我正在研究JavaScript手风琴，不知何故，我开始定位手风琴ID而不是<li>
基本上，如果有两个像这样的标记
，我想在下面生成两个手风琴<div id="st-accordion" class="st-accordion">
<ul>
<li>
<a href="#">{tag_name_nolink}</a>
<div class="st-content">
{tag_Partners Module tag}
</div>
</li>
</ul>
</div>
如果有两个<div id="st-accordion" class="st-accordion">.......</div>那么它应该显示两个有效的手风琴，但是当div中有两个<li>时，它会制作两个有效的手风琴。
这是JS和Fiddles

答案 0 :(得分：4)
你有2个具有相同ID的元素，ID必须是唯一的，所以你要做的就是使用class而不是ID：
$(function() {
$('.st-accordion').accordion({
oneOpenedItem : true
});
});
这是jsFiddle
