delCookie(name){var exp = new Date();exp.setTime(exp.getTime() - 1);var cval=getCookie(name);if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();}

这里有一个读取php设置的二维数组的cookie

//可以应对二维数组的cookiefunction getCookie(name) {    var ret = {};   var cookie = document.cookie.split(';');   for (var i = 0; i < cookie.length; i++) {   var s = cookie[i].split('=');   ret[s[0].replace(/(^\s*)|(\s*$)/g, "")] = s[1].replace(/(^\s*)|(\s*$)/g, "");   }   if (name in ret)   return ret[name];   return null;}
