cookie使用

竟然没有全局配置过cookie，见鬼

设置：

var setCookie = function(name, value) {
         var Days = 30;
         var exp = new Date();
         exp.setTime(exp.getTime() + Days * 24 * 60 * 60 * 1000);
         document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString();
         //$cookies[name] = value;
        };

var getCookie = function(name) {
  var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)");
  if (arr = document.cookie.match(reg))
   return unescape(arr[2]);
  else
   return null;
 }

setCookie('name','老李')
getCookie('name')
