Element: lastElementChild プロパティ
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2015年7月.
Element.lastElementChild は読み取り専用のプロパティで、要素の最後の子を Element で返します。子要素がない場合は null を返します。
Element.lastElementChild は要素ノードのみを含みます。
テキストやコメントノードなど、要素以外のノードを含むすべての子ノードを取得するには、 Node.lastChild を使用してください。
値
Element オブジェクト、または null です。
例
html
<ul id="list">
<li>First (1)</li>
<li>Second (2)</li>
<li>Third (3)</li>
</ul>
<script>
const list = document.getElementById("list");
console.log(list.lastElementChild.textContent);
// logs "Third (3)"
</script>
