已关闭 3 年前。

目录

 - folder
  - index.html
  - index.js
  - index1.js

index.html

   <!-- main content --->
   <script type='module' src='./index.js'></script>

index.js

   import {show} from "./index1"

   show();

index1.js

   export default function show(){
       console.log('hello world');
   }

描述

当在浏览器上运行index.html时，不起作用，并且我收到此错误:

Access to script at 'file:///Users/xxx/Documents/code/canvas/test/index.js' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.

从其他模块导入模块。就像使用 nodejs env 运行一样。

Answer 1

将脚本导入为模块:文件应导出为module.exports
