TrackEvent get parameters from selected element

I want to track clicks on a few elements using a certain CSS selector. Right now, I'm adding a click listener using the JavaScript methods and using a for loop to add the trackEvent call to get parameters from the "my-custom-name" attribute in each selected element. Instead of using the document.querySelectorAll function to get parameters from the "my-custom-name" element attribute, is there a way to get those parameters and send them with the trackEvent call?
