Question

不知道这是否可行.. 我想在每个第二个span-tag中添加一个li元素。我的HTML看起来像这样：

<span class="article_item"><img src="images/container_item.jpg" /><h2><a href="">Nokia Connecting N97</a></h2><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer eu mattis lectus.</p></span>

<span class="article_item"><img src="images/container_item.jpg" /><h2><a href="">Nokia Connecting N97</a></h2><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer eu mattis lectus.</p></span>

<span class="article_item"><img src="images/container_item.jpg" /><h2><a href="">Nokia Connecting N97</a></h2><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer eu mattis lectus.</p></span>

<span class="article_item"><img src="images/container_item.jpg" /><h2><a href="">Nokia Connecting N97</a></h2><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer eu mattis lectus.</p></span>

最后，它应该是这样的：

<li>
    <span class="article_item"><img src="images/container_item.jpg" /><h2><a href="">Nokia Connecting N97</a></h2><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer eu mattis lectus.</p></span>

    <span class="article_item"><img src="images/container_item.jpg" /><h2><a href="">Nokia Connecting N97</a></h2><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer eu mattis lectus.</p></span>
</li>
<li>  
    <span class="article_item"><img src="images/container_item.jpg" /><h2><a href="">Nokia Connecting N97</a></h2><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer eu mattis lectus.</p></span>
    <span class="article_item"><img src="images/container_item.jpg" /><h2><a href="">Nokia Connecting N97</a></h2><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer eu mattis lectus.</p></span>
</li>

任何想法？谢谢:)）

您可以在循环中使用.wrapAll()和.slice()，如下所示：

var spans = $("span.article_item");
for(var i = 0; i < spans.length; i+=2) {
  spans.slice(i, i+2).wrapAll("<li />");
}

You can test it out here，请务必在最后执行此类操作，因为<li>元素需要父级：

$("li").wrapAll("<ul />");

使用jQuery </span>在每秒<span>标记周围添加li元素
