JavaScript:从带有缩进的树对象生成HTML

function generateHTML(tree) {
  let html = '';

  // 递归遍历树节点
  function traverse(node) {
    // 处理节点的属性
    let attributes = '';
    for (let attr in node.attributes) {
      attributes += `${attr}="${node.attributes[attr]}" `;
    }

    // 处理节点的子节点
    let children = '';
    if (node.children) {
      for (let child of node.children) {
        children += traverse(child);
      }
    }

    // 生成HTML标签
    html += `<${node.tag} ${attributes}>${children}</${node.tag}>`;
  }

  traverse(tree);

  return html;
}

// 示例树对象
const tree = {
  tag: 'div',
  attributes: {
    class: 'container',
  },
  children: [
    {
      tag: 'h1',
      attributes: {},
      children: ['Hello, World!'],
    },
    {
      tag: 'p',
      attributes: {},
      children: ['This is a paragraph.'],
    },
  ],
};

// 生成HTML
const generatedHTML = generateHTML(tree);
console.log(generatedHTML);
