I am trying to find the closest element with a specific tag name without jquery. When I click on a <th> I want to get access to the <tbody> for that table. Suggestions? I read about offset but didn't really understand it too much. Should I just use:
Assume th is already set to clicked th element
th.offsetParent.getElementsByTagName('tbody')[0]
Little (very) late to the party, but nonetheless. This should do the trick:
function closest(el, selector) {
var matchesFn;
// find vendor prefix
['matches','webkitMatchesSelector','mozMatchesSelector','msMatchesSelector','oMatchesSelector'].some(function(fn) {
if (typeof document.body[fn] == 'function') {
matchesFn = fn;
return true;
}
return false;
})
var parent;
// traverse parents
while (el) {
parent = el.parentElement;
if (parent && parent[matchesFn](selector)) {
return parent;
}
el = parent;
}
return null;
}
