Javascript从字符串动态调用对象方法

Question

我可以动态调用方法名称为字符串的对象方法吗？我会这样想象:

var FooClass = function() {
    this.smile = function() {};
}

var method = "smile";
var foo = new FooClass();

// I want to run smile on the foo instance.
foo.{mysterious code}(); // being executed as foo.smile();

Answer 1

如果属性名称存储在变量中，请使用[]

foo[method]();
