HTML DOM children Property

The DOM children property is used to return an HTML collection of all the child elements of the specified element. The elements in the collection can be accessed by index numbers. It differs from childNodes as childNodes contain all nodes (i.e. it includes text and comment nodes as well) but on the other hand, children contain only element nodes. This is a read-only property.

Syntax:

element.children

Return Value: It returns a collection of element nodes that can be accessed by indexing.

Example 1: This example returns the number of list items.

HTML

<!DOCTYPE html>
<html>
<head>
    <title>
        HTML DOM children Property
    </title>
 
    <!-- Script to count children of parent attribute -->
    <script>
        function Geeks() {
            let count =
                document.getElementById("parent").children.length;
                document.getElementById("p").innerHTML =
                    "No of Children: " + count;
        }
    </script>
</head>
 
<body>
    <h1>GeeksforGeeks</h1>
    <h2>
        DOM children Property
    </h2>
    <p>Searching Algorithms</p>
    <ul id="parent">
        <li>Merge sort</li>
        <li>Quick sort</li>
    </ul>
    <button onclick="Geeks()">
        Click Here!
    </button>
    <p id="p"></p>
</body>
</html>
