回答by Dolan Antenucci
If the variable is global, and you include the JS file with the variable first in your HTML file, then it is accessible via the second JS file:
如果变量是全局变量，并且您首先在 HTML 文件中包含带有变量的 JS 文件，则可以通过第二个 JS 文件访问它：
<script type="text/javascript" src="somefile_with_variable.js"/>
<script type="text/javascript" src="somefile_reading_variable.js"/>

Inside a browser, all the .js files share the same global space. Just refer to it by name.
在浏览器中，所有 .js 文件共享同一个全局空间。只需按名称引用它。

Include both files on a certain page and you can access the array normally by its name.
在某个页面上包含这两个文件，您可以通过其名称正常访问该数组。

In order for this to work define your array as "var" (global variable). Go to the JS file where the array is and export it.
为了使其工作，将您的数组定义为“var”（全局变量）。转到数组所在的JS文件并导出它。
var globalArray;
export{globalArray, otherFunctionsYouExport};
Now go to the JS file you want the access to the array and import the global array. If you have multiple functions to import, use * and it will export everything between the brackets above.
现在转到要访问数组的 JS 文件并导入全局数组。如果您有多个函数要导入，请使用 * 它将导出上面括号之间的所有内容。
import * as chooseName from './path of your JS file you export from';
// to use it write this
chooseName.globalArray // put here the rest of your code
