popupLink-alt.js

var elements = document.querySelectorAll('.socialshares a');
Array.prototype.forEach.call(elements, function(el, i){
  el.onclick = function(elaction) {
    elaction.preventDefault();
    window.open( el.attributes.href.value, '', 'width=600,height=300' );
  }
});

popupLink.js

document.addEventListener('DOMContentLoaded', function() {
	[].forEach.call(document.querySelectorAll('.puw'), function(el) {
		el.addEventListener('click', function(e) {
			if (e.target.nodeName.toLowerCase() == 'a') {
				e.preventDefault();
			}
			window.open( e.target.href, '', 'width=600,height=300' );
		});
	});
});

    var elements = document.querySelectorAll('.socialshares a');
    Array.prototype.forEach.call(elements, function(el, i){
      el.onclick = function(elaction) {
        elaction.preventDefault();
        window.open( el.attributes.href.value, '', 'width=600,height=300' );
