Javascript 如何从包含对象列表的文件中导出对象，并在另一个文件中导入相同的对象以使用它？

如何从包含对象列表的文件中导出对象，并在另一个文件中导入相同的对象，以便能够使用它

//源文件示例

const obj1 = {
  element1: { property1: value1, property2: value2, property3: value3},
  element2: { property1: value1, property2: value2, property3: value3},
  element3: { property1: value1, property2: value2, property3: value3},
  element4: { property1: value1, property2: value2, property3: value3},
  element5: { property1: value1, property2: value2, property3: value3},
}

const obj2 = {
  element1: { property1: value1, property2: value2, property3: value3},
  element2: { property1: value1, property2: value2, property3: value3},
  element3: { property1: value1, property2: value2, property3: value3},
  element4: { property1: value1, property2: value2, property3: value3},
  element5: { property1: value1, property2: value2, property3: value3},
}

export ????

'use strict';
import ???

console.log(importedObject);

//从源文件导入主文件的示例

const obj1 = {
  element1: { property1: value1, property2: value2, property3: value3},
  element2: { property1: value1, property2: value2, property3: value3},
  element3: { property1: value1, property2: value2, property3: value3},
  element4: { property1: value1, property2: value2, property3: value3},
  element5: { property1: value1, property2: value2, property3: value3},
}

const obj2 = {
  element1: { property1: value1, property2: value2, property3: value3},
  element2: { property1: value1, property2: value2, property3: value3},
  element3: { property1: value1, property2: value2, property3: value3},
  element4: { property1: value1, property2: value2, property3: value3},
  element5: { property1: value1, property2: value2, property3: value3},
}

export ????

'use strict';
import ???

console.log(importedObject);

使用ES6静态命名/（ES6模块）语法：

/file-a.js

const obj1 = {
  element1: { property1: value1, property2: value2, property3: value3},
  element2: { property1: value1, property2: value2, property3: value3},
  element3: { property1: value1, property2: value2, property3: value3},
  element4: { property1: value1, property2: value2, property3: value3},
  element5: { property1: value1, property2: value2, property3: value3}
}

const obj2 = {
  element1: { property1: value1, property2: value2, property3: value3},
  element2: { property1: value1, property2: value2, property3: value3},
  element3: { property1: value1, property2: value2, property3: value3},
  element4: { property1: value1, property2: value2, property3: value3},
  element5: { property1: value1, property2: value2, property3: value3}
}

export {obj1, obj2};

import {obj1, obj2} from './file-a.js';

console.log(obj1);
console.log(obj2);

/file-b.js

const obj1 = {
  element1: { property1: value1, property2: value2, property3: value3},
  element2: { property1: value1, property2: value2, property3: value3},
  element3: { property1: value1, property2: value2, property3: value3},
  element4: { property1: value1, property2: value2, property3: value3},
  element5: { property1: value1, property2: value2, property3: value3}
}

const obj2 = {
  element1: { property1: value1, property2: value2, property3: value3},
  element2: { property1: value1, property2: value2, property3: value3},
  element3: { property1: value1, property2: value2, property3: value3},
  element4: { property1: value1, property2: value2, property3: value3},
  element5: { property1: value1, property2: value2, property3: value3}
}

export {obj1, obj2};

import {obj1, obj2} from './file-a.js';

console.log(obj1);
console.log(obj2);

您的环境是NodeJS吗？您有配置的构建过程吗？是的，简单的NodeJ，源文件服务于对象列表，其中另一个文件将从该源文件仅导入几个对象。它给出了：SyntaxError:无法在模块外使用导入语句。我不知道为什么…是的，因为ES6模块支持最近才添加。您有两个选项：向

包.json

文件添加

“type”：“module”

，或者重命名文件以使用

.mjs

扩展名而不是

.js

。其他选择包括传输代码（参见BabelJS）或不使用ES6模块（不推荐）。如果问题仍然存在，请尝试更新

包.json中的Node.Added
“type”：“module”
，并解决了问题！非常感谢！：）
