Как добавить функцию очистки input с помощью JS?

Question

Есть готовая форма в стиле Material Design

Пытаюсь добавить кнопки сброса к инпутам в виде крестиков, появляющихся справа когда в поле есть значение.

Подскажите как добавить событие на кнопку (крестик), чтобы при нажатии на неё поле очищалось?

const setActive = (el, active) => {
  const formField = el.parentNode.parentNode;
  if (active) {
   formField.classList.add('form-field--is-active');
    el.value === '' ?
    formField.classList.remove('form-field--is-clear') :
    formField.classList.add('form-field--is-clear');
  } else {
    formField.classList.remove('form-field--is-clear');
    formField.classList.remove('form-field--is-active');
    el.value === '' ?
    formField.classList.remove('form-field--is-filled') :
    formField.classList.add('form-field--is-filled');
  }
};



[].forEach.call(
document.querySelectorAll('.form-field__input, .form-field__textarea'),
el => {
  el.onblur = () => {
    setActive(el, false);
  };
  el.onfocus = () => {
    setActive(el, true);
  };

 el.onkeyup = () => {
    setActive(el, true);
  };

});

.form-field {

Answer 1

[].forEach.call(document.querySelectorAll('.form-field__clear'), (button) => {
  const field = button.parentNode.querySelector('.form-field__input');
  button.addEventListener('mousedown', (e) => {
    e.preventDefault();
    field.value = '';
  });
});

Answer 2

Получился такой код, все вроде как работает как и хотелось, если есть ошибки или можно ка то оптимизировать, подскажите пожалуйста!

https://codepen.io/mx928/pen/JjbBYMV

const setActive = (el, active) => {
  const formField = el.parentNode.parentNode;
  if (active) {
   formField.classList.add('form-field--is-active');
    el.value === '' ?
    formField.classList.remove('form-field--is-clear') :
    formField.classList.add('form-field--is-clear');
  } else {
    formField.classList.remove('form-field--is-clear');
    formField.classList.remove('form-field--is-active');
    el.value === '' ?
    formField.classList.remove('form-field--is-filled') :
    formField.classList.add('form-field--is-filled');
  }
};

[].forEach.call(
document.querySelectorAll('.form-field__input, .form-field__textarea'),
  
el => {
  if (el.value) {
    setActive(el, false);
   }
  el.onblur = () => {
    setActive(el, false);
  };
  el.onfocus = () => {
    setActive(el, true);
  };
 el.onkeyup = () => {
    setActive(el, true);
  };

});

[].forEach.call(
document.querySelectorAll('.form-field__clear'), 
(button) => {
  const field = button.parentNode.parentNode.querySelector('.form-field__input, .form-field__textarea');
  button.addEventListener('mousedown', (e) => {
    e.preventDefault();
    field.value = '';
    field.parentNode.parentNode.classList.remove('form-field--is-clear');
  });
});
