    « DOM Reference « ParentNode

    The ParentNode.firstElementChild read-only property returns the object's first child Element, or null if there are no child elements.

    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, firstElementChild moved to ParentNode. This is a fairly technical change that shouldn't affect compatibility.


    var childNode = elementNodeReference.firstElementChild; 


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

    In this example, the alert shows 'span', which is the tag name of the first child node of the paragraph element.


    Specification Status Comment
    DOM Living Standard Splitted the ElementTraversal interface in ChildNode and ParentNode. This method is now defined on the latter.
    The Document and DocumentFragment implemented the new interfaces.
    Element Traversal Specification Recommendation Added its initial definition to the ElementTraversal pure interface and use it on Element.
