domhelpers

DOMhelpers is a (very) small collection of some handy utility functions which help you query the DOM.

getClosest(element, selector)

Get the closest element from element which matches selector. This includes the element itself.

<div class="el1">
  <div class="el2"></div>
</div>

var el2 = document.querySelector('.el2');
console.log(getClosest(el2, '.el1')); // div.el1
console.log(getClosest(el2, '.el2')); // div.el2

getParent(element, selector)

Get the closest element from element which matches selector. This does NOT include the element itself, instead it searches from the element's parentNode.

<div class="el1">
  <div class="el2"></div>
</div>

var el2 = document.querySelector('.el2');
console.log(getClosest(el2, '.el1')); // div.el1
console.log(getClosest(el2, '.el2')); // undefined

getParents(element, selector)

Get all parents from element which match selector. This function always returns an array.

<div class="el1">
  <div class="el1">
    <div class="el2"></div>
  </div>
</div>

var el2 = document.querySelector('.el2');
console.log(getClosest(el2, '.el1')); // [div.el1, div.el1]
console.log(getClosest(el2, '.el2')); // []
