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;' onclick='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;' onclick='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;' onclick='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Id
	private boolean isBuildInfoNodeId;
	//判断是否是建筑结构节点Id
	private 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。
