简单使用方法:
<html>  
   <head>  
     <title>JQuery-Cookie插件</title>  
     <script type="text/javascript" src="jquery-1.4.js"></script>  
     <script type="text/javascript" src="jquery.cookie.js"></script>  
   </head>  
   <body>  
     <a href="#">设置cookie1</a><br>  
     <a href="#">设置cookie2</a><br>  
     <a href="#">获取cookie</a><br>  
     <a href="#">删除cookie</a><br>  
   </body>  
 </html>  
 <script type="text/javascript">  
 $(function(){  
    var COOKIE_NAME = 'test_cookie';  
    //设置cookie,通过时间间隔  
    $('a').eq(0).click(function() {  
        $.cookie(COOKIE_NAME, 'test', { path: '/', expires: 1 });  
        return false;  
    });  
    // 设置cookie,到期时间  
    $('a').eq(1).click(function() {  
        var date = new Date();  
        date.setTime(date.getTime() + (1 * 24 * 60 * 60 * 1000));  
        $.cookie(COOKIE_NAME, 'test', { path: '/', expires: date });  
        return false;  
    });  
    // 获取 cookie  
    $('a').eq(2).click(function() {  
        alert($.cookie(COOKIE_NAME));  
        return false;  
    });  
    // 删除cookie  
    $('a').eq(3).click(function() {  
        $.cookie(COOKIE_NAME, null, { path: '/' });  
        return false;  
    });  
 });  
 </script> 

插件的源代码也很简单:
jQuery.cookie = function(name, value, options) {  
     if (typeof value != 'undefined') { // name and value given, set cookie  
         options = options || {};  
         if (value === null) {  
             value = '';  
             options.expires = -1;  
         }  
         var expires = '';  
         if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) {  
             var date;  
             if (typeof options.expires == 'number') {  
                 date = new Date();  
                 date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));  
             } else {  
                 date = options.expires;  
             }  
             expires = '; expires=' + date.toUTCString();  
         }  
         var path = options.path ? '; path=' + (options.path) : '';  
         var domain = options.domain ? '; domain=' + (options.domain) : '';  
         var secure = options.secure ? '; secure' : '';  
         document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');  
     } else {  
         var cookieValue = null;  
         if (document.cookie && document.cookie != '') {  
             var cookies = document.cookie.split(';');  
             for (var i = 0; i < cookies.length; i++) {  
                 var cookie = jQuery.trim(cookies[i]);  
                 if (cookie.substring(0, name.length + 1) == (name + '=')) {  
                     cookieValue = decodeURIComponent(cookie.substring(name.length + 1));  
                     break;  
                 }  
             }  
         }  
         return cookieValue;  
     }  
 };
