有没有办法通过jquery添加一个类到包含ul的所有div只有一个列表元素(如div.filter_7).使用jQuery,我需要遍历每个div.list-container并计算列表元素.如果列表元素低于2,那么jquery应该附加一个类.

<div class="filter_group">
<div class="filter-holder filter_1">
<h4>Test</h4>
<div class="list-container">
    <ul class="list filter">
        <li class="list_id1">list_id1</li>
        <li class="list_id2">list_id2</li>
        <li class="list_id3">list_id3</li>
        <li class="list_id4">list_id4</li>
        <li class="list_id5">list_id5</li>
    </ul>
</div>
</div>
<div class="filter-holder filter_2">
<h4>Test</h4>
<div class="list-container">
    <ul class="list filter">
        <li class="list_id11">list_id11</li>
        <li class="list_id22">list_id22</li>
        <li class="list_id33">list_id33</li>
        <li class="list_id44">list_id44</li>
        <li class="list_id55">list_id55</li>
    </ul>
</div>
</div>
<div class="filter-holder filter_6">
<h4>Test</h4>
<div class="list-container">
    <ul class="list filter">
        <li class="list_id111">list_id111</li>
        <li class="list_id222">list_id222</li>
        <li class="list_id555">list_id555</li>
    </ul>
</div>
</div>
<div class="filter-holder filter_7">
<h4>Test</h4>
<div class="list-container">
    <ul class="list filter">
        <li class="list_id1111">list_id1111</li>
        <li class="list_id2221">list_id2222</li>
    </ul>
</div> …

我想将SELECT/OPTION与UNORDERED LIST结合用于jQuery同位素组合滤波器.我让它使用多个SELECT/OPTION,但无法弄清楚如何结合SELECT和UL.有帮助吗？
