<div class="container">
<div class="box" onmouseover="showTooltip('这是一个提示信息！')" onmouseout="hideTooltip()"><p>点击我查看提示</p></div>
<div id="tooltip"></div>
</div>
<script>
function showTooltip(text) {
var tooltip = document.getElementById("tooltip");
tooltip.textContent = text;
tooltip.style.visibility = "visible";
}
function hideTooltip() {
var tooltip = document.getElementById("tooltip");
tooltip.style.visibility = "hidden";
}

function showSlide(index) {
slides.forEach((slide) => slide.style.display = 'none');
slides[index].style.display = 'block';
dots.forEach((dot) => dot.classList.remove('active'));
dots[index].classList.add('active');
}
setInterval(() => {
currentSlide = (currentSlide + 1) % slides.length;
showSlide(currentSlide);
}, 3000);
dots.forEach((dot, index) => {
dot.addEventListener('click', () => {
