如何使用javaScript代码随机更改urls和图片？

// 定义URLs和图片链接数组
var urls = [
  "https://example.com/page1",
  "https://example.com/page2",
  "https://example.com/page3"
];

var images = [
  "https://example.com/image1.jpg",
  "https://example.com/image2.jpg",
  "https://example.com/image3.jpg"
];

// 随机生成索引
var randomIndex = Math.floor(Math.random() * urls.length);

// 更改URL
location.href = urls[randomIndex];

// 更改图片
var imgElement = document.getElementById("myImage"); // 假设有一个id为"myImage"的图片元素
imgElement.src = images[randomIndex];
