javascript - 为什么javascript绑定(bind)不起作用

Question

功能:

function talk(){ 
        console.log(this.name + " dice: ");
}

var Person = function(name, surname){
    this.name = name;
    this.surname = surname;
}

var p = new Person("Mark", "Red");

talk.bind(p);

绑定(bind)有什么问题？

Answer 1

它确实有效，talk.bind(p) 返回绑定(bind)函数:

talk.bind(p)();
