1// ----------------------------------------------------------------------
2// Javascript form validation routines.
3// Author: Stephen Poley
4//
5// Simple routines to quickly pick up obvious typos.
6// All validation routines return true if executed by an older browser:
7// in this case validation must be left to the server.
8//
9// Update Jun 2005: discovered that reason IE wasn't setting focus was
10// due to an IE timing bug. Added 0.1 sec delay to fix.
11//
12// Update Oct 2005: minor tidy-up: unused parameter removed
13//
14// Update Jun 2006: minor improvements to variable names and layout
15// ----------------------------------------------------------------------
