List dataLayer events as they fire
Prints each event name in the console the moment it reaches the dataLayer, so you can follow the event flow live.
Code to copy
try {
window.dataLayer = window.dataLayer || [];
var dl = window.dataLayer;
if (!dl.__jzEvents) {
var origPush = dl.push.bind(dl);
dl.push = function () {
try {
for (var i = 0; i < arguments.length; i++) {
var a = arguments[i];
var name = (a && (a.event || a[0])) || '(no event name)';
console.log('%c→ ' + name, 'color:#34A853;font-weight:700');
}
} catch (e) {}
return origPush.apply(dl, arguments);
};
dl.__jzEvents = true;
console.log('Live dataLayer event listing enabled.');
}
} catch (e) {
console.warn('GTM event listing failed:', e);
