我在Stack Overflow / Google上阅读并看到了一种方法，包括一个js文件，用于在另一个文件中使用它的内容。

I have admin.js and index.js, in admin.js I need to access an array in index.js.

我有admin.js和index.js，在admin.js我需要访问index.js中的数组。

In index.js I have:

在index.js我有：

exports.chatrooms = function(){
    return usernames;
}

In admin.js I have:

在admin.js我有：

var indexFileInclude = require('index.js');
var chatrooms = indexFileInclude.chatrooms();
console.log(JSON.stringify(chatrooms));

I get an error:

我收到一个错误：

Missing error handler on `socket`.
Error: Cannot find module 'index.js'

With require() if you do not specify a path it will assume you're targeting the node_modules folder. To instead pull a module in the same folder, you would use the ./ notation to specify you want to target the current folder.

使用require（）如果您没有指定路径，它将假定您的目标是node_modules文件夹。要将模块拉入同一文件夹，您可以使用./表示法指定要定位当前文件夹。

var indexFileInclude = require('./index');
