Jquery+$.cookie()实现跨越页面tabs导航

---------tabs.js-----------------

$(function(){

       //init seleted tab
       var on= $.cookie('current_tab');
       if(on!="" && !isNaN(on))
       {
           $(".nav li").eq(on).addClass("on").siblings().removeClass();
       }
       //default tab
       else
       { $.cookie('current_tab', 0); }

       //change tab
       $(".nav li").click(function(){
           var current_tab = $(".nav li").index(this);
           $.cookie('current_tab', current_tab);
           window.location = $(this).attr("href");
       });

})

---------------css.css----------------------

.nav { overflow:hidden; height:20px;}
.nav li { float:left; display:inline; padding:3px;}
.nav li a:hover { color:yellow; }
.nav li.on { background:#900; color:#FFF;}
.nav li.on a { color:#fff; }
.nav li.on a:hover { color:yellow; }
a { text-decoration:none; }

其它两个页面一样，文件改一下可以了
