Dom-closest

Utility for finding the closest parent of the current element (or the current element itself) which matches the selector.

Example

HTML

<div id="test-block-a" class="test-class test-class-a">
 	<div id="test-block-b" class="test-class-b" >
		<div id="test-block-c" class="test-class-c"></div>
	</div>
</div>;

JS

var assert = require( 'assert' );
var closest = require( '@cfpb/dom-closest' ).closest;
var testBlockA = document.getElementById( 'test-block-a' );
var testBlockB = document.getElementById( 'test-block-b' );
var element = domClosest( testBlockB, 'div' );

assert( element === testBlockB, true );
element = domClosest( testBlockB, '.test-class' );
assert( element === testBlockA );
