<div class="desc">
|

|
|
<h4><b>parentNode</b><span>JSON</span></h4>
|
|||
|
|
<p>指定需要异步加载的父节点 JSON 数据</p>
|
|||
|
|
<p class="highlight_red">1、parentNode = null 时，相当于从根节点 Root 进行异步加载</p>
|
|||
|
|
<p class="highlight_red">2、parentNode.isParent = false 时，不进行异步加载</p>
|
|||
|
|
<p class="highlight_red">3、请务必保证此节点数据对象 是 zTree 内部的数据对象</p>

|
<h4 class="topLine"><b>reloadType</b><span>String</span></h4>
|
|||
|
|
<p>reloadType = "refresh" 表示清空后重新加载。</p>
|
|||
|
|
<p>reloadType != "refresh" 时，表示追加子节点处理。</p>
|
|||
|
|
<h4 class="topLine"><b>isSilent</b><span>Boolean</span></h4>
|
|||
|
|
<p>设定异步加载后是否自动展开父节点。</p>
|
|||
|
|
<p>isSilent = true 时，不展开父节点，其他值或缺省状态都自动展开。</p>

<h3>function 举例</h3>

<h4>1. 重新异步加载 zTree </h4>
|

|

<h4>2. 重新异步加载当前选中的第一个节点</h4>
|
|||
|
|
<pre xmlns=""><code>var treeObj = $.fn.zTree.getZTreeObj("tree");
|
|||
|
|
var nodes = treeObj.getSelectedNodes();
