HTML | DOM children Property
  • Last Updated : 25 Jul, 2019

The DOM children property is used to return HTMLcollection 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 contains all nodes (i.e. it includes text and comment nodes as well) but on the other hand, children contains only element nodes. This is a read-only property.

Syntax:

element.children

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

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

    <!-- Script to count children of parent attribute -->
    <script>
        function Geeks() {
            var count =
                document.getElementById("parent").children.length;
  
            document.getElementById("p").innerHTML = 
                  "No of Children: " + count;
        }
    </script>
