Java Script - Java Applet Communication - Live Connect
Here is an example of how to communicate with Java Applet using Java Script (vice-versa)
//--------------------------------TestApplet.java------------------------------------------------
import netscape.javascript.*;
import java.applet.*;
import java.awt.*;
import java.awt.HeadlessException;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;import javax.swing.JApplet;
public class TestApplet extends JApplet implements ActionListener
{
public String displayString = "India";public TestApplet() throws HeadlessException
{
super();
}public void init()
{
}public void paint(Graphics g)
{
g.drawString("Hello world! " + displayString, 50, 25);
}public void actionPerformed(ActionEvent arg0)
{}
public void ChangeText(String input)
{
try
{
displayString = input;
repaint();
System.out.println("screen refresh done");
//call the java script function with the parameter list...
JSObject win = JSObject.getWindow(this);
//Parameter List...
String args2[] = { "" };
//Function Call
win.call("testForm", args2);
}
catch (Exception e)
{
e.printStackTrace();
}
}}
//--------------------------------Test.html------------------------------------------------
<html>
<head>
<title>HTML Page</title>
<SCRIPT>
function testForm()
{
alert("Call from Java Applet - Now the form is being submited");
document.forms[0].submit();
}
</SCRIPT>
</head>
<body bgcolor="#FFFFFF">
<form method=post action=go.asp>
<APPLET CODE="TestApplet.class" NAME="muthuapplet" WIDTH=150 HEIGHT=175></APPLET>
<hr>
<A HREF="#" onClick="javascript:document.applets.muthuapplet.ChangeText('Europe');">Change</A><BR>
</form>
</body>
</html>
