<li class="highlight_red">使用异步加载，必须设置 setting.async 中的各个属性，详细请参见 API 文档中的相关内容</li>

|
<li>异步加载功能对于 treeNode 节点数据没有特别要求，如果采用简单 JSON 数据，请设置 setting.data.simple 中的属性</li>
|
<li>如果异步加载每次都只返回单层的节点数据，那么可以不设置简单 JSON 数据模式</li>

<ul class="list">
|
<li class="highlight_red">观察 autoParam 和 otherParam 请使用 firebug 或 浏览器的开发人员工具</li>

<li class="highlight_red">此 Demo 只能加载到第 4 级节点（level=3）</li>
