Hello,
Apparently using the MAYSCRIPT param in the Applet HTML tag you can allow the Applet to use JavaScript. I was wondering how to go about doing this.
I want to be able to close the browser window from within the applet and using JavaScript seems like a good way.
Thanks,
Adam

Hi aj72886,

You can call an applet method from javascript, for example :
<html><body>
<applet code="MaClasse.class" name="my"></applet>
<form>
<input type=button value="Call Javascript"  
       onclick="if (my) {my.callJavascript();}">
</form>
</body></html>
the javascript code call a method named "callJavascript".

And calling javascript from a java applet is browser specific. For Netscape :

import netscape.javascript.JSObject;

...
   try
      {
      JSObject win = JSObject.getWindow(this);
      win.eval("alert('javascript called');");  // <-- javascript code
      }
    catch (Exception e)
      {
      System.out.println("Exception:Javascript");
      e.printStackTrace();
       }
