I try to initiate an event after another script:

My script try to 'alert button' on click button

document.addEventListener('click', function (e) {
    
    if(document.querySelectorAll("button")===e.target) {
alert('button');
    }
 
}, false);

exemple on the page button called "Verset Aléatoire" nothing happens

with your help i try this

var i,dots;
dots =  document.getElementsByClassName('button');
document.addEventListener('click', function (e) {
    for (i=0; i<dots.length; i  ){
    if(document.querySelectorAll("button")[i]===e.target) {
alert('button');
    }
 }
}, false);

nothings happens

You're not selecting the exact element what you need is to use an id for your button and then use a selector like document.getElementById('id')

As explained in the docs, querySelectorAll returns a NodeList so you cannot check for equivalence with e.target. If you must use this function you could try iterating over the NodeList instead.
