【JS学习笔记】自定义对象和引用对象

function Person(firstName, lastName){
    this.firstName = firstName;
    this.lastName = lastName;
}
Person.prototype.getFullName = function () {
    return this.firstName + " " + this.lastName;
}
Person.prototype.greet = function (person) {
    document.write("Hello" + person.getFullName()
    +", I m" +this.getFullName());
}

var johnDoe = new Person("john","Doe");
var janeDoe = new Person("jane","Doe");

johnDoe.greet(janeDoe);
