freecodecamp中的创建一个人员对象？-灵析社区
Fiona 该如何修改代码 const Person = function(first, last) { var first = first; var last = last; this.getFullName = function(str) { return str; }; this.getFirstName = function() { return first.split(' ')[0]; }; this.getLastName = function() { return last.split(' ')[1]; }; this.setFirstName = function(str) { first = `${str} ${first.split(' ')[1]}` }; this.setLastName = function(str) { last = `${last.split(' ')[0]} ${str}` }; this.setFullName = function(str) { return str; }; }; 修改正确
无敌奥特MEN你得单独用变量保存一下，然后后面的 setter/getter 方法都直接访问存的那个变量就好了呀，你现在这样的 setter 进来的你都没保存。
const Person = function (first, last) {
let _first = first;
let _last = last;
this.getFirstName = function () {
return _first;
};
this.getLastName = function () {
return _last;
};
this.getFullName = function () {
return _first + ' ' + _last;
};
this.setFirstName = function (first) {
_first = first;
};
this.setLastName = function (last) {
_last = last;
};
this.setFullName = function (first, last) {
_first = first;
_last = last;
};
return '';
};
