报错:Uncaught SyntaxError: Cannot use import statement outside a module 详解
Uncaught SyntaxError: Cannot use import statement outside a module 是一个JS错误。这个错误的原因是在非模块中使用了import语句。
为了解决这个错误,您可以将脚本的类型设置为module,页面中的script标签添加type="module"属性。例如,在index.html文件中可以这样编写脚本代码:
```
<script type="module">
import { add } from './test.js';
console.log(add(1,2)); // 打印出3
</script>
```
同时,确保导入的模块(test.js)也是一个ES6模块,需要使用export语句将需要导出的函数或变量暴露出来。例如,在test.js文件中可以这样编写代码:
```
export const add = (x, y) => {
return x + y;
}
```
通过以上方法,您可以解决Uncaught SyntaxError: Cannot use import statement outside a module错误,并且成功使用import语句在模块中导入其他脚本中的函数或变量。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
