Access buttons of a div as an array

This is a problem I was having:

I am trying to access the button inside of the div and make each of them log its own text content on click. But all of them display all of the text content. And it has to be in vanilla JavaScript.

const array = document.querySelectorAll(".div");
array.forEach(button => {
    button.addEventListener('click', function (){
        console.log(this.textContent)
    })
});
 <div class=div>
  <button>Button 1</button>
  <button>Button 2</button>
  <button>Button 3</button>
  <button>Button 4</button>
</div>

I Used a for loop and a for each loop. None worked.

Solution

  • You can access the event.target to get the context of the click.

    document.querySelectorAll('.my-div').forEach(function(button) {
  button.addEventListener('click', function(event) {
    console.log(event.target.textContent)
  })
});
    <div class="my-div">
  <button>Button 1</button>
  <button>Button 2</button>
  <button>Button 3</button>
  <button>Button 4</button>
</div>

    Even better, you could delegate the event and reuse the listener for any button that matches the selector.

    document.querySelector('.my-div').addEventListener('click', function(event) {
  if (event.target.matches('button')) {
    handleClick(event);
  }
});

function handleClick(event) {
  console.log(event.target.textContent);
}
    <div class="my-div">
  <button>Button 1</button>
  <button>Button 2</button>
  <button>Button 3</button>
  <button>Button 4</button>
</div>
