Passing parameters to a Java applet from JavaScript

Posted on 1998-10-20

Last Modified: 2008-03-03
Does anyone know how can I pass parameters to a Java applet on a web page using JavaScript's onclick that calls a function.

I want to be able to pass different parameters to the applet every time a button has been clicked etc.

Any ideas?

By the way. I'm using Netscape 3 under Win95.

<APPLET NAME="myApplet"....>

<INPUT TYPE="BUTTON" VALUE="javafunction1" onClick="document.myApplet.javafunction1()">
<INPUT TYPE="BUTTON" VALUE="javafunction2" onClick="document.myApplet.javafunction2()">

The functions need to be public and the applet needs to have been loaded first... NS3 is finicky about reloading applets at resize though so be careful...

Good one Michel, but...

I know how to invoke methods that are already defined inside the applet and do things.

My question was:

If I have an applet like this...

<applet code="paramtst" name="appletBig"
    width="266" height="150">
        <param name="someNumber" value="12346">
        <param name="someText" value="Whats up Doc?!">

How do I pass a parameter to "someNumber" using onclick ?

I would think

but I am not 100% sure on this. Since the parameters are normally read in the init() method, wouldn't it be safer to do a
and have a public function to change the parameters.

Do you by any chance have a/some URL/s handy that use the above implementation?

The implementation is pretty straight forward but have a closer look at Live Wire at http://devedge.netscape.com
