jQuery Carousel跳转到错误的项目

我的皮肤有知觉问题 :last .before() 方法不在最后一个元素之前插入代码。

我想出了一个新问题 :/

问题是(既然 <li> ,旋转木马现在将滚动4个项目,但它们会快速跳转到下一个项目。

代码如下。 (另外,我认为是这样的: $('#carousel_ul').css({'left' : '0px'}); 19 一 37 .

非常感谢。

$(document).ready(function () { 
    var numItems = $('#carousel_ul').find('li');
    var visibleItems = 4;
    var difference = visibleItems % numItems.length;

    $('#carousel_ul li').last().before($('#carousel_ul li:last')+$('#carousel_ul li:last')); 

    while (difference > 1) {
        $('#carousel_ul li:last').after('<li class="empty" style="background-color: green;"></li>');
        difference--;
    }

    $('#right_scroll a').click(function(){
        var item_width = $('#carousel_ul li').outerWidth() + 10;
        var left_indent = parseInt($('#carousel_ul').css('left')) - (item_width * 4);

        $('#carousel_ul:not(:animated)').animate({'left' : left_indent},1500,function(){    
            $('#carousel_ul li:last').after($('#carousel_ul li:first')); 
            $('#carousel_ul').css({'left' : '0px'}); //error here?
        }); 
        return false;
    });

    $('#carousel_ul li').each(function(intIndex) {
        var itemName = $(this).attr('name');
        $(this).html(itemName);
        console.log(itemName);
    });

    $('#left_scroll a').click(function(){

        var item_width = $('#carousel_ul li').outerWidth() + 10;
        var left_indent = parseInt($('#carousel_ul').css('left')) + (item_width * 4);

        $('#carousel_ul:not(:animated)').animate({'left' : left_indent},1500,function(){     
            $('#carousel_ul li:first').before($('#carousel_ul li:last')); 
            $('#carousel_ul').css({'left' : '0px'}); //error here?
        });
        return false;
    });
    $('#tabcontainer > ul').tabs();
});
