我正在使用显示/隐藏来显示基于它们的类属性的项目组。如何进一步过滤这些项目组，以便在 B 列中单击的第二个结果集是第一个结果集的子集。根据我的阅读，我认为过滤器或兄弟可能是关键，但到目前为止我的实验失败了。

在这里，我将更新所需功能的更多解释：单击第一个列表中的项目以显示该列表的子集。单击第二个列表中的项目以细化前一个子集。例如，在第 1 列中，单击红色以仅查看红色项目。然后在第 2 列中，单击大以仅查看大的红色项目。仍在第 2 列时，单击小以仅查看小的红色项目。应该可以通过这种方式进行过滤，直到单击返回到应该显示该列表的新子集的第一列。

这个小提琴会起作用

$('li').click(function() {
  var divs = $('item div:visible').add('.' + this.id + ':visible');
  $('.item div').hide();
  divs.show('slow');
});

我建议在 this fiddle中使用闭包，因此您无需div在每次点击时重新选择 's。除非它们是动态的。

$(document).ready(function() {
  var squares = $('.item div');
  $('li').click(function() {
    var divs = $(':visible', squares).add('.' + this.id + ':visible');
    squares.hide();
    divs.show('slow');
  });
});​

根据 OP 的编辑：

这个小提琴会奏效。

$(document).ready(function() {
  var squares = $('.item div');
  var filters = $('.nav').data('filter', null);
  $('li').click(function(){
    $(this).closest('.nav').data('filter', '.' + this.id);
    var f = filters.map(function(){ return $(this).data('filter'); }).toArray();
    squares.hide().filter(f.join('')).show('slow');
  });
});​

注意：按照代码的编写方式，您应该能够添加n额外的过滤器。

我已将 A 列设置为第一个过滤器，然后是 B 列。因此，如果您单击 A 然后 B，您将获得一个过滤器，然后是该子集上的另一个过滤器。

JAVASCRIPT

$(document).ready(function() {
    $('li').click(function(e) {
        console.log($(e.target).parents('div').attr('id'));
        if($(e.target).parents('div').attr('id') == 'filter1'){
            $('.item div').hide();
            $('.' + this.id).show('slow');
        }else if($(e.target).parents('div').attr('id') == 'filter2'){
            console.log('.item div.' + this.id);
            var keepShown = $('.item div.' + this.id);
            $('.item div').not(keepShown).hide('slow');    
        }

    });
});

我使用keepShown变量来查找第二组（B 列），然后隐藏第二组中未显示的任何内容。
