我是 html 和 Flask 的新手，非常感谢任何帮助。
我有一个 html 代码，其中显示两个定期更新的图像。每次再次保存/覆盖这些图像时，我都需要刷新它们。这是html代码：
<!DOCTYPE html>
<html lang="en">
<head>
<!-- include jQuery - better done in the head -->
<script src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Stack of Images</title>
<meta http-equiv="refresh" content="2">
</head>
<body>
<img src="static/X.jpg" alt="Image 1" id = "img1" width="960" height="540">
<img src="static/X_display.jpg" alt="Image 2" id = "img2" width="960" height="540">
</body>
</html>不要使用重新加载，只需使用缓存破坏器和javascript
window.addEventListener('load',() => {
const imgs = ["img1","img2"].map(img => document.getElementById(img));
setInterval(() => {
const rnd = new Date().getTime();
imgs.forEach(img => img.src = `${img.src.split('?')[0]}?${rnd}`);
},2000)
}); <img src="static/X.jpg" alt="Image 1" id="img1" width="960" height="540">
<img src="static/X_display.jpg" alt="Image 2" id="img2" width="960" height="540">
