--- title: Get parents until element matches selector tags: browser author: chalarangelo cover: colorful-plastic firstSeen: 2021-01-05T22:47:21+02:00 lastUpdated: 2021-01-06T13:04:18+02:00 --- Finds all the ancestors of an element up until the element matched by the specified selector. - Use `Node.parentNode` and a `while` loop to move up the ancestor tree of the element. - Use `Array.prototype.unshift()` to add each new ancestor to the start of the array. - Use `Element.matches()` to check if the current element matches the specified `selector`. ```js const getParentsUntil = (el, selector) => { let parents = [], _el = el.parentNode; while (_el && typeof _el.matches === 'function') { parents.unshift(_el); if (_el.matches(selector)) return parents; else _el = _el.parentNode; } return []; }; ``` ```js getParentsUntil(document.querySelector('#home-link'), 'header'); // [header, nav, ul, li] ```
