// General Javascript/jQuery for Quick Order Portal 'Freestyle'
//--------------------------------------------------------------
/* NOTES regarding QOP Javascript enhancements
//--------------------------------------------------------------
 This Javascript is provided as is, there is no support for
 any the supplied code below.
 
 The code requires the inclusion of jQuery before this code
 is loaded.
 
 The banner fading functionality requires both jQuery, then
 the jQuery innerfade plugin.

 This file contains some useful functions including
 - Automatic smart inclusion of helper text in the login and
   search input fields. E.g. 'search' or 'login'.
 - Functions to aid Javascript that needs to target a specific
   QOP page. E.g. just the home page, or every page excluding
   the basket or checkout pages.
 - Addition of enhancing links in the mini-baskets that can
   be included as part of the design.
 - Cross-fading image slideshow functionality i.e. an
   imitation flash banner. This is both more compatible,
   generally smoother and easier to maintain.
 - Some general housekeeping e.g. the ability to switch
   global product text on the product details page and
   the addition of 'in stock' text where necessary.
 - Javascript content addition helper functions.
   E.g. extraFooterContent and extraPrimaryContent variables
   can both be edited. If present they allow the addition
   of new page content post-load.
 - Automatic footer placement in response to large product
   lists etc. This should only be used as a last resort if
   you are finding the CSS tricky.
