jquery cookie for css style switcher

Question

我正在尝试在jquery中成功制作样式表切换器，但是当我尝试使用jquery.cookie插件将更改保存在cookie中时，它不起作用。

下面是 jquery 代码：

$("#theme-cp ul li").click(function () {
    var $pattern = $(this).css("background-image");
    $("body").css("background-image",$pattern);
    $("#main-wrapper").css("background-image",$pattern);
    $.cookie('background',$pattern);
    alert($.cookie('background'));
});

警报是为了检查，但它不起作用....

我最近做了同样的事情，我让它工作，我想我会和你分享我的代码。

jQuery

//If Cookie isn't blank (i.e. do we have a cookie set at all?)
if($.cookie('colour')!='')
{
    $('body').addClass($.cookie('colour'));  //set the body to the cookie colour
}
$('#accessibility-colours a').each(function(index)
{
    $(this).click(function(e)
    {
        e.preventDefault();
        switch(index)
        {
            //black text white background
            case 0:
                $('body').removeClass($.cookie('colour'));
                $('body').addClass('blackText-whiteBackground');
                $.cookie('colour', null);
                $.cookie('colour', 'blackText-whiteBackground',{ expires: 7, path: '/' });
            break;
            //black text yellow background
            case 1:
                $('body').removeClass($.cookie('colour'));
                $('body').addClass('blackText-yellowBackground');
                $.cookie('colour', null);
                $.cookie('colour', 'blackText-yellowBackground',{ expires: 7, path: '/' });
            break;
            //black text pink background
            case 2:
                $('body').removeClass($.cookie('colour'));
                $('body').addClass('blackText-pinkBackground');
                $.cookie('colour', null);
                $.cookie('colour', 'blackText-pinkBackground',{ expires: 7, path: '/' });
            break;
            //blue text white background
            case 3:
                $('body').removeClass($.cookie('colour'));
                $('body').addClass('blueText-whiteBackground');
                $.cookie('colour', null);
                $.cookie('colour', 'blueText-whiteBackground',{ expires: 7, path: '/' });
            break;
        }
    });
