首先引入jquery.cookie.js

jquery.cookie.js下地址：

操作文档：

创建cookies：

$.cookie('name', 'value');

设置有效期：

设置七天过期$.cookie('name', 'value', { expires: 7 });设置cookie一小时后过期var cookietime = new Date(); cookietime.setTime(date.getTime() + (60 * 60 * 1000));//coockie保存一小时 $.cookie("example", "foo",{expires:cookietime});

设置路径：

$.cookie('name', 'value', { expires: 7, path: '/' });

读取cookies：

$.cookie('name'); // => "value"$.cookie('nothing'); // => undefined

读取所有的cookies： 

$.cookie(); // => { "name": "value" }

删除cookies：

// Returns true when cookie was successfully deleted, otherwise false$.removeCookie('name'); // => true$.removeCookie('nothing'); // => false// Need to use the same attributes (path, domain) as what the cookie was written with$.cookie('name', 'value', { path: '/' });// This won't work!$.removeCookie('name'); // => false// This will work!$.removeCookie('name', { path: '/' }); // => true
