如何为 static HTML 网页上的脚本 src 字符串添加 Unix 时间戳和 Z686155AF75A60ADDF6EZD9？
[英]How do I add a Unix timestamp for a script src string on a static HTML webpage with JavaScript?
问题描述
I've come up with this, but it doesn't work:
我想出了这个，但它不起作用：
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body>
<script src="/test.php?nocache=" + Date.now() + "></script>
</body>
</html>
It has to be part of the src string.它必须是src字符串的一部分。 I believe I could do <script> console.log(Date.now()); </script>我相信我可以做到<script> console.log(Date.now()); </script> <script> console.log(Date.now()); </script> if all I wanted to do was to output the Unix timestamp in the browser console, but that's not what I'm trying to do. <script> console.log(Date.now()); </script>如果我只想在浏览器控制台中输入 output Unix 时间戳，但这不是我想要做的。 I'm trying to prevent the /test.php (which handles logging of page loads) from being cached by browsers, and since the page itself is not being served dynamically, I have to do it client-side.我试图防止浏览器缓存/test.php （处理页面加载日志），并且由于页面本身不是动态提供的，因此我必须在客户端进行。

You can not execute js in HTML attribute.您不能在 HTML 属性中执行 js。 But you could do like this但你可以这样做
<script>
const script=document.createElement('script');
script.src='/test.php?nocache=' + Date.now();
document.head.appendChild(script);
</script>

I suggest you load your script after the page has loaded.我建议您在页面加载后加载脚本。 This way you can dynamically set your script's src attribute:这样您就可以动态设置脚本的src属性：
var script = document.createElement("script");
script.setAttribute("src","/test.php?nocache=" + Date.now());
document.body.appendChild(script);
