Detecting if a button has been pressed on the whole document

I want to detect if a button has been pressed on a document. That means I don’t want to put in document.getElementById("ID").onclick for each button. In other words, i want to detect if ANY button has been pressed on the document. If a button is pressed, get that button object, get it’s textContent and that’s all there is to it.

Answer

Have you tried this?

let buttons = document.querySelectorAll(".button");

buttons.forEach(btn=>{
    btn.addEventListener("click",function(e){
    btn.innerText = "CLICKED BUTTON"
    });
});

<button class="button">1</button>
<button class="button">2</button>
<button class="button">3</button>
<button class="button">4</button>
