如何获取每个treeview父节点的子节点列表

// 导入腾讯云相关产品
const tencentCloud = require('tencent-cloud-sdk');

// 创建一个treeview控件并添加父节点和子节点
const treeView = new TreeView();
const parentNode1 = treeView.addNode('Parent Node 1');
parentNode1.addNode('Child Node 1.1');
parentNode1.addNode('Child Node 1.2');
const parentNode2 = treeView.addNode('Parent Node 2');
parentNode2.addNode('Child Node 2.1');
parentNode2.addNode('Child Node 2.2');

// 获取所有父节点
const parentNodes = treeView.get_nodes();

// 遍历每个父节点并获取其子节点列表
parentNodes.forEach(parentNode => {
  const childNodes = parentNode.get_nodes();
  
  // 打印子节点列表
  console.log(`Parent Node: ${parentNode.get_text()}`);
  console.log('Child Nodes:');
  childNodes.forEach(childNode => {
    console.log(childNode.get_text());
  });
});
