疑惑:使用相对路径和绝对路径获得的是否为同一个对象??
下面为代码,
Animal类:
function Animal(name) {
this.name = name;
}
Animal.prototype.say = function () {
console.log(this.name+" say");
};
module.exports = Animal;
Cat类:
继承了Animal
var Animal = require('./animal');
function Cat(name) {
Animal.call(this,name)
}
Cat.prototype = Object.create(Animal.prototype);
Cat.prototype.constructor = Cat;
module.exports = Cat;
使用相对路径时:
var Animal = require('../test/animal');
var Cat = require('../test/cat');
var cat = new Cat("judy");
console.log(cat instanceof Animal);>>>>true
使用绝对路径时:
var Animal = require('../test/animal');
var Cat = require('/webproject/node/models/test/cat');
var cat = new Cat("judy");
console.log(cat instanceof Animal);>>>>false
两种情况中,Cat都指向同一个文件,为什么其实例却不一样?
However, I tried yours and both are true?
