分享再次提问：不同frame间applet间通信
不同frame间的applet如何通信？
---------------
1.html
---------------
<html>
<head>
</head>
<frameset rows = "*" cols = "50%, 50%">
<frame name = "leftFrame" src = "2.html">
<frame name = "rightFrame" src = "3.html">
</frameset>
</html>
--------------
2.html
--------------
<applet name = "left" code = "Applet1.class" height = "300" width = "300">
</applet>
--------------
3.html
--------------
<applet name = "right" code = "Applet2.class" height = "300" width = "300">
</applet>
--------------
Applet1.java
--------------
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;
public class Applet1 extends Applet implements ActionListener{
public void init() {
JButton bt = new JButton("list");
add(bt);
bt.addActionListener(this);
}
public void actionPerformed(ActionEvent e) {
Enumeration ee = getAppletContext().getApplets();
while(ee.hasMoreElements()) {
System.out.println(ee.nextElement());
}
}
}
结果我按list按钮的时候，只得到：
Applet1[panel0,0,0,300x300,layout=java.awt.FlowLayout]
也就是说，这两个applet不在同一个context下？那我又该如何能使它们通信呢？
