The
closest()
method traverses the Element
and its parents (heading toward the document root) until it finds a node that matches the provided selector string. Will return itself or the matching ancestor. If no such element exists, it returns null
.Syntax
var closestElement = targetElement.closest(selectors);
Parameters
selectors
is aDOMString
containing a selector list.
ex:p:hover, .toto + q
Return value
closestElement
is theElement
which is the closest ancestor of the selected element. It may benull
.
Exceptions
SyntaxError
is thrown if theselectors
is not a valid selector list string.
Example
HTML
<article> <div id="div-01">Here is div-01 <div id="div-02">Here is div-02 <div id="div-03">Here is div-03</div> </div> </div> </article>
JavaScript
var el = document.getElementById('div-03'); var r1 = el.closest("#div-02"); // returns the element with the id=div-02 var r2 = el.closest("div div"); // returns the closest ancestor which is a div in div, here it is the div-03 itself var r3 = el.closest("article > div"); // returns the closest ancestor which is a div and has a parent article, here it is the div-01 var r4 = el.closest(":not(div)"); // returns the closest ancestor which is not a div, here it is the outmost article
Polyfill
For browsers that do not support Element.closest()
, but carry support for element.matches()
(or a prefixed equivalent, meaning IE9+), a polyfill exists:
if (!Element.prototype.matches) { Element.prototype.matches = Element.prototype.msMatchesSelector || Element.prototype.webkitMatchesSelector; } if (!Element.prototype.closest) { Element.prototype.closest = function(s) { var el = this; do { if (Element.prototype.matches.call(el, s)) return el; el = el.parentElement || el.parentNode; } while (el !== null && el.nodeType === 1); return null; }; }
However, if you really do require IE 8 support, then the following polyfill will do the job very slowly, but eventually. However, it will only support CSS 2.1 selectors in IE 8, and it can cause severe lag spikes in production websites.
if (window.Element && !Element.prototype.closest) { Element.prototype.closest = function(s) { var matches = (this.document || this.ownerDocument).querySelectorAll(s), i, el = this; do { i = matches.length; while (--i >= 0 && matches.item(i) !== el) {}; } while ((i < 0) && (el = el.parentElement)); return el; }; }

Compatibility notes

document.createElement(tagName).closest(tagName)
will returnnull
if the element is not first connected (directly or indirectly) to the context object, for example theDocument
object in the case of the normal DOM.
