1、错误描述
Uncaught SyntaxError: Cannot use import statement outside a module2、错误原因
定义了一个JavaScript文件，声明几个变量，利用模块化导出变量
let name = '张华'
let age = 23
let sex = '女'
export {name, age, sex}接着，在页面文件中直接导入import；打开浏览器访问页面，控制台出现报错
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="../js/a1.js"></script>
<script src="../js/a2.js"></script>
<script>
import {name, age, sex} from '../js/a3.js'
console.log(name,age,sex)
</script>
</head>
<body>
</body>
</html>3、解决办法
需要在script标签上添加属性type="module"
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="../js/a1.js"></script>
<script src="../js/a2.js"></script>
<script type="module">
import {name, age, sex} from '../js/a3.js'
console.log(name,age,sex)
</script>
</head>
<body>
</body>
</html>
