java动态生成树_Dtree+Jquery动态生成树节点例子

分手后的思念是犯贱 2022-11-05 13:00 193阅读 0赞

1.先来介绍一下. dtree 的用法.(我引用了以前我收集的一篇文章.还比较详细,出处不记得啦).文章下面会附带dtree用法的例子.

Dtree目录树的总结

一：函数

1：页面中

tree.add(id,pid,name,url,title,target,icon,iconOpen,open);

参数说明：

id         ：节点自身的id

pid       ：节点的父节点的id

name    ：节点显示在页面上的名称

url        ：节点的链接地址

title      ：鼠标放在节点上所出现的提示信息

target   ：节点链接所打开的目标frame(如框架目标mainFrame,\_blank,\_self 类)

icon      ：节点关闭时的显示图片的路径

iconOpen：节点打开时的显示图片的路径

open    ：布尔型，节点是否打开(默认为false)

注：open项：顶级节点一般采用true，即pid是－1的节点

2：dtree.js文件中

约87－113行是一些默认图片的路径，注意要指对。

二：页面中的书写

1：默认值的书写规则(从左至右，依次省略)

即 tree.add(id,pid,name,url);后面5个参数可以省略

2：有间隔时的默认值(如存在第6个参数，但第5个参数想用默认值)

即 tree.add(id,pid,name,url,"",target);必须这样写

3：样式表

(1)：可以将dtree.css中的样式附加到你的应用中的主css中，如a.css

(2)：也可以同时引用dtree.css与a.css两个文件，但前提条件是两个css文件中不能有重复的样式

Html代码 ![icon\_copy.gif][icon_copy.gif]

4：页面代码书写的位置是：一般写在表格的td之中

Javascript代码 ![icon\_copy.gif][icon_copy.gif]

tree =newdTree('tree');

tree.add("1","-1","京津","","","","","",true);

tree.add("11","1","A","","","","","",true);

tree.add("110","11","A-1","content.jsp?moduleName=XXX","","mainFrame");

tree.add("111","11","A-2","javascript:void(0)","","链接在哪里显示");

tree.add("112","11","A-3","javascript:void(0)","","mainFrame");

tree.add("113","11","A-4","/.jsp","","mainFrame");

tree.add("114","11","A-5","/.jsp","","mainFrame");

tree.add("115","11","A-6","/.jsp","","mainFrame");

tree.add("12","1","B","","","","","",true);

tree.add("121","12","B-1","javascript:调用本页内的js函数","","mainFrame");

tree.add("122","12","B-2");

tree.add("13","1","C","","","","","",true);

tree.add("131","13","C-1","javascript:void(0)","","mainFrame");

tree.add("132","13","C-2","javascript:void(0)","","mainFrame");

tree.add("133","13","C-3","javascript:void(0)","","mainFrame");

tree.add("14","1","D","","","","","",true);

tree.add("141","14","D-1","javascript:void(0)","","mainFrame");

document.write(tree);

tree = new dTree('tree');

tree.add("1","-1","京津","","","","","",true);

tree.add("11","1","A","","","","","",true);

tree.add("110","11","A-1","content.jsp?moduleName=XXX","","mainFrame");

tree.add("111","11","A-2","javascript:void(0)","","链接在哪里显示");

tree.add("112","11","A-3","javascript:void(0)","","mainFrame");

tree.add("113","11","A-4","/.jsp","","mainFrame");

tree.add("114","11","A-5","/.jsp","","mainFrame");

tree.add("115","11","A-6","/.jsp","","mainFrame");

tree.add("12","1","B","","","","","",true);

tree.add("121","12","B-1","javascript:调用本页内的js函数","","mainFrame");

tree.add("122","12","B-2");

tree.add("13","1","C","","","","","",true);

tree.add("131","13","C-1","javascript:void(0)","","mainFrame");

tree.add("132","13","C-2","javascript:void(0)","","mainFrame");

tree.add("133","13","C-3","javascript:void(0)","","mainFrame");

tree.add("14","1","D","","","","","",true);

tree.add("141","14","D-1","javascript:void(0)","","mainFrame");

document.write(tree);

说明：这是静态的代码，动态的可用循环加入。其他 tree.add(id,pid,name,url,"","","","",true);

三：css文件的注解

不罗嗦啦..上面的只是让你大概了解一下.dtree怎么用.

dtree+JQuery动态生成树.思路其实很简单...  首先把树的节点信息存储到数据库,然后在servlet或jsp中获取数据库表中的数据,把这些信息写成在xml文件中.然后界面jsp页面通过JQuery实现对改servlet的请求.并且回调方法中接受xml数据对象.并且遍历xml文件,取得xml文件中的节点的属性或文本数据.再循环的对dtree添加节点.。

1 . 在 MYSQL 中的test数据库中创建表.tree\_table.

SQL语句.

Sql代码 ![icon\_copy.gif][icon_copy.gif]

tree\_tableCREATETABLE\`tree\_table\` (

\`id\`int(11)NOTNULLauto\_increment,

\`nodeId\`varchar(12)NOTNULL,

\`parentId\`varchar(12)NOTNULL,

\`hrefAddress\`varchar(85)  ,

\`nodeName\`varchar(20)  ,

PRIMARYKEY(\`id\`)

) ENGINE=InnoDBDEFAULTCHARSET=gbk

tree\_table CREATE TABLE \`tree\_table\` (

\`id\` int(11) NOT NULL auto\_increment,

\`nodeId\` varchar(12) NOT NULL ,

\`parentId\` varchar(12) NOT NULL ,

\`hrefAddress\` varchar(85) ,

\`nodeName\` varchar(20) ,

PRIMARY KEY (\`id\`)

) ENGINE=InnoDB DEFAULT CHARSET=gbk

2.连接数据库的类.主要是读取表中的数据.

Java代码 ![icon\_copy.gif][icon_copy.gif]

packagecom.dao;

importjava.sql.Connection;

rs.close();

pre.close();

conn.close();

\} catch (SQLException e) \{

e.printStackTrace();

\}finally\{

pre = null;

return list;

3. 节点。JAVABEAN.类.

Java代码 ![icon\_copy.gif][icon_copy.gif]

packagecom.dao;

publicclassNodes \{

privateintid;

privateString nodeId;

privateString parentId;

privateString hrefAddress;

privateString nodeName;

publicintgetId() \{

returnid;

publicvoidsetId(intid) \{

this.id = id;

publicString getNodeId() \{

returnnodeId;

publicvoidsetNodeId(String nodeId) \{

this.nodeId = nodeId;

publicString getParentId() \{

returnparentId;

publicvoidsetParentId(String parentId) \{

this.parentId = parentId;

publicString getHrefAddress() \{

publicvoidsetHrefAddress(String hrefAddress) \{

this.hrefAddress = hrefAddress;

publicString getNodeName() \{

returnnodeName;

publicvoidsetNodeName(String nodeName) \{

package com.dao;

public class Nodes \{

private int id;

public int getId() \{

return id;

public void setId(int id) \{

this.id = id;

public String getNodeId() \{

return hrefAddress;

public void setHrefAddress(String hrefAddress) \{

this.hrefAddress = hrefAddress;

public String getNodeName() \{

return nodeName;

public void setNodeName(String nodeName) \{

this.nodeName = nodeName;

4.创建一个Serlvet 来生成xml文件.

注意: response.setContentType("text/xml;charset=utf-8");

publicvoiddoGet(HttpServletRequest request, HttpServletResponse response)

throwsServletException, IOException \{

doPost(request, response);

publicvoiddoPost(HttpServletRequest request, HttpServletResponse response)

throwsServletException, IOException \{

request.setCharacterEncoding("utf-8");

response.setContentType("text/xml;charset=utf-8");

PrintWriter out = response.getWriter();

DaoTest test =newDaoTest();

ArrayList list=  test.getNodeInfo();

if(list!=null&&list.size()>0)\{

out.println("<?xml  version=\\"1.0\\" encoding=\\"UTF-8\\"?>");

out.println("");

for(inti=0;i

Nodes node = list.get(i);

out.println(""+node.getNodeName()+"");

out.println("");

package com.handler;

import java.io.IOException;

import java.util.ArrayList;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import com.dao.DaoTest;

import com.dao.Nodes;

public class NodesPrint extends HttpServlet \{

private static final long serialVersionUID = 1L;

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException \{

doPost(request, response);

public void doPost(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException \{

request.setCharacterEncoding("utf-8");

response.setContentType("text/xml;charset=utf-8");

PrintWriter out = response.getWriter();

DaoTest test = new DaoTest();

ArrayList list= test.getNodeInfo();

if(list!=null&&list.size()>0)\{

out.println("<?xml version=\\"1.0\\" encoding=\\"UTF-8\\"?>");

out.println("");

for(int i=0;i

Nodes node = list.get(i);

out.println(""+node.getNodeName()+"");

out.println("");

5. 将dtree.js 和dtree.css，jquery.js, img文件夹.放在WebRoot下面.(工程的根目录)

6.  编写我们的tree.jsp页面.
