Will M Smith Google Tag Manager and Lightning Community and Components
I've managed to import the Google Tag Manager code into the <head> using the lightning community settings tab. This loads perfectly fine and I can see the 'preview' window for google tag manager.
However, when I try to access the 'dataLayer' or 'window.dataLayer' object in a lightning component controller, it appears as undefined. I understand this is due to the SecureWindow that has been implemented.
For example:
Is there still no way at all I can access the dataLayer using lightning communities and components? If not, this unfortunately makes it a nightmare for my customer to track in-depth interactions on their community... I'm surprised Salesforce have overlooked this...
<!-- Google Tag Manager -->
<script>(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-XXXXXXX');</script>
<!-- End Google Tag Manager -->
However, when I try to access the 'dataLayer' or 'window.dataLayer' object in a lightning component controller, it appears as undefined. I understand this is due to the SecureWindow that has been implemented.
For example:
addCourseToCart : function(component, event, helper) {
dataLayer.push({
'event': 'addToCart',
'ecommerce': {
'currencyCode': 'EUR',
'add': { // 'add' actionFieldObject measures.
'products': [{ // adding a product to a shopping cart.
'name': 'Triblend Android T-Shirt',
'id': '12345',
'price': '15.25',
'brand': 'Google',
'category': 'Apparel',
'variant': 'Gray',
'quantity': 1
}]
}
}
});
},
