Question

我想突出显示当前项目，如何获取图像源和当前缩略图？ http://jsfiddle.net/RL8MV/2/

$('#carousel span').append('<img src="http://coolcarousels.frebsite.nl/c/28/img/gui/carousel_glare.png" class="glare" />');
                $('#thumbs a').append('<img src="http://coolcarousels.frebsite.nl/c/28/img/gui/carousel_glare_small.png" class="glare" />');

                $('#carousel').carouFredSel({
                    responsive: true,
                    circular: false,
                    auto: true,
                    items: {
                        visible: 1,
                        width: 200,
                        height: '56%'
                    },
                    scroll: {
                        fx: 'directscroll'
                    }
                });

                $('#thumbs').carouFredSel({
                    responsive: true,
                    circular: true,
                    infinite: true,
                    auto: {
                        play:true
                    },
                    scroll:
                    {
                        items: 1,
                        onBefore: function() {

                            var pos = $("#thumbs").triggerHandler("currentPosition");
                           // alert( "The carousel is at item number " + pos );


                        }

                    },
                    prev: '#prev',
                    next: '#next',
                    items: {
                        visible: {
                            min: 2,
                            max: 6
                        },
                        width: 150,
                        height: '66%'
                    }
                });

                $('#thumbs a').click(function() {
                    $('#carousel').trigger('slideTo', '#' + this.href.split('#').pop() );
                    $('#thumbs a').removeClass('selected');
                    $(this).addClass('selected');
                    return false;
                });

您可以通过添加以下内容来获取图像的来源：

var src = $(this).children('img').attr('src');

$('#thumbs a').click(function() {
  var src = $(this).children('img').attr('src'); 

  $('#carousel').trigger('slideTo', '#' + this.href.split('#').pop() );
  $('#thumbs a').removeClass('selected');
  $(this).addClass('selected');
  return false;
});

你会为当前的缩略图做同样的事情，你只需要在缩略图持有者上调用'src'attr
