Json的Jquery cookie插件

Question

我使用jquery-plugin保存数据，用户点击：

$(document).ready(function(){
    $('a.close').click(function(){
        $.cookie.json = true;

        var user = $('article.user').html();
        var text = $('article.text').html();
        var pic = $('img.profilePicture').attr('src');

        var data = { user:"user" , text:"text" , pic:"pic" };

        $.cookie('the_cookie' , data , {expires: 7, path: "/", domain: "domain.com"})

        var lastSeen = $.cookie('the_cookie');

        user = lastSeen.user;
        text = lastSeen.text;
        pic = lastSeen.pic;

        $('.last_seen_user').html(user);
        $('.last_seen_text').html(text);
        $('.last_seen_image_1').attr('src',pic);
    });
});

但是数据没有保存，即使我使用＆＃34; json＆＃34;，任何人都可以帮我解决这个问题？问候！
