html中onclick事件,javascript中window.open("页面路径+名称");
javaswing给你个例子,如下:
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class TanChuShiJian extends JFrame implements ActionListener {
public TanChuShiJian() {
// TODO Auto-generated constructor stub
Container c = getContentPane();
c.setLayout(null);
JButton b = new JButton("测试");
b.addActionListener(this); //为按钮添加事件
b.setBounds(10, 10, 150, 30);
c.add(b);
setSize(400, 400);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
if("测试".equals(e.getActionCommand())) {
System.out.println("1111111111");
new NewFrame();
}
}
public static void main(String[] args) {
new TanChuShiJian();
}
}
class NewFrame extends JFrame {
public NewFrame() {
// TODO Auto-generated constructor stub
Container c = getContentPane();
JPanel p = new JPanel();
p.add(new JLabel("我是新窗口!"));
c.add(p);
setSize(200, 300);
setVisible(true);
}
}
