Node.nextSibling
The Node.nextSibling
read-only
property returns the node immediately following the specified one in their
parent's childNodes
, or returns null
if the specified node is the last child in the parent element.
Syntax
nextNode = node.nextSibling
Notes
Gecko-based browsers insert text nodes into a document to represent whitespace in
the source markup. Therefore a node obtained, for example, using Node.firstChild
or Node.previousSibling
may refer to a whitespace text node rather than the actual element the author
intended to get.
See Whitespace in the DOM and W3C DOM 3 FAQ: Why are some Text nodes empty? for more information.
Element.nextElementSibling
may be used to obtain the next element
skipping any whitespace nodes, other between-element text, or comments.
Example
<div id="div-1">Here is div-1</div>
<div id="div-2">Here is div-2</div>
<script>
var el = document.getElementById('div-1').nextSibling,
i = 1;
console.group('Siblings of div-1:');
while (el) {
console.log(i, '. ', el.nodeName);
el = el.nextSibling;
i++;
}
console.groupEnd();
</script>
/**************************************************
The console displays the following:
Siblings of div-1
1. #text
2. DIV
3. #text
4. SCRIPT
**************************************************/
In the above example, #text
nodes are inserted in the DOM where whitespace
occurs between tags (i.e. after the closing tag of an element and before the opening
tag of the next).
The possible inclusion of text nodes must be allowed for when traversing the DOM using
nextSibling
. See the resources in the Notes section.
