public class LabelDelTest extends JFrame implements ActionListener {
JLabel label;
JButton button;
public LabelDelTest() {
label = new JLabel("新建标签",JLabel.CENTER);
label.setBorder(new TitledBorder(""));
button = new JButton("删除标签");
button.addActionListener(this);
add(label,"North");

你是要隐藏吗？用jquery中的hide()行吗？
