克隆或复制对象中的方法(Javascript)

function cloneObject(source) {
  var target = {};
  for (var key in source) {
    if (typeof source[key] === 'function') {
      target[key] = source[key];
    }
  }
  return target;
}

// 使用示例
var source = {
  method1: function() {
    console.log('Method 1');
  },
  method2: function() {
    console.log('Method 2');
  }
};

var cloned = cloneObject(source);
cloned.method1(); // 输出：Method 1
cloned.method2(); // 输出：Method 2

var source = {
  method1: function() {
    console.log('Method 1');
  },
  method2: function() {
    console.log('Method 2');
  }
};

var cloned = Object.assign({}, source);
cloned.method1(); // 输出：Method 1
cloned.method2(); // 输出：Method 2

var source = {
  method1: function() {
    console.log('Method 1');
  },
  method2: function() {
    console.log('Method 2');
  }
};

var cloned = { ...source };
cloned.method1(); // 输出：Method 1
cloned.method2(); // 输出：Method 2
