如何在JavaScript中迭代到对象方法

2024-04-25 • 问答

let person = {
  firstName: "Rella",lastName: "binson",age: 18,getFullName: function() {
    return this.firstName + ' ' + this.lastName;
  }
};

for (let key in person) {
  if (person.hasOwnProperty(key)) {
    console.log(key + ' ' + person[key])
  }
}
// it doesn't print 'getFullName()

考虑使用getter属性：

let person = {
  firstName: "Rella",lastName: "binson",age: 18,get getFullName() {
    return this.firstName + ' ' + this.lastName;
  }
};

for (let key in person) {
  if (person.hasOwnProperty(key)) {
    console.log(key + ' ' + person[key])
  }
}

参考：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get

这是使用现代Object.keys（）方法并将其收集到数组中的另一种方法

let person = {
  firstName: "Rella",getFullName: function() {
    return this.firstName + ' ' + this.lastName;
  }
}

const objectMethods = Object.keys(person).filter(item => {
  person.hasOwnProperty(item) &&
  typeof person[item] === 'function'
})
