1. Use the native closest() method

const result = ele.closest(selector);
Note that the closest method isn't supported in IE.

2. Traverse up until find the matching element

const matches = function (ele, selector) {
return (
ele.matches ||
ele.matchesSelector ||
ele.msMatchesSelector ||
ele.mozMatchesSelector ||
ele.webkitMatchesSelector ||
ele.oMatchesSelector
).call(ele, selector);
};

// Find the closest element to `ele` and matches the `selector`
const closest = function (ele, selector) {
let e = ele;
while (e) {
if (matches(e, selector)) {
break;
}
e = e.parentNode;
}
return e;
};
