使用Ztree 默认的增删改操作 和 自定义增删改按钮(是操作数据库实例，比较简单的修改了下)...

此处 是默认的按钮：

var setting = {async: {enable: true,url:getPath()+"/manager/buildinfo/typeTree",dataFilter: null},view: {addHoverDom: addHoverDom,//当用户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//移出节点时,显示隐藏状态同zTree内部的编辑、删除按钮},data: {simpleData: {enable: true}}};//鼠标在节点获取焦点显示添加按钮function addHoverDom(treeId, treeNode) {var sObj = $("#" + treeNode.tId + "_span");if (treeNode.editNameFlag || $("#addBtn_"+treeNode.tId).length>0){return;}if (treeNode.editNameFlag || $("#delBtn_"+treeNode.tId).length>0){return;}if (treeNode.editNameFlag || $("#updBtn_"+treeNode.tId).length>0){return;} //删除if(treeNode.isShowDeleteBut){var delStr = "<span class='' id='delBtn_" + treeNode.tId+ "' title='删除建筑信息' style='color:red;' οnclick='deleteNode(\""+deleteOperate(treeNode.id)+"\",\""+treeNode.name+"\")'>删除</span>";sObj.after(delStr);}//修改if(treeNode.isShowUpdateBut){var updStr = "<span class='' id='updBtn_" + treeNode.tId+ "' title='修改建筑信息' style='color:red;' οnclick='updateNode(\""+deleteOperate(treeNode.id)+"\")'>修改</span>";sObj.after(updStr);}//添加if(treeNode.isShowInsertBut){var addStr = "<span class='' id='addBtn_" + treeNode.tId+ "' title='添加建筑信息'  style='color:red;' οnclick='addNode(\""+deleteOperate(treeNode.id)+"\",\""+treeNode.name+"\")';>添加</span>";sObj.after(addStr);}};//隐藏按钮function removeHoverDom(treeId, treeNode) {$("#addBtn_"+treeNode.tId).unbind().remove();$("#updBtn_"+treeNode.tId).unbind().remove();$("#delBtn_"+treeNode.tId).unbind().remove();};//添加function addNode(id,name){var url = getPath()+"/manager/buildinfo/toAddJsp?structureid="+id;location.href = url;}//修改function updateNode(id){var url = getPath()+"/manager/buildinfo/toUpdateJsp";location.href = url+"?id="+id+"&isAdd=2";}//删除function deleteNode(id,name){layer.confirm('您确定要删除 -->'+ name + "吗?", function(){ var url = getPath()+"/manager/buildinfo/deleteBuildInfo";var param = {"id":id,"time" : Math.random()};$.post(url,param,function(data){if("error" == data){layer.alert('对不起，你所删除的建筑信息,再被其他地方所使用,您不能删除!', 3);return false;}else if("success" == data){layer.msg('删除成功!', 2, -1);location.href =getPath()+ "/manager/peizhiManager/buildinfo/buildinfoTree.jsp";}else if("syncError" == data){layer.msg('删除操作失败!', 2, -1);}});});}$(document).ready(function(){//加载树结构数据$.fn.zTree.init($("#treeDemo"), setting);});

样式如下：

	<div class="content_wrap" id="treeDiv" style="display: block;"><div class="zTreeDemoBackground left"><ul id="treeDemo" class="ztree"></ul></div>
</div>

数据格式 JSON

 [{"name":"四川大学","id":"1a","pId":"0a","open":false,"checked":true,"isShowDeleteBut":true,"isShowUpdateBut":true,"isShowInsertBut":true,"isBuildInfoNodeId":false,"isBuildStructureId":false},{"name":"四川大学南校区","id":"2a","pId":"1a","open":false,"checked":false,"isShowDeleteBut":true,"isShowUpdateBut":true,"isShowInsertBut":true,"isBuildInfoNodeId":false,"isBuildStructureId":false},{"name":"电子科技大学","id":"3a","pId":"0a","open":false,"checked":false,"isShowDeleteBut":true,"isShowUpdateBut":true,"isShowInsertBut":true,"isBuildInfoNodeId":false,"isBuildStructureId":false},{"name":"电子科技大学北校区","id":"4a","pId":"3a","open":false,"checked":false,"isShowDeleteBut":true,"isShowUpdateBut":true,"isShowInsertBut":true,"isBuildInfoNodeId":false,"isBuildStructureId":false},{"name":"成都财经大学","id":"5a","pId":"0a","open":false,"checked":false,"isShowDeleteBut":true,"isShowUpdateBut":true,"isShowInsertBut":true,"isBuildInfoNodeId":false,"isBuildStructureId":false},{"name":"成都财经大学南校区","id":"6a","pId":"5a","open":false,"checked":false,"isShowDeleteBut":true,"isShowUpdateBut":true,"isShowInsertBut":true,"isBuildInfoNodeId":false,"isBuildStructureId":false}
]

数据自己在后台直接通过一个 对象封装就OK了

import java.util.List;/*** 站点树，节点对象* @author ibm**/
public class ZTreeNode {private String name;private String id;private String pId;private List<ZTreeNode> childList;private String icon;//是否是打开状态 默认不打开private boolean open = false;//判断是否选中private boolean checked = false;//判断是否是可选的 如果为 true 则此节点不可选private boolean nocheck = false;//控制是否显示 增删改按钮  默认都是不显示private boolean isShowDeleteBut = false;private boolean isShowUpdateBut = false;private boolean isShowInsertBut = false;//判断是否是建筑信息节点Idprivate boolean isBuildInfoNodeId;//判断是否是建筑结构节点Idprivate boolean isBuildStructureId;public String getId() {return id;}public void setId(String id) {this.id = id;}public String getpId() {return pId;}public void setpId(String pId) {this.pId = pId;}public String getName() {return name;}public void setName(String name) {this.name = name;}public List<ZTreeNode> getChildList() {return childList;}public void setChildList(List<ZTreeNode> childList) {this.childList = childList;}public String getIcon() {return icon;}public void setIcon(String icon) {this.icon = icon;}public boolean isOpen() {return open;}public void setOpen(boolean open) {this.open = open;}public boolean isShowDeleteBut() {return isShowDeleteBut;}public void setShowDeleteBut(boolean isShowDeleteBut) {this.isShowDeleteBut = isShowDeleteBut;}public boolean isShowUpdateBut() {return isShowUpdateBut;}public void setShowUpdateBut(boolean isShowUpdateBut) {this.isShowUpdateBut = isShowUpdateBut;}public boolean isShowInsertBut() {return isShowInsertBut;}public void setShowInsertBut(boolean isShowInsertBut) {this.isShowInsertBut = isShowInsertBut;}public boolean isBuildInfoNodeId() {return isBuildInfoNodeId;}public void setBuildInfoNodeId(boolean isBuildInfoNodeId) {this.isBuildInfoNodeId = isBuildInfoNodeId;}public boolean isBuildStructureId() {return isBuildStructureId;}public boolean isChecked() {return checked;}public void setChecked(boolean checked) {this.checked = checked;}public void setBuildStructureId(boolean isBuildStructureId) {this.isBuildStructureId = isBuildStructureId;}public boolean isNocheck() {return nocheck;}public void setNocheck(boolean nocheck) {this.nocheck = nocheck;}
}

以上直接是操作数据库的  比较简单的实现。
