<h3>Function Parameter Descriptions</h3>
<div class="desc">
<h4><b>event</b><span>js event Object</span></h4>
<p>event Object</p>
<h4 class="topLine"><b>treeId</b><span>String</span></h4>
<p>zTree unique identifier: <b class="highlight_red">treeId</b>, the tree is what the targetNode is belong to, easy for users to control.</p>
<h4 class="topLine"><b>treeNodes</b><span>Array(JSON)</span></h4>
<p>A collection of the nodes which has been dragged</p>
<p class="highlight_red">The treeNodes are the data of the nodes which be dragged, when move nodes.</p>

<h4 class="topLine"><b>moveType</b><span>String</span></h4>
<p>the relative position of move to the target node</p>
<p class="highlight_red">"inner": will be child of targetNode</p>
<p class="highlight_red">"prev": will be sibling node, and be in front of targetNode</p>
<p class="highlight_red">"next": will be sibling node, and be behind targetNode</p>
<p class="highlight_red">If moveType is null, means drag & drop is cancel.</p>
<h4 class="topLine"><b>isCopy</b><span>Boolean</span></h4>
<p>the flag used to judge copy node or move node</p>
<p class="highlight_red">true: copy node; false: move node</p>
</div>
<h3>Examples of setting & function</h3>
<h4>1. When drag-drop nodes complete, alert the number of dragged nodes and info about targetNode.</h4>
<pre xmlns=""><code>function zTreeOnDrop(event, treeId, treeNodes, targetNode, moveType) {
alert(treeNodes.length + "," + (targetNode ? (targetNode.tId + ", " + targetNode.name) : "isRoot" ));
};
var setting = {
callback: {
onDrop: zTreeOnDrop
