[removed] How to get parent element by selector?

Answer 1

Here's a recursive solution:

function closest(el, selector, stopSelector) {
  if(!el || !el.parentElement) return null
  else if(stopSelector && el.parentElement.matches(stopSelector)) return null
  else if(el.parentElement.matches(selector)) return el.parentElement
  else return closest(el.parentElement, selector, stopSelector)
}
