如何使用Layui开发一个基于树形结构的导航菜单

var menuData = [
  {
    "id": 1,
    "name": "菜单1",
    "children": [
      {
        "id": 11,
        "name": "子菜单1.1"
      },
      {
        "id": 12,
        "name": "子菜单1.2",
        "children": [
          {
            "id": 121,
            "name": "子菜单1.2.1"
          },
          {
            "id": 122,
            "name": "子菜单1.2.2"
          }
        ]
      }
    ]
  },
  {
    "id": 2,
    "name": "菜单2",
    "children": [
      {
        "id": 21,
        "name": "子菜单2.1"
      },
      {
        "id": 22,
        "name": "子菜单2.2"
      }
    ]
  },
  {
    "id": 3,
    "name": "菜单3"
  }
];

<div id="navMenu"></div>

layui.use(['tree', 'form'], function(){
  var tree = layui.tree;
  
  tree.render({
    elem: '#navMenu',  // 绑定容器
    data: menuData,    // 导航菜单数据
    showCheckbox: false,  // 是否显示复选框
    id: 'navMenuTree',  // 自定义ID，用于相关操作
    isJump: true,  // 是否允许点击节点时弹出新窗口跳转
    click: function(obj){  // 点击回调函数
      // do something
      console.log(obj.data);  // 获取点击的节点数据
    }
  });
});

<style>
  .layui-tree li a {
    padding-left: 20px;
  }
  
  .layui-tree li a i {
    margin-right: 5px;
  }
  
  .layui-tree li a i.layui-icon-file {
    background-color: #1E9FFF;
    color: #fff;
  }
  
  .layui-tree li a i.layui-icon-folder {
    background-color: #FF5722;
    color: #fff;
  }
  
  .layui-tree li a i.layui-icon-file-text {
    color: #1E9FFF;
  }
</style>
