【问题描述】：

我有一个输出电子商务类别列表的 cms - 我试图隐藏前 4 个之后的所有列表项，然后添加一个链接以查看更多指向类别页面的链接。类别页面链接与我要添加到的列表位于同一父（或祖父？？）元素中。我有这个工作来添加链接，但它似乎将第一个链接放在所有 div 中。请看下面的代码：

$(".ecommMenuItem ul").append('<li><a href="#" class="view-all">View All</a></li>');

  $(".ecommMenuItems").each(function(){
    var divtext = $(".category-link", this).attr("href");
    $(".view-all", this).attr("href", divtext); 
  });

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<div class="ecommMenuItems">
	<div class="ecommMenuItem">
		<a class="category-link" href="/subgroup/bga-stencil/" title="BGA Stencil"><i class="category-icon"><img src="/ebuyerfix-com/_img/img/placeholder.jpg"></i><span class="category-title" style="height: 15px;">BGA Stencil</span></a>
		<ul>
			<li><a id="catId8468" href="/_shop/ur-selected-stencil/" title="UR Selected Stencil">UR Selected Stencil</a></li>
			<li><a id="catId8469" href="/_shop/laser-tech-stencil/" title="Laser Tech Stencil">Laser Tech Stencil</a></li>

		</ul>
	</div>

<div class="ecommMenuItem">
	<a class="category-link" href="/subgroup/hand-tools/" title="Hand Tools"><i class="category-icon"><img src="/ebuyerfix-com/_img/img/placeholder.jpg"></i><span class="category-title" style="height: 15px;">Hand Tools</span></a>

</div>

所以我想要实现的是将每个“.ecommMenuItem”上的“.category-link”中的href添加到同一个.ecommMenuItem中的“.view-all”href中。

非常感谢任何帮助。

【解决方案1】：

您正在循环遍历每个菜单的分组上方的.ecommMenuItems 元素。相反，您需要遍历 .ecommMenuItem：

$(".ecommMenuItem").each(...

另外请注意，通过在 CSS 中使用 :nth-child()，可以避免在中间 li 元素上设置内联 display: none。试试这个：

$(".ecommMenuItem ul").append('<li><a href="#" class="view-all">View All</a></li>');

$(".ecommMenuItem").each(function() {
  var divtext = $(".category-link", this).attr("href");
  $(".view-all", this).attr("href", divtext);
});

.ecommMenuItem li:nth-child(n+5):not(:last-child) {
  display: none;
}
