I would recomend have separate external js files instead of an embedded <script> tag, but maybe this can help我建议使用单独的外部 js 文件而不是嵌入的<script>标签，但这也许会有所帮助

If you want to call the file in an another js file then you have to refer that file in the calling file.如果要在另一个js文件中调用该文件，则必须在调用文件中引用该文件。
Ex.前任。
Refer the files in the head section.请参阅head部分中的文件。
<head>
<script src="File2.js" type="text/javascript"></script>
<script src="File1.js" type="text/javascript"></script>
</head>
you can have your body tag something like this:你可以让你的body标签是这样的：
<body>
<script type="text/javascript">
Method2(); // Where you want to call method from another JS.
</script>
</body>
then, using first file然后，使用第一个文件
File1.js文件1.js
function Method1(number) {
alert("Method1");
}
File2.js文件2.js
function Method2() {
Method1("Method1 is called in Method2");
}
