将Javascript树对象转换为另一个树对象

// 定义原始树对象
const sourceTree = {
  id: 1,
  name: 'Root',
  children: [
    {
      id: 2,
      name: 'Node 1',
      children: [
        {
          id: 3,
          name: 'Node 1.1',
          children: []
        },
        {
          id: 4,
          name: 'Node 1.2',
          children: []
        }
      ]
    },
    {
      id: 5,
      name: 'Node 2',
      children: []
    }
  ]
};

// 定义目标树对象
const targetTree = {
  id: null,
  label: '',
  children: []
};

// 定义转换函数
function convertTree(source, target) {
  target.id = source.id;
  target.label = source.name;

  for (let i = 0; i < source.children.length; i++) {
    const sourceChild = source.children[i];
    const targetChild = {
      id: null,
      label: '',
      children: []
    };
    target.children.push(targetChild);
    convertTree(sourceChild, targetChild);
  }
}

// 执行转换
convertTree(sourceTree, targetTree);

// 打印结果
console.log(targetTree);
