<>在另一篇文章中介绍了js的原生cookie应用方式，最近在工作中使用的是jquery的cookie插件，下面进行介绍，保证一会儿就学会。
一、引入jq相关文件
在html文件中引入所需文件，如下：
<script type="text/javascript" src="js/jquery-1.7.1.min.js"></script> <script
type="text/javascript" src="js/jquery.cookie.js"></script>
二、js中设置cookie
在js中设置cookie：
cookieName-------给所设置的cookie一个名称；
cookieValue-------让cookie想要保存的值，例如：$("#password").val();
{ expires: 7 }-------设置cookie的有效时间为7天，时间自己规定。
以下三行选取其中一种使用即可：
//设置cookie function setCookie(){ $.cookie("cookieName", "cookieValue", {
expires: 7 });//第一种 $.cookie('the_cookie', 'the_value', { expires: 7, path: '/'
});//第二种，增加路径 $.cookie("COOKIE_PASSWORD", $("#password").val(), "/",1/144);//示例
}
三、读取cookie
直接获取cookie值， 若cookie存在则返回所保存的’cookieValue’；若cookie不存在则返回null
//读取cookie function getCookie(){ var cookieWord=$.cookie("cookieName"); }
四、调用方法
设置和读取方法写完，在你所需要的地方直接调取方法即可。
