使用jquery,从更大的兄弟组中提取每组相邻兄弟,匹配选择器
Using jquery, extract each group of adjacent siblings, matching selector, from a larger group of siblings
我有以下标记:
<div id="parent">
<div class="special child"></div>
<div class="child"></div>
<div class="child"></div>
<div class="child"></div>
<div class="special child"></div>
<div class="special child"></div>
<div class="special child"></div>
<div class="child"></div>
<div class="child"></div>
</div>
我需要做的是提取 div.special
的 2 个子集合(对于 2 组相邻的兄弟姐妹),然后用另一个父级包装每个组,最后是:
<div id="parent">
<div class="special_parent">
<div class="special child"></div>
</div>
<div class="child"></div>
<div class="child"></div>
<div class="child"></div>
<div class="special_parent">
<div class="special child"></div>
<div class="special child"></div>
<div class="special child"></div>
</div>
<div class="child"></div>
<div class="child"></div>
</div>
我可以先遍历同级元素并完成一些繁重的工作,但我确信应该有更优雅的方法。
使用each()
and nextUntil()
$('.special').each(function() {
if ($(this).parent().hasClass('special_parent')) return
$(this)
.nextUntil(':not(.special)')
.add(this)
.wrapAll('<div class="special_parent">')
})
.special_parent {
color: red;
}
