Javascript Remove comma from form input

I have a form element, <INPUT id=aircraftcost name=aircraftcost>

Is it possible to write a javascript that upon submit removes any comma from the field?

Can someone show me what I need to insert into the page to do this?

Because some of the older IE browsers don't support all of javascript.  But it might be IE6 not IE7 that it is an issue.  Anyway I found a solution, tested it in IE7 using spoon, and everything is good now.  Thanks.

RegExp as argument to replace is supported by IE6 too
