Question

嗨，我是NodeJS的新手，我的node.js代码不起作用，因此，当我运行Node app.js时，它仅返回“ [Function]”

//This is the index.js file

var  number, origin, destination;

exports.setNumber = function (num){
    number = num;
};

exports.setOrigin = function (o){
   origin = o;
};

exports.setDestination = function (d){
    destination = d;
};

exports.getInfo = function(){
    return{
        number     : number,
        origin    : origin,
        destination    : destination
    };
};

//This is the app.js file

var flight = require('./javascript_1')

flight.setNumber(356);
flight.setDestination('There');
flight.setOrigin('Here');

console.log(flight.getInfo);

请帮助，因为我不知道我在做什么错

flight.getInfo是一个函数。您必须调用它。尝试将最后一行替换为：

console.log(flight.getInfo());

节点在命令行中返回“ [Function]”
