你也可以将幻灯片设置为自动播放，JavaScript 代码修改为如下：

JavaScript 代码：

[mycode3 type="js"]
var slideIndex = 0;
showSlides();

function showSlides() {
var i;
var slides = document.getElementsByClassName("mySlides");
for (i = 0; i < slides.length; i++) { slides[i].style.display = "none"; } slideIndex++; if (slideIndex> slides.length) {slideIndex = 1}
slides[slideIndex-1].style.display = "block";
setTimeout(showSlides, 2000); // 间隔两秒后修改图片
}
