Functions for geting the parent element in Javascript
var getParentNode = function(elem, level) {
level = level || 1;
for (var i = 0; i < level; i++) {
if (elem != null) {
elem = elem.parentNode;
}
}
return elem;
}
// 2nd param optional, bubbles up to document
getParents( document.getElementById('me') );
// get all parents starting from -me- up to ID -outerParent-
getParents( document.getElementById('me'), document.getElementById('outerParent') );
function getParents(el, parentSelector /* optional */) {
// If no parentSelector defined will bubble up all the way to *document*
if (parentSelector === undefined) {
parentSelector = document;
}
var parents = [];
var p = el.parentNode;
while (p !== parentSelector) {
var o = p;
parents.push(o);
p = o.parentNode;
}
parents.push(parentSelector); // Push that parentSelector you wanted to stop at
return parents;
}
