如何将工具提示添加到格式字段

input[title] {
  position: relative;
}

input[title]:hover::after {
  content: attr(title);
  position: absolute;
  top: 100%;
  left: 0;
  background-color: #333;
  color: #fff;
  padding: 5px;
  border-radius: 5px;
}

const elements = document.querySelectorAll('input[title]');

elements.forEach(element => {
  element.addEventListener('mouseover', () => {
    const tooltip = document.createElement('div');
    tooltip.classList.add('tooltip');
    tooltip.textContent = element.getAttribute('title');
    document.body.appendChild(tooltip);
  });

  element.addEventListener('mouseout', () => {
    const tooltip = document.querySelector('.tooltip');
    if (tooltip) {
      tooltip.remove();
    }
  });
});
