How to make Infopath and javascript work together - trick

Put the InfoPath form on web page and add a content edit web part with JavaScript file.

The issue for us was we couldn't enable the JavaScript within the infoPath form because we had to enable service on our production farm and we were concern about impacting other sites.  This was an easy workaround.

There are limitations to this solutions.
The form will time out after 30 minutes and you can't control the time out.  This particular form will not be open for an extended period of time so this works perfectly for us.
