我正在尝试制作下面给出的简单轮播JavaScript代码:
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, 6000);
}
这是HTML:
<div class="slideshow-container">
<div class="mySlides fade">
<div class="numbertext">1 / 2</div>
<img src="images/i1.jpg" style="width:100%">
<div class="text">Caption One</div>
</div>
<div class="mySlides fade">
<div class="numbertext">2 / 2</div>
<img src="images/i2.png" style="width:100%">
<div class="text">Caption Two</div>
</div>
</div>
我想在该图像滑块上显示用户上传的任何随机图像,但我注意到图像的高度和宽度会影响周围的其他html元素,并建议是否有更有效的方法来执行此操作。
