This option comes with its own disadvantages, though, since it brings you back to long wait times and lack of flexibility.

The target event property returns the element that triggered the event. customEmoji); // fuu // Pretty cool right! The getAttribute() method returns the value of the attribute with the specified name, of an element.

In this post I’ll discuss another approach to event tracking: custom data attributes. Using this attribute to store small chunks of arbitrary data, developers are able to avoid unneccessary AJAX calls and enhance user experience. You would add this into a custom JavaScript variable in GTM, and use this Variable in place of the dataset.tilePosition data layer Variable above. It looks like React does this so that it works across more browsers. Custom data attributes get added to the HTML just like regular IDs and classes, and can therefore leverage all the benefits of GTM’s built-in triggers. That means in the above example to get the data-id using data() method you can use the statement like $(this).data("id"). 4) Get selected
