我正在建立一个网站，其中在标题div我要添加幻灯片。我的代码拍摄并显示第一个图像，但滑块不起作用我将所有图像放在图像文件夹中.html文件是
<html>
<head>
<title>slideshow</title>
</head>
<body>
<img scr ="image/slider1.jpg" id = "img"/>
<script language="javascript" type="text/javascript" scr="slideshow.js"></script>
</body>
和我的.js文件就是这个
var myImage = doucoment.getElementById("img");
var ImageArray = ["slider1.jpg", "slider2.jpg", "slider3.jpg"];
ImageIndex = 0;
function changeImage() {
img.setAttribute("src", ImageArray[ImageIndex]);
ImageIndex++;
if (ImageIndex >= ImageArray.length){
ImageIndex = 0;
}
}
var ImageHandle = setInterval(changeImage, 3000);
答案 0 :(得分：0)
您的HTML和JavaScript中有拼写错误 ..
更改
scr至src
和
doucoment至document
以下是经过修改的代码段。
var myImage = document.getElementById("img");
// ^^^^^^^ typo here.
var ImageArray = ["https://www.google.com.pk/logos/doodles/2016/2016-doodle-fruit-games-day-8-5666133911797760.3-hp.gif", "http://reservations.life/css/images/bg-01.jpg"];
ImageIndex = 0;
function changeImage(){
img.setAttribute("src", ImageArray[ImageIndex]);
ImageIndex++;
if(ImageIndex >= ImageArray.length){
ImageIndex = 0;
}
}
var ImageHandle = setInterval(changeImage,3000);img{
width:400px;
height:200px;
}// ||| typo here.
<img src ="https://www.google.com.pk/logos/doodles/2016/2016-doodle-fruit-games-day-8-5666133911797760.3-hp.gif" id = "img"/>

var slides = document.querySelectorAll('#slides .slide');
var currentSlide = 0;
var slideInterval = setInterval(nextSlide,2000);
function nextSlide() {
slides[currentSlide].className = 'slide';
currentSlide = (currentSlide+1)%slides.length;
slides[currentSlide].className = 'slide showing';
}#slides {
position: relative;
height: 300px;
