Доступное только для чтения свойство ParentNode.firstElementChild возвращает первый дочерний элемент объекта ({{domxref("Element")}}) или null если дочерних элементов нет.

- -
-

This property was initially defined in the {{domxref("ElementTraversal")}} pure interface. As this interface contained two distinct set of properties, one aimed at {{domxref("Node")}} that have children, one at those that are children, they have been moved into two separate pure interfaces, {{domxref("ParentNode")}} and {{domxref("ChildNode")}}. In this case, firstElementChild moved to {{domxref("ParentNode")}}. This is a fairly technical change that shouldn't affect compatibility.

Синтаксис

- -
var childNode = elementNodeReference.firstElementChild;
-
- -

Пример

- -
<p id="para-01">
-  <span>First span</span>
-</p>
-
-<script type="text/javascript">
-  var p01 = document.getElementById('para-01');
-  alert(p01.firstElementChild.nodeName)
-</script>
- -

В этом примере alert показывает 'span', что является именем тега первого дочернего узла элемента p.

Polyfill для Internet Explorer 8

- -

Это свойство не поддерживается браузером Internet Explorer вплоть до 9 версии, поэтому следующий сниппет может быть использован для добавления поддержки IE8:

- -
// Source: https://github.com/Alhadis/Snippets/blob/master/js/polyfills/IE8-child-elements.js
-if(!("firstElementChild" in document.documentElement)){
-    Object.defineProperty(Element.prototype, "firstElementChild", {
-        get: function(){
-            for(var nodes = this.children, n, i = 0, l = nodes.length; i < l; ++i)
-                if(n = nodes[i], 1 === n.nodeType) return n;
-            return null;
-        }
-    });
