Jquery 可拖拽的Ztree（移動，複製）兩種選擇

首先要引入ztree依賴的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>

只貼關鍵代碼吧，自己把有用的屬性全部打印出來了，也加了不少註釋。

$.fn.zTree.init($("#ztree"), {
            data: {
                simpleData: {
                    enable: true
                }
            },
            view:{
                selectedMulti :false
            },
            edit: { //此屬性添加後，樹纔可以被拖拽
                enable: true,
                showRemoveBtn: false,
                showRenameBtn: false,

            },
            callback: {
