如果父级 <a> 具有特定类，如何使用 JavaScript 将 <span> 标签的文本用 <div> 括起来
我有以下代码 我有以下代码 <div class="team-grid"> <div class="cssgrid-wrapper"> <div class="cssgrid-container"> <div class="tmb"> <div class="t-inside "> <div class="t-entry-text"> <div class="t-entry-text-tc"> <div class="t-entry"> <p class="t-entry-meta"> <span class="t-entry-category t-entry-tax"> <a href="#">Category one</a> </span> </p> </div> </div> </div> </div> </div> </div> <div class="tmb"> <div class="t-inside "> <div class="t-entry-text"> <div class="t-entry-text-tc"> <div class="t-entry"> <p class="t-entry-meta"> <span class="t-entry-category t-entry-tax"> <a href="#">Category two</a> </span> </p> </div> </div> </div> </div> </div> </div> </div> 并且我想使用javascript将每个A标签的文本包含在具有“hide”类的SPAN中，如果a标签具有具有“team-grid”类的祖父母DIV和具有“t-entry”类的父SPAN -类别'。 所以在上面的例子中结果将是 <div class="team-grid"> <div class="cssgrid-wrapper"> <div class="cssgrid-container"> <div class="tmb"> <div class="t-inside "> <div class="t-entry-text"> <div class="t-entry-text-tc"> <div class="t-entry"> <p class="t-entry-meta"> <span class="t-entry-category t-entry-tax"> <a href="#"><span class="hide">Category one</span></a> </span> </p> </div> </div> </div> </div> </div> </div> <div class="tmb"> <div class="t-inside "> <div class="t-entry-text"> <div class="t-entry-text-tc"> <div class="t-entry"> <p class="t-entry-meta"> <span class="t-entry-category t-entry-tax"> <a href="#"><span class="hide">Category two</span></a> </span> </p> </div> </div> </div> </div> </div> </div> </div> 如有任何帮助，我们将不胜感激。 document.querySelectorAll('.team-grid .t-entry-category > a').forEach(a => { a.innerHTML = `<span class="hide">${a.textContent}</span>`; });
