cookie-util

自己写的一个cookie-util，支持json

 1 (function (name, factory) {
 2     if (typeof define === 'function') {
 3         define(factory);
 4     } else if (typeof module !== 'undefined' && module.exports) {
 5         module.exports = factory();
 6     } else {
 7         this[name] = factory(this[name]);
 8     }
 9 })('cookie', function (originalCookie) {
