问题描述
我正在尝试使用导出和导入,但是我收到错误消息
I'm trying to use export and import but it not working I get an error
这是我的代码HTML:
Here is my code HTML :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
@RenderBody()
<script src="~/scripts/user.js"></script>
<script src="~/scripts/main.js"></script>
</body>
</html>
User.ts:
export class User {
firstName: string;
lastName: string;
}
main.ts
import { User } from "./user";
这也是异常的屏幕截图:

推荐答案
您有几个选择:
选项1:使用模块加载程序,例如 Webpack , Browserify等.
Option 1: Use a module loader like Webpack, Browserify, etc.
选项2:如果只想将*.ts
编译为*.js
而没有任何模块导入或导出,请在tsconfig.json
中将compilerOptions.module
设置为"none".请注意,将compilerOptions.module
设置为无"时,将无法导出/导入模块.
Option 2: If you just want to compile *.ts
to *.js
without any module imports or exports, set compilerOptions.module
to "none" in your tsconfig.json
. Note that you won't be able to export/import modules when you set compilerOptions.module
to "none".
