try this example:

var el = event.target.parentElement;
var v = getAttribute(el, "data-attribute");

function getAttribute (dom, attr) {
            if (dom.getAttribute !== undefined) {
                return dom.getAttribute(attr);
            } else if (dom[attr] !== undefined) {
                return dom[attr];
            } else if (dom.getAttributeNode !== undefined) {
                return dom.getAttributeNode(attr);
            }else{
                  return null;
            }
        }

Output in the IE 11 browser:
