javascript转换为父子数组

function convertToParentChildArray(data) {
  const result = [];

  function traverse(node, parent) {
    const obj = {
      parent: parent,
      child: node
    };
    result.push(obj);

    if (node.children && node.children.length > 0) {
      node.children.forEach(child => {
        traverse(child, node);
      });
    }
  }

  data.forEach(item => {
    traverse(item, null);
  });

  return result;
}

// 示例用法
const jsonData = [
  { id: 1, name: "Parent 1", children: [
    { id: 2, name: "Child 1.1", children: [] },
    { id: 3, name: "Child 1.2", children: [] }
  ]},
  { id: 4, name: "Parent 2", children: [
    { id: 5, name: "Child 2.1", children: [] },
    { id: 6, name: "Child 2.2", children: [] }
  ]}
];

const parentChildArray = convertToParentChildArray(jsonData);
console.log(parentChildArray);
