Jquery 可拖拽的Ztree（移动，复制）两种选择

首先要引入ztree依赖的js

<link rel="stylesheet" type="text/css" href="<c:url value="/js/common/zTree-v3.5.14/css/zTreeStyle/zTreeStyle.css"/>"/>
 <script src="<c:url value="/js/common/zTree-v3.5.14/js/jquery.ztree.all-3.5.min.js"/>"
<link rel="stylesheet" type="text/css" href="<c:url value="/js/common/bootstrap-2.3.2/css/bootstrap.min.css"/>"/>
<script src="<c:url value="/js/common/bootstrap-2.3.2/js/bootstrap.min.js"/>" type="text/javascript"></script>
<script src="<c:url value="/js/common/jquery/jquery-1.8.2.min.js"/>" type="text/javascript"></script><link rel="stylesheet" type="text/css" href="<c:url value="/js/common/zTree-v3.5.14/css/zTreeStyle/zTreeStyle.css"/>"/>
 <script src="<c:url value="/js/common/zTree-v3.5.14/js/jquery.ztree.all-3.5.min.js"/>"
<link rel="stylesheet" type="text/css" href="<c:url value="/js/common/bootstrap-2.3.2/css/bootstrap.min.css"/>"/>
<script src="<c:url value="/js/common/bootstrap-2.3.2/js/bootstrap.min.js"/>" type="text/javascript"></script>
<script src="<c:url value="/js/common/jquery/jquery-1.8.2.min.js"/>" type="text/javascript"></script>

只贴关键代码吧，自己把有用的属性全部打印出来了，也加了不少注释。

$.fn.zTree.init($("#ztree"), {
            data: {
                simpleData: {
                    enable: true
                }
            },
            view:{
                selectedMulti :false
            },
            edit: { //此属性添加后，树才可以被拖拽
                enable: true,
                showRemoveBtn: false,
                showRenameBtn: false,
                drag: {

                    next: true,
                    inner: true
                }
            },
            callback: {
                onClick: function(event, treeId, treeNode, clickFlag) {
                    switch (treeNode.gradeType) {
                        case "db":
                            clickCatgryNode(treeNode.id);
