如何將自動幻燈片添加到 JavaScript 滑塊 10 秒？
[英]How to add automatic slideshow to the JavaScript slider for 10 seconds?
問題描述
我試圖添加 setTimeout(showSlides, 10000); 但它不起作用。 在不使頁面延遲的情況下進行自動幻燈片放映的最佳方法是什么？
var slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
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";
}
