Formula URL or Formula Text Button that will perform an action, without the need to navigate away from the current dashboard/report/record?

I know that this will work, but the button will be grey.  I'm not sure that I have working code  to easily post to get the jgrowl to work as a Vibrant colored button.



var text URL = URLRoot() & "db/" & "?act=API_EditRecord&_fid_80=1&rid=" & [Record ID#];

"javascript:" &
"$.get('" & 
$url & 
"',function(){" &
"$.jGrowl('This Item has been put on PO CANCEL snooze', {life: 5000, theme: 'jGrowl-green'});" &
"});" &
"void(0);
