You can attach the behavior to your link on a popup page:
<a href="javascript: self.opener.location = 'http://somewhere.ltd/path/to/dir'; self.close();">
Let go Somewhere
</a>
In addition, I recommend that you use Javascript in an unobtrusive way instead of the simple line above.
About this operation "Fade"; You cannot do this in the OS window using Javascript (no matter what).
: id theChildForm jQuery:
$("#theChildForm").submit(function() {
self.opener.location = 'http://somewhere.ltd/path/to/dir';
self.close();
});
