类及对象构建算法挑战

挑战&＃xff1a;

用下面给定的方法构造一个对象.

方法有 &＃xff1a;

getFirstName()
getLastName()
getFullName()
setFirstName(first)
setLastName(last)
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.

答案&＃xff1a;

var Person &＃61; function(firstAndLast) {var arr &＃61; firstAndLast.split(&＃39; &＃39;),first &＃61; arr[0],last &＃61; arr[1],fullName &＃61; firstAndLast;this.getFirstName &＃61; () &＃61;> first;this.getLastName &＃61; () &＃61;> last;this.getFullName &＃61; () &＃61;> fullName;this.setFirstName &＃61; (firstName) &＃61;> fullName &＃61; firstName &＃43; &＃39; &＃39; &＃43; last;this.setLastName &＃61; (lastName) &＃61;> fullName &＃61; first &＃43; &＃39; &＃39; &＃43; lastName;this.setFullName &＃61; (fn) &＃61;> {arr &＃61; fn.split(&＃39; &＃39;);fullName &＃61; fn;first &＃61; arr[0];last &＃61; arr[1];};
};var bob &＃61; new Person(&＃39;Bob Ross&＃39;);
bob.getFullName();

运行结果&＃xff1a;
