如何遍历 li ，但要删除某些 li 标记内的 span 标记内容？
答案 0 :(得分：1)
无需遍历所有'.ingredients-list li'元素。
您可以使用$('.ingredients-list li').find('span').remove();删除所有span元素。
代码：
$('.ingredients-list li').find('span').remove();<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="ingredients-list">
<div class="ingredients-list__content">

答案 1 :(得分：1)
您可以检查 nodeType 属性，以仅返回每个 li 元素中的文本：
$('.ingredients-list li').each(function(i, elm) {
var text = $(this).contents().filter(function() {
return this.nodeType == 3 || $(this).is('a'); // text node or anchor
}).text().trim();
console.log(text);
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
