jQuery.cookie.js download:https://github.com/carhartl/jquery-cookie/

First let’s learn how to use cookie.js.

First import:

<script type="text/javascript" src="js/jquery-1.8.3.js"></script><!--jQuery版本最好是1.3.1以上-->
<script type="text/javascript" src="js/jquery.cookie.js"></script>

Then you can use it.

$.cookie(&#39;the_cookie&#39;); //读取Cookie值
$.cookie(&#39;the_cookie&#39;, &#39;the_value&#39;); //设置cookie的值
$.cookie(&#39;the_cookie&#39;, &#39;the_value&#39;, {expires: 7, path: &#39;/&#39;, domain: &#39;example.com&#39;, secure: true});//新建一个cookie,"expires"是有效天数,"path"是保存路径,"domain"是创建 cookie的网页所拥有的域名,"secure"是cookie的传输是否使用安全协议（HTTPS）
$.cookie(&#39;the_cookie&#39;, &#39;the_value&#39;); //新建cookie
$.cookie(&#39;the_cookie&#39;, null); //删除一个cookie

.huanFu ul li.select{border:3px solid #000;margin-top:-3px;}
</style>
<script>
$(function(){
  $(".huanFu ul li").on("click",function(){
    var piFu=$(this).attr("fuName");//取得选择皮肤的fuName值
    $("body").attr("class",piFu);//给body有class加上fuName值，也就是添加对应的背景色
    $(this).addClass("select").siblings().removeClass("select");//选择中的li才有大黑框选中，其余去除大黑框选中效果
    $.cookie("MySkin",piFu,{path:&#39;/&#39;,expires:10});//创建cookie,并保存到本地cookie中
  });
  var cookieSkin=$.cookie("MySkin");//取出本地cookie中的保存的值
  if(cookieSkin){
    $(".huanFu ul li[fuName=&#39;"+cookieSkin+"&#39;]").addClass("select").siblings().removeClass("select");//选择中的li才有大黑框选中，其余去除大黑框选中效果
    $("body").attr("class",cookieSkin);//给body有class加上fuName值，也就是添加对应的背景色
  }else{
    $("body").attr("class","fu1");//如果本地cookie无记录，就默认用红色做背景
  }
});
</script>
</head>
<body class="fu1">
  <p class="huanFu">
    <ul>
      <li class="fu1" fuName="fu1"></li>
      <li class="fu2" fuName="fu2"></li>
      <li class="fu3" fuName="fu3"></li>
      <li class="fu4" fuName="fu4"></li>
    </ul>
  </p>
</body>
