import java.net.*;
import java.io.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.*;
public class Server extends JFrame implements ActionListener,KeyListener{

/**

*/
private static final long serialVersionUID = 1L;
JPanel jpl = null;
JTextArea jta = null;
JTextField jtf = null;
JScrollPane jsp =null;
JButton openButton,closeButton = null;
JLabel socketLabel = null;
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
new Server();
}
public Server(){
jpl = new JPanel();
jta = new JTextArea();
jsp = new JScrollPane(jta);
jtf = new JTextField("9988",10);
jtf.setEditable(false);//端口为只读
openButton = new JButton("开始");
openButton.addActionListener(this);//对打开按钮 添加监听操作
closeButton = new JButton("关闭");
closeButton.setEnabled(false);
socketLabel = new JLabel("监听端口");
jpl.add(socketLabel);//添加监听端口标签
jpl.add(jtf);//添加端口号
jpl.add(openButton);//添加打开按钮
jpl.add(closeButton);//关闭打开按钮
this.add(jpl,"North");
this.add(jsp,"Center");
//设置框体大小，设置可现实
this.setSize(400, 300);
this.setVisible(true);
this.setTitle("SPServerSocket");

}
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
//如果用户点击发送 信息按钮
if(e.getSource()==openButton){
jpl.remove(openButton);
jpl.validate();
jpl.repaint();
}
}
public void keyPressed(KeyEvent arg0) {
// TODO Auto-generated method stub

}
public void keyReleased(KeyEvent arg0) {
// TODO Auto-generated method stub

}
public void keyTyped(KeyEvent arg0) {
// TODO Auto-generated method stub

}
}

Answer 2

通过js事件就可以做到
在按钮的click事件中定义：
fouction click(){
然后设置按钮隐藏就可以
}

Answer 3

去除？是按钮失效 还是消失？一般可通过js控制 很简单的
<input type="button" id="bt" onclick="helll();" value="button"/>
function hello(){
document.getElementById('bt').remove();//这样就可以把按钮去除

}
