[jQuery] How to get applet width and height in Firefox


Hi,
I was trying to get an applet width and height using jquery and have
found this problem:
<applet code="MyApplet.class" archive="HelloApllet.jar" id="MyApplet"
width="80%" height="80%">
var appletWidth = $('MyApplet').width();
and in firefox got nothing but in IE works fine
I have googled but found nothing about that.
Sombody now why it does'nt work in FF ? And how can i get applet width
in FF ?
regards
