我有这样的 div 结构
<div class="items">
<div class="itemRow">
<div class="item">
<div class="item">
<div class="item">
</div>
<div class="itemRow">
<div class="item">
<div class="item">
<div class="item">
</div>
</div>
如何让它们合并/组合两个 div“itemRow”?变成这样
<div class="items">
<div class="itemRow">
<div class="item">
<div class="item">
<div class="item">
<div class="item">
<div class="item">
<div class="item">
</div>
</div>
使用 jQuery
