我不能使用在同一对象中创建的方法来修改对象的属性。我正在尝试使用foreach then console.log是未定义的

const myObject = {
  property: 'value',
  updateProperty: function(newValue) {
    this.property = newValue;
  },
  logProperties: function() {
    this.property.forEach((item, index) => {
      console.log(item);
      this.updateProperty(`new value at index ${index}`);
    });
  }
};

myObject.logProperties();
console.log(myObject.property); // 输出更新后的属性值

const myObject = {
  property: ['value1', 'value2'],
  updateProperty: function(newValue) {
    this.property = newValue;
  },
  logProperties: function() {
    this.property.forEach(function(item, index) {
      console.log(item);
      this.updateProperty(`new value at index ${index}`);
    }, this); // 使用.bind(this)来绑定正确的this
  }
};

myObject.logProperties();
console.log(myObject.property); // 输出更新后的属性值

const myObject = {
  property: ['value1', 'value2'],
  updateProperty: function(newValue) {
    this.property = newValue;
  },
  logProperties: function() {
    const self = this; // 保存this引用
    this.property.forEach(function(item, index) {
      console.log(item);
      self.updateProperty(`new value at index ${index}`); // 使用self代替this
    });
  }
};

myObject.logProperties();
console.log(myObject.property); // 输出更新后的属性值
