<li class="title"><h2>1、演示说明</h2>
<ul class="list">
<li>这个演示式实现了 异步加载模式 下简单的勾选操作</li>
<li class="highlight_red">1)、加载子节点后，父节点的 halfCheck 立刻失效</li>
<li class="highlight_red">2)、勾选父节点，可以影响之后加载的子节点的勾选状态</li>
<li class="highlight_red">3)、勾选父节点，可以让其子节点的 halfCheck 属性失效</li>
</ul>
</li>
<li class="title"><h2>2、setting 配置信息说明</h2>
<ul class="list">
<li>实现半勾选功能，不需要配置任何参数。但半勾选功能属于辅助功能，无法单独使用，因此也需要根据自己的需求配置特定参数。</li>
</ul>
</li>
<li class="title"><h2>3、treeNode 节点数据说明</h2>
<ul class="list">
<li class="highlight_red">1)、请在节点初始化之前，设置 treeNode.halfCheck 属性，详细请参见 API 文档中的相关内容</li>
<li>2)、其他请参考 ‘Checkbox 勾选操作’</li>
