问Js mouseClick事件似乎在错误的组件上触发

EN

function initRipple() {

  //qck define
  let rcont;

  rcont = Array.from(document.getElementsByClassName('ripple'));

  rcont.forEach(function(el) {
    el.addEventListener('click', function(evt) {
      ripple(el, evt);
    });
  });

}

function ripple(el, evt) {

  // qck def
  let cir, x, y;

  // assign values
  cir = document.createElement('div');
  x = evt.clientX;
  y = evt.clientY;

  // modify circle attributes / position
  cir.classList.add('ripple-bubble');
  cir.style.left = `${ x - 12 }px`;
  cir.style.top = `${ y - 12 }px`;

  cir.addEventListener('animationend', function() {
    let oldChild = el.removeChild(cir);
  });

  el.appendChild(cir);
