Apologies for this kind of question, but I can't find an answer on You Might Not Need jQuery or anywhere else online and I'd really like to know:
There is no one function/property in the DOM API that equates to jQuery's
parents(). There is the
parentNode property, which is the parent element of the element on which you access it. To roughly match jQuery's
parents(), you can loop on it (e.g., get the
parentNode of the
parentNode, etc.) to find all the parents. As squint notes, on vaguely-modern browsers at each level you can use
matches to check if the parent matches a selector (to match jQuery's behavior with
parents() when you pass it a selector).
jQuery takes a set-based approach to DOM manipulation and traversal, whereas the DOM API takes a per-element/node approach.
