The ParentNode.lastElementChild
read-only property returns the object's last child Element
or null
if there are no child elements.
Note: This property was initially defined in the ElementTraversal
pure interface. As this interface contained two distinct set of properties, one aimed at Node
that have children, one at those that are children, they have been moved into two separate pure interfaces, ParentNode
and ChildNode
. In this case, lastElementChild
moved to ParentNode
. This is a fairly technical change that shouldn't affect compatibility.
Syntax
const element = node.lastElementChild
Example
<ul id="foo">
<li>First (1)</li>
<li>Second (2)</li>
<li>Third (3)</li>
</ul>
<script>
const foo = document.getElementById('foo');
console.log(foo.lastElementChild.textContent); // logs: Third (3)
</script>
Polyfill
The code below adds support of lastElementChild()
to Document
and DocumentFragment
in Internet Explorer and Safari.
// Overwrites native 'lastElementChild' prototype.
// Returns array instead of HTMLCollection.
;(function(constructor) {
if(constructor &&
constructor.prototype &&
constructor.prototype.lastElementChild == null) {
Object.defineProperty(constructor.prototype, 'lastElementChild', {
get: function() {
var node, nodes = this.childNodes, i = nodes.length - 1;
while(node = nodes[i--]) {
if(node.nodeType === 1) {
return node;
}
}
return null;
}
});
}
})(window.Node || window.Element);
