Quick Tip
So you have this very fast AJaX page loader (InstantClick) on your website, but you want to use Google Tag Manager and track your pageview with Analytics etc; here’s how you reset Tag Manager and re-load it after your AJaX page is loaded;
InstantClick.on('change', function () {
jQuery('link[rel="canonical"]').attr('href', location.href);
ga = gaData = gaGlobal = gaplugins = google_tag_manager = dataLayer = undefined;
(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-ABCDEF78');
});
