Applet and the JavaScript
|
|
|
| Hi All,
I am  . Given the two codings below:
the Applet and the JavaScript, is it correct to say that
the Applet is calling the Javascript or the Javascript is
calling the Applet?
Your help is appreciated.
bH
import java.applet.*;
import java.net.*;
public class inJava extends Applet{
public void init(){
String msg1 = "We will jump to an HTML tag";
String msg2 =
"http://www.extension.iastate.edu/gif/Balls/l_green.gif";
try {
getAppletContext().showDocument
(new URL("javascript:doAlert(\"" + msg1 +"\")"));
getAppletContext().showDocument
(new URL("javascript:jumpTo(\"" + msg2 +"\")"));
}
catch (MalformedURLException me) { }
}
}
<HTML><HEAD></HEAD><BODY>
<SCRIPT>
function doAlert(s) {
alert(s);
}
function jumpTo(tag) {
self.location=tag;
}
</SCRIPT>
<APPLET CODE="inJava.class"
NAME="myApplet" MAYSCRIPT
HEIGHT=400 WIDTH=100>
</APPLET>
<P>
<A NAME="JUMP">jump here from JAVA via JAVASCRIPT</A>
</BODY>
</HTML>

I didn't test this--I'm assuming it works for you. I don't see any place
where JavaScript calls the applet--the applet is simply embedded in the HTML
The applet could loosely be said to be calling JavaScript, although it is
through the applet context, the browser and the browser's ability to execute
the javascript protocol in a URL. Not all browsers (or all versions of all
browsers) support showDocument, even fewer will handle JavaScript in a URL
and those that remain may be subject to popup blocking.
