New windows when click on a link in note field

New windows when click on a link in note field

I have this note field with a link which I want to make it as a popup or a new windows.

When I tried to do this in the source mode for the note field and click save:

  1. <a href="some_link_here" onClick="MyWindow=window.open('','MyWindow','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=720,height=480'); return false;">PLACE_YOUR_LINKTEXT_HERE</a>
everything from the onClick is removed and become like this
  1. <a href="some_link_here">PLACE_YOUR_LINKTEXT_HERE</a>
Is this suppose to be like that? If this is not supported is there a way around it?

Also, is there a way to embed HTML or iFrame in the form?
