一，首先理解ztree插件原理和作用，链接http://www.ztree.me/v3/demo.php#_305 下载ztree增删改的方法
如下代码：

<script>
var setting = {
async: {
enable: true,//开启异步加载处理
dataFilter: filter//用于对 Ajax 返回数据进行预处理的函数
},
view: {
expandSpeed: "",//zTree 节点展开、折叠时的动画速度，设置方法同 JQuery 动画效果中 speed 参数。
addHoverDom: addHoverDom,//用于当鼠标移动到节点上时，显示用户自定义控件，显示隐藏状态同 zTree 内部的编辑、删除按钮
removeHoverDom: removeHoverDom,//设置鼠标移到节点上，在后面显示一个按钮
selectedMulti: false// 禁止多点同时选中的功能
},
edit: {
enable: true//设置 zTree 进入编辑状态
},
data: {
simpleData: {
enable: true//使用简单 Array 格式的数据
}
},
callback: {
beforeRemove: beforeRemove,//用于捕获节点被删除之前的事件回调函数，并且根据返回值确定是否允许删除操作
beforeRename: beforeRename//用于捕获节点编辑名称结束（Input 失去焦点 或 按下 Enter 键）之后，更新节点名称数据之前的事件回调函数，并且根据返回值确定是否允许更改名称的操作
}
};
//修改异步获取到的节点name属性
function filter(treeId, parentNode, childNodes) {
if (!childNodes) return null;
for (var i = 0, l = childNodes.length; i < l; i++) {
childNodes[i].name = childNodes[i].name.replace(/\.n/g, '.');
}
return childNodes;
}
//删除节点信息
function beforeRemove(treeId, treeNode) {
var zTree = $.fn.zTree.getZTreeObj("treeDemo");
zTree.selectNode(treeNode);
return ("确认删除 节点 -- " + treeNode.name + " 吗？")
}
//修改节点信息
function beforeRename(treeId, treeNode, newName) {
if (newName.length == 0) {
alert("节点名称不能为空.");
return false;
}
var treeInfo = treeNode.id;
}
//添加新的节点
function addHoverDom(treeId, treeNode) {
var sObj = $("#" + treeNode.tId + "_span");
if (treeNode.editNameFlag || $("#addBtn_" + treeNode.tId).length > 0) return;
var addStr = "<span class='button add' id='addBtn_" + treeNode.tId
+ "' title='add node' onfocus='this.blur();'></span>";
sObj.after(addStr);
var btn = $("#addBtn_" + treeNode.tId);
if (btn) btn.bind("click", function () {
var zTree = $.fn.zTree.getZTreeObj("treeDemo");
return confirm("确认为 " + treeNode.name + " 添加子节点吗？")
});
};
//设置鼠标移到节点上，在后面显示一个按钮
function removeHoverDom(treeId, treeNode) {
$("#addBtn_" + treeNode.tId).unbind().remove();
};
var zNodes = [
<%=tree%>
];
//加载显示
$(document).ready(function () {
$.fn.zTree.init($("#treeDemo"), setting, zNodes);
});
</script>
