How to apply a function to all divs with id/class?

Question

JavaScript

It is necessary that when clicking, moving and releasing on the div, different functions occurred.
There are a lot of divs with the same id/class and you need to have the same functions for each.
tried but addEventListener only works with 1 div

Answer 1

function handler(e) {
    // ...
}

document.addEventListener('event-type', event => {
    if (event.target.classList.contains('my-class')) {
        handler(event);
    }
});
