Dump dataLayer / gtag
Logs the contents of the dataLayer array to the console and reports whether the gtag function exists.
Code to copy
try {
const dl = window.dataLayer;
if (Array.isArray(dl)) {
console.log('JustZix: dataLayer has ' + dl.length + ' entries');
dl.forEach(function (entry, i) { console.log(i, entry); });
} else {
console.log('JustZix: no window.dataLayer array found');
}
if (typeof window.gtag === 'function') {
console.log('JustZix: window.gtag is present');
}
} catch (err) { console.error('JustZix dataLayer dump:', err); }How to use this example
