Dtree+Jquery动态生成树节点.
最近有朋友问我一个动态生成树怎么做.后来就用Dtree js组件和Jquery实现了一个demo给他.现在贴出来给初学者做些参考.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
<link href="/jingjindatabase/pub/css/a.css" rel="stylesheet" type="text/css" />
<link href="/jingjindatabase/pub/css/dtree.css" rel="stylesheet" type="text/css" />
<link href="/jingjindatabase/pub/css/a.css" rel="stylesheet" type="text/css" /> <link href="/jingjindatabase/pub/css/dtree.css" rel="stylesheet" type="text/css" />
4：页面代码书写的位置是：一般写在表格的td之中
Javascript代码
<script type="text/javascript" src="/myMobanGis/pub/js/dtree.js"></script>
<script type="text/javascript">
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);
</script>
<script type="text/javascript" src="/myMobanGis/pub/js/dtree.js"></script>
<script type="text/javascript">
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("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);
</script>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
1:dtree.css

</html>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
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
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
package com.dao;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
public class DaoTest {
Connection con = null;
public Connection getConnection() {
Connection conn = null;
String url = "jdbc:mysql://localhost/test?useUnicode=true&characterEncoding=gbk";
String user = "root";
String password = "admin";
try {
if (conn == null) {
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection(url, user, password);
}
} catch (Exception e) {
System.out.println("连接失败");
return null;
} finally {
url = null;
user = null;
password = null;
}
return conn;
}
public ArrayList<Nodes> getNodeInfo() {
String sql = "select nodeId ,parentId ,hrefAddress ,nodeName from tree_table order by id ";
PreparedStatement pre = null;
Connection conn = null;
conn = getConnection();
ResultSet rs = null;
ArrayList<Nodes> list = new ArrayList<Nodes>();
try {
pre = conn.prepareStatement(sql);
rs =pre.executeQuery();
while (rs.next()){
Nodes node = new Nodes();
node.setHrefAddress(rs.getString("hrefAddress"));
node.setNodeId(rs.getString("nodeId"));
node.setParentId(rs.getString("parentId"));
node.setNodeName(rs.getString("nodeName"));
list.add(node);
}
rs.close();
pre.close();
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}finally{
pre = null;
conn = null;
rs = null;
}
return list;
}
}
package com.dao;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
public class DaoTest {
Connection con = null;
public Connection getConnection() {
Connection conn = null;
String url = "jdbc:mysql://localhost/test?useUnicode=true&characterEncoding=gbk";
String user = "root";
String password = "admin";
try {
if (conn == null) {
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection(url, user, password);
}
} catch (Exception e) {
System.out.println("连接失败");
return null;
} finally {
url = null;
user = null;
password = null;
}
return conn;
}
public ArrayList<Nodes> getNodeInfo() {
String sql = "select nodeId ,parentId ,hrefAddress ,nodeName from tree_table order by id ";
PreparedStatement pre = null;
Connection conn = null;
conn = getConnection();
ResultSet rs = null;
ArrayList<Nodes> list = new ArrayList<Nodes>();
try {
pre = conn.prepareStatement(sql);
rs =pre.executeQuery();
while (rs.next()){
Nodes node = new Nodes();
node.setHrefAddress(rs.getString("hrefAddress"));
node.setNodeId(rs.getString("nodeId"));
node.setParentId(rs.getString("parentId"));
node.setNodeName(rs.getString("nodeName"));
list.add(node);
}
rs.close();
pre.close();
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}finally{
pre = null;
conn = null;
rs = null;
}
return list;
}
}3. 节点。JAVABEAN.类.
Java代码
package com.dao;
public class Nodes {
private int id;
private String nodeId;
private String parentId;
private String hrefAddress;
private String nodeName;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getNodeId() {
return nodeId;
}
public void setNodeId(String nodeId) {
this.nodeId = nodeId;
}
public String getParentId() {
return parentId;
}
public void setParentId(String parentId) {
this.parentId = parentId;
}
public String getHrefAddress() {
return hrefAddress;
}
public void setHrefAddress(String hrefAddress) {
this.hrefAddress = hrefAddress;
}
public String getNodeName() {
return nodeName;
}
public void setNodeName(String nodeName) {
this.nodeName = nodeName;
}
}
package com.dao;
public class Nodes {
private int id;
private String nodeId;
private String parentId;
private String hrefAddress;
private String nodeName;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getNodeId() {
return nodeId;
}
public void setNodeId(String nodeId) {
this.nodeId = nodeId;
}
public String getParentId() {
return parentId;
}
public void setParentId(String parentId) {
this.parentId = parentId;
}
public String getHrefAddress() {
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");
Java代码
package com.handler;
import java.io.IOException;
import java.io.PrintWriter;
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<Nodes> list= test.getNodeInfo();
if(list!=null&&list.size()>0){
out.println("<?xml version=/"1.0/" encoding=/"UTF-8/"?>");
out.println("<nodes>");
for(int i=0;i<list.size();i++){
Nodes node = list.get(i);
out.println("<node nodeId='"+node.getNodeId()+"' parentId='"+node.getParentId()+"' hrefAddress='"+node.getHrefAddress()+"'>"+node.getNodeName()+"</node>");
}
out.println("</nodes>");
}
}
}
package com.handler;
import java.io.IOException;
import java.io.PrintWriter;
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<Nodes> list= test.getNodeInfo();
if(list!=null&&list.size()>0){
out.println("<?xml version=/"1.0/" encoding=/"UTF-8/"?>");
out.println("<nodes>");
for(int i=0;i<list.size();i++){
Nodes node = list.get(i);
out.println("<node nodeId='"+node.getNodeId()+"' parentId='"+node.getParentId()+"' hrefAddress='"+node.getHrefAddress()+"'>"+node.getNodeName()+"</node>");
}
out.println("</nodes>");
}
}
}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.
