Hey Alex, you can use a script like this to get a session ID, just set it to a session-scoped custom dimension. You can see more about this in this article.

function() { return new Date().getTime() + '.' + Math.random().toString(36).substring(5);}

I think you just need to substitute in the right selectors, something like this should work:
function() {
var e = {{Click Element}};
var closestID = e.closest('img');
return closestID.src;
}

Is it posible to get picture link instead the class.
In your example I need to grab "coffe & café" picture when it clicked ?

I need to grab it to use img link to push images in my data studio report.

Thanks 🙂

Allready used it, thanks!

Hey there, I'm glad you like the post! The following should work to get the class name:
function() {
var e = {{Click Element}};
var closestClass = e.closest('[class]');
return closestClass.className;
}

Great article! Very useful list.

Do you know how to get the parent class name? So like #1, but then with the class?

Thanks!

Hey, it's not a stupid question. Do you already have variables set up that contain transaction revenue and shipping? If so, your new custom JS variable would look like this (just edit the variable names to match the names you've used in your container):
function(){
return {{revenue}} - {{shipping}};
}
If you don't have revenue and shipping variables already set up, you can check this post for how to grab those values from an enhanced ecommerce data layer: Collect Enhanced Ecommerce Values into GTM Variables. If you're using standard ecommerce let me know as the syntax will be a bit different.
