Step 1: we need to prepare this js file before we start. The code is as follows. I'll call it tree.js.
I'm not going to go into the details here because the code is so long, but OK as long as we know how to use it. Like pork we can eat on OK, not 1 must know how to raise a pig.
Step 2: create the database. The code to create the database is as follows.
create database `treedemo`;
use treedemo;
create table trees(
tid int primary key not null,
pid int not null,
tname varchar(50) not null,
isleaf int
);
select * from trees;
insert into trees(tid,pid,tname)values(0,-1,' organizational content ');
insert into trees(tid,pid,tname)values(1,0,' SMS ');
insert into trees(tid,pid,tname)values(2,0,' MMS ');
insert into trees(tid,pid,tname)values(3,0,' news ');
insert into trees(tid,pid,tname)values(4,1,' mobile living ');
insert into trees(tid,pid,tname)values(5,1,' single scroll vod ');
insert into trees(tid,pid,tname)values(6,2,' custom ');
insert into trees(tid,pid,tname)values(7,2,' on demand ');
insert into trees(tid,pid,tname)values(8,3,' property channel ');
insert into trees(tid,pid,tname)values(9,3,' rural channels ');
insert into trees(tid,pid,tname)values(10,3,' digital channel ');
insert into trees(tid,pid,tname)values(11,6,' humorous jokes ');
insert into trees(tid,pid,tname)values(12,7,' ringtones ');
insert into trees(tid,pid,tname)values(13,7,' greeting CARDS ');
insert into trees(tid,pid,tname)values(14,7,' animation ');
insert into trees(tid,pid,tname)values(15,13,' greeting card 1');
insert into trees(tid,pid,tname)values(16,13,' greeting card 2');
insert into trees(tid,pid,tname)values(17,13,' greeting card 3');
insert into trees(tid,pid,tname)values(18,13,' greeting card 4');
select * from trees;
Description of table fields:
(1) tid represents the number of the node;
(2) the number of the parent node of pid;
(3) name of tname node;
(4) isleaf indicates whether the node is a leaf node, leaf node is 1, and non-leaf node is 0. This field can be added or deleted according to the actual situation.
Step 3: create an WEB project in myeclipse and name it "TreeDemo". Create the js folder, css folder and images folder under the WebRoot folder to hold.js files,.css files and image files used in the project, respectively.
Step 4: write the database connection class, where the user name and password need to be changed according to your database, the code is as follows.
Step 5: write the javabean class as follows,
Step 6: create the relevant DAO class, as follows. The DAO class saves the database table set into the Vector object.
Step 7: display the tree on the page. Create the show_tree.jsp page in TreeDemo, as follows.
Step 8: create a frame page, index.html code as follows, and list_default.htm.
Step 9: run effect

I'm not going to go into the details here because the code is so long, but OK as long as we know how to use it. Like pork we can eat on OK, not 1 must know how to raise a pig.
Step 2: create the database. The code to create the database is as follows.
create database `treedemo`;
use treedemo;
create table trees(
tid int primary key not null,
pid int not null,
tname varchar(50) not null,
isleaf int
);
select * from trees;
insert into trees(tid,pid,tname)values(0,-1,' organizational content ');
insert into trees(tid,pid,tname)values(1,0,' SMS ');
insert into trees(tid,pid,tname)values(2,0,' MMS ');
insert into trees(tid,pid,tname)values(3,0,' news ');
insert into trees(tid,pid,tname)values(4,1,' mobile living ');
insert into trees(tid,pid,tname)values(5,1,' single scroll vod ');
insert into trees(tid,pid,tname)values(6,2,' custom ');
insert into trees(tid,pid,tname)values(7,2,' on demand ');
insert into trees(tid,pid,tname)values(8,3,' property channel ');
insert into trees(tid,pid,tname)values(9,3,' rural channels ');
insert into trees(tid,pid,tname)values(10,3,' digital channel ');
insert into trees(tid,pid,tname)values(11,6,' humorous jokes ');
insert into trees(tid,pid,tname)values(12,7,' ringtones ');
insert into trees(tid,pid,tname)values(13,7,' greeting CARDS ');
insert into trees(tid,pid,tname)values(14,7,' animation ');
insert into trees(tid,pid,tname)values(15,13,' greeting card 1');
insert into trees(tid,pid,tname)values(16,13,' greeting card 2');
insert into trees(tid,pid,tname)values(17,13,' greeting card 3');
insert into trees(tid,pid,tname)values(18,13,' greeting card 4');
select * from trees;
Description of table fields:
(1) tid represents the number of the node;
(2) the number of the parent node of pid;
(3) name of tname node;
(4) isleaf indicates whether the node is a leaf node, leaf node is 1, and non-leaf node is 0. This field can be added or deleted according to the actual situation.
Step 3: create an WEB project in myeclipse and name it "TreeDemo". Create the js folder, css folder and images folder under the WebRoot folder to hold.js files,.css files and image files used in the project, respectively.
Step 4: write the database connection class, where the user name and password need to be changed according to your database, the code is as follows.
package com.sx.mas.utils;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DBConn {
private static final String DRIVER="com.mysql.jdbc.Driver";
private static final String URL="jdbc:mysql://localhost:3306/treedemo";
Connection conn=null;
public Connection getConnection(){
try {
Class.forName(DRIVER);
conn=DriverManager.getConnection(URL,"root","root");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return conn;
}
}
package com.sx.mas.utils;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DBConn {
private static final String DRIVER="com.mysql.jdbc.Driver";
private static final String URL="jdbc:mysql://localhost:3306/treedemo";
Connection conn=null;
public Connection getConnection(){
try {
Class.forName(DRIVER);
conn=DriverManager.getConnection(URL,"root","root");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return conn;
}
}
Step 5: write the javabean class as follows,
package com.sx.mas.beans;
public class TreeNode {
private int tid;
private int pid;
private String tname;
private int isleaf;
public int getTid() {
return tid;
}
public void setTid(int tid) {
this.tid = tid;
}
public int getPid() {
return pid;
}
public void setPid(int pid) {
this.pid = pid;
}
public String getTname() {
return tname;
}
public void setTname(String tname) {
this.tname = tname;
}
public int getIsleaf() {
return isleaf;
}
public void setIsleaf(int isleaf) {
this.isleaf = isleaf;
}
}
package com.sx.mas.beans;
public class TreeNode {
private int tid;
private int pid;
private String tname;
private int isleaf;
public int getTid() {
return tid;
}
public void setTid(int tid) {
this.tid = tid;
}
public int getPid() {
return pid;
}
public void setPid(int pid) {
this.pid = pid;
}
public String getTname() {
return tname;
}
public void setTname(String tname) {
this.tname = tname;
}
public int getIsleaf() {
return isleaf;
}
public void setIsleaf(int isleaf) {
this.isleaf = isleaf;
}
}
Step 6: create the relevant DAO class, as follows. The DAO class saves the database table set into the Vector object.
package com.sx.mas.beans;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Vector;
import com.sx.mas.utils.DBConn;
public class TreeDAO {
public Vector getTree(){
Vector vec = new Vector();
DBConn dbconn = new DBConn();
Connection conn = dbconn.getConnection();
try {
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from trees");
while(rs.next()){
TreeNode treenode = new TreeNode();
treenode.setTid(rs.getInt("tid"));
treenode.setPid(rs.getInt("pid"));
treenode.setTname(rs.getString("tname"));
treenode.setIsleaf(rs.getInt("isleaf"));
vec.add(treenode);
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return vec;
}
}
package com.sx.mas.beans;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Vector;
import com.sx.mas.utils.DBConn;
public class TreeDAO {
public Vector getTree(){
Vector vec = new Vector();
DBConn dbconn = new DBConn();
Connection conn = dbconn.getConnection();
try {
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from trees");
while(rs.next()){
TreeNode treenode = new TreeNode();
treenode.setTid(rs.getInt("tid"));
treenode.setPid(rs.getInt("pid"));
treenode.setTname(rs.getString("tname"));
treenode.setIsleaf(rs.getInt("isleaf"));
vec.add(treenode);
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return vec;
}
}
Step 7: display the tree on the page. Create the show_tree.jsp page in TreeDemo, as follows.
<%@ page language="java" import="java.util.*" contentType="text/html; charset=gb2312"%>
<%@ page import="com.sx.mas.beans.*" %>
