如何最好地选择动态添加的脚本？我的代码（头）中有一个脚本与requirejs动态添加在一起。我想选择它，但不能。始终返回NULL
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Example</title>
<script>
document.addEventListener('DOMContentLoaded', function(){
let script = document.querySelector('[data-requiremodule="3.6.5/browser-polyfill"]');
console.log('DEBUG START');
console.log(script);
});
</script>
</head>
<body>
<h1>
Example
</h1>
<script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.js"></script>
<!-- Adding a script dynamically -->
<script>require.config({"waitSeconds":300,"baseUrl":"https:\/\/cdnjs.cloudflare.com\/ajax\/libs\/6to5\/","config":{"i18n":{"locale":"en"}}});require(["3.6.5/browser-polyfill"]);</script>
</body>
</html>编辑1：如果在问题中不清楚，我想获取正在头部动态创建的脚本（使用页面上的inspect元素，请参见）not require.js
我想选择：<script type="text/javascript" charset="utf-8" async="" data-requirecontext="_" data-requiremodule="3.6.5/browser-polyfill" src="https://cdnjs.cloudflare.com/ajax/libs/6to5/3.6.5/browser-polyfill.js"></script>
您的querySelector()调用正在寻找具有data-requiremodule...属性的元素，但是HTML中没有该属性。您可以改用src：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Example</title>
<script>
document.addEventListener('DOMContentLoaded', function(){
let script = document.querySelector('script[src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.js"]');
console.log('DEBUG START');
console.log(script);
});
</script>
</head>
<body>

<script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.js"></script>
<!-- Adding a script dynamically -->
<script>require.config({"waitSeconds":300,"baseUrl":"https:\/\/cdnjs.cloudflare.com\/ajax\/libs\/6to5\/","config":{"i18n":{"locale":"en"}}});require(["3.6.5/browser-polyfill"]);</script>
</body>
