我可以用javascript创建自动幻灯片.但我不仅希望手动,而且需要按钮控制.
我添加了一些手动控制代码.然后幻灯片显示无法正常工作.这是自动幻灯片放映的代码.如何修改它以使用按钮.
var slideIndex = 0;
showSlides();
function showSlides() {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
slideIndex++;
if (slideIndex> slides.length) {slideIndex = 1}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
setTimeout(showSlides, 8000); // Change image every 8 seconds
}#slide{
width:96%;
}
* {
box-sizing: border-box
}
.mySlides …
