Created September 14, 2020 09:08 — forked from sahava/add-missing-datalayer-event.js

This piece of code adds a default 'event' key-value to each dataLayer.push() that hasn't got one.

	(function() {
	var oldPush = window.dataLayer.push;
	window.dataLayer.push = function() {
	var states = [].slice.call(arguments, 0);
	states.forEach(function(s) {
	if (!s.hasOwnProperty('event')) {
	s.event = 'default';
	}
	});
	return oldPush.apply(window.dataLayer, states);
