    });

    function switchStylestyle(styleName)
    {
        $('link[rel*=style][title]').each(function(i)
        {
            this.disabled = true;
            if (this.getAttribute('title') == styleName) this.disabled = false;
        });
        createCookie('style', styleName, 365);
    }
})(jQuery);

function createCookie(name,value,days)
{
    if (days)
    {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    }
    else var expires = "";
    document.cookie = name+"="+value+expires+"; path=/";
}
function readCookie(name)
{
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++)
    {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}
function eraseCookie(name)
{
    createCookie(name,"",-1);
}

效果虽然有了,但有点看不懂,求解释~~~
