如何将一个对象数组的树结构克隆到另一个对象数组中，并将属性更改为被克隆的对象？

function cloneTree(originalArray) {
  var clonedArray = [];
  
  for (var i = 0; i < originalArray.length; i++) {
    var originalObj = originalArray[i];
    var clonedObj = {};
    
    // 复制原始对象的属性到克隆对象
    for (var key in originalObj) {
      if (originalObj.hasOwnProperty(key)) {
        clonedObj[key] = originalObj[key];
      }
    }
    
    // 如果原始对象有子节点，递归调用克隆函数
    if (originalObj.children && originalObj.children.length > 0) {
      clonedObj.children = cloneTree(originalObj.children);
    }
    
    clonedArray.push(clonedObj);
  }
  
  return clonedArray;
}

// 示例用法
var originalArray = [
  {
    id: 1,
    name: 'Node 1',
    children: [
      {
        id: 2,
        name: 'Node 1.1',
        children: []
      },
      {
        id: 3,
        name: 'Node 1.2',
        children: [
          {
            id: 4,
            name: 'Node 1.2.1',
            children: []
          }
        ]
      }
    ]
  }
];

var clonedArray = cloneTree(originalArray);
console.log(clonedArray);
