/* FORM FIELDS SUMBIT CHECKER
© 2006 Analytic Soft, www.analytic.com.ua
--------------------------------------------------------------------------------------
Description

STEP1. First form fileds should be registered.
registerFieldChecking([field_name], [check_type], [message], [param1], [param2])
!!!One field CAN be registered twice or more with different value of [check_type]

STEP2. When user submits form we call testFormBeforeSubmit()
--------------------------------------------------------------------------------------
FUNCTION registerFieldChecking([field_name], [check_type], [message], [param1], [param2])
PARAMETERS:
1. [field_name]: input, textarea, checkbox, radiobutton tag attribute NAME
2. [check_type]:
'NOT_EMPTY'  - checks field for not empty.
'MIN_LENGTH' - checks field for minimal length. [param1] is the minimal allowed length.
'MAX_LENGTH' - checks field for minimal length. [param1] is the maximal allowed length.
'EMAIL'      - checks field to be email.
'REGEXP'     - checks field with regexp.
3. [message] - message for alert.
4. [param2]  - reserved.

EXAMPLES:
      registerFieldChecking('NameTxt', 'NOT_EMPTY','??? ??? ?? ?????? ?????','','');
	  registerFieldChecking('NameTxt', 'MIN_LENGTH','??? ???? ?? ???????? ???????? ??? ???????? ??????','3','');
