javascript - 在对象上定义函数

Question

var person = {
    name:'Bob',
    age:29,
    job:'software engineer',
    sayName:sayName()
}

function sayName(){
    alert(this.name);
}

上面这种代码形式为什么在没调用person.sayName()的时候下面这个alert方法就会执行呢？

Answer 1

var person = {
    name:'Bob',
    age:29,
    job:'software engineer',
    sayName:sayName()//执行sayName..
}

你执行了sayName函数啊。。
