类及对象构建

用下面给定的方法构造一个对象.

方法有 getFirstName(), getLastName(), getFullName(), setFirstName(first), setLastName(last), and setFullName(firstAndLast).

所有有参数的方法只接受一个字符串参数.

所有的方法只与实体对象交互.

var Person = function(firstAndLast) {

    var name = firstAndLast;

    this.getFirstName = function() {

        var all = name.split(" ");

        return all[0];

    }

    this.getLastName = function() {

        var all = name.split(" ");

        return all[1];

    }

    this.getFullName = function() {

        return name;

    }

    this.setFirstName = function(firstAndLast) {

        var all = name.split(" ");

        all[0] = firstAndLast;

        name = all[0] + " " + all[1];

    }

    this.setLastName = function(firstAndLast) {

        var all = name.split(" ");

        all[1] = firstAndLast;

        name = all[0] + " " + all[1];

    }

    this.setFullName = function(firstAndLast) {

        name = firstAndLast;

    }

};

var bob = new Person('Bob Ross');

bob.getFullName();
