<html lang="en">

</head>
<body onload="f1()">
<img id="img1" src=""alt="" width="200px">
<script>
let arr=new Array();
function image()
{
let img2=document.getElementById("img1");
x=0;
arr[x]="C:\Users\SUDARSHAN\Desktop\html_UI\images\1200px-Heart_corazon.svg.png"
img2.src=arr[x];
x=1;
arr[x]="C:\Users\SUDARSHAN\Desktop\html_UI\images\alex-haney-AGqzy-Uj3s4-unsplash.jpg"
img2.src=arr[x];
x=2;
arr[x]="C:\Users\SUDARSHAN\Desktop\html_UI\images\mitchell-luo-jz4ca36oJ_M-unsplash.jpg"
img2.src=arr[x];
x=0;

window.setInterval(image,4000);
}
</script>
</body>
</html>
这些图像的名称为 1.jpg、2.jpg 和 3.jpg,并且与 test.html 和 test.js 文件位于同一文件夹中。 你可以以秒为单位切换超时。

"use strict";
const imageArray = ["1.jpg", "2.jpg", "3.jpg"];
const imageSwitcher = document.getElementById("imageSwitcher");
let timeout = 4;
let i = 0;
setInterval(() => {
imageSwitcher.src=imageArray[i];
console.log(i);
i++;
if (i >= imageArray.length) {
i = 0;
}
}, timeout * 1000);
您必须增加指针并像下面的代码一样重置它。
<script>
var pointer = 0;
var imageArray = [
"C:\Users\SUDARSHAN\Desktop\html_UI\images\1200px-Heart_corazon.svg.png",
"C:\Users\SUDARSHAN\Desktop\html_UI\images\alex-haney-AGqzy-Uj3s4-unsplash.jpg",
"C:\Users\SUDARSHAN\Desktop\html_UI\images\mitchell-luo-jz4ca36oJ_M-unsplash.jpg"
];
function image()
{
let img2 = document.getElementById("img1");
img2.src = imageArray[pointer];
pointer++;
// reset the pointer if hit the max
if (pointer == imageArray.length-1){
pointer = 0;
}
}
function f1()
{
window.setInterval(image,4000);
}
</script>
