Cookie-based SoppingCart script v.2.0.1
by Matevosyan Artem (zverek@nm.ru)
Usage:
Dynamic text string:
Version 2.xx history:
^2.0.1
+ add "don't ask" feature to clear method; call cart.clear(1); to void confirmation;
^2.0
+ Release
* Moved to object oriented style
* Fixed using '&' and '|' in args problem
Version 1.xx history
^1.05
* Fixed some bugs in clearCart() finction
+ Added cookie exiration date
^1.04
* Added confirm dialog to deleting an item from cart
* Commented getCookie function deleted
* Optimized add2cart function: precisely the statement determining the item existance. If the
item already ordered?
^1.03
* Fixed getCookie function. There was an error getting the cookie text. Therefore the algorithm
was replaced by another one using regexp to locate the cookie. The old getCookie function
commented. Anyway it doesn't work :)
* Multi argumential add2cart function, you can now provide additional arguments
to your cart. In addition to id, name, price and quantity you may use i.e. description
or picture id. This information also will be saved in cookie. The only condition of using
additional args is they can not contain '&' or '|' as this will ruin the cookie structure
^1.02
+ CountGoods function showing the number of goods in shopping cart
+ Usage script respective to russian literal count bendings
* Fixed getCookie(): added no cookie defined case
^1.01
+ Editing goods quantity support
+ Delting goods support
^1.00
+ Release

# The checkCookieSupport() function doesn't work
