Person.prototype = Object({
getName: () {
.name;
}
});
而constructor始终指向创建自身的构造函数，所以此时Person.prototype.constructor === Object，即是：
复制代码 代码如下:
Person(name) {
.name = name;
};
Person.prototype = {
getName: () {
.name;
}
};
p = Person();
console.log(p.constructor === Object);
console.log(Person.prototype.constructor === Object);
console.log(p.constructor.prototype.constructor === Object);
怎么修正这种问题呢？方法也很简单，重新覆盖Person.prototype.constructor即可：
复制代码 代码如下:
Person(name) {
.name = name;
};
Person.prototype = Object({
getName: () {
.name;
}
});
Person.prototype.constructor = Person;
p = Person();
console.log(p.constructor === Person);
console.log(Person.prototype.constructor === Person);
console.log(p.constructor.prototype.constructor === Person);
