* ---------------------------------------------------------------------------------------------
* displays an alert window with error conditions, sets 'document.returnValue' to true or false.
* ---------------------------------------------------------------------------------------------
*  Summary of javascript calls:
* 
*  Function: creditcard
*  Purpose:
*   Check valid credit cards entries:
*   1234-123456-12345   for American Express
*   1234-1234-1234-1234 for Discover/MC/Visa
* 
*  Also allows space and dots or all numbers with no seperators.
* --------------------------------------------------------------------
*  Function: isfloat
*  Purpose:
*   check and format the input into a floating point value.
*
*   The number of decimal places requested is the argument to the call.
*
*  Example:
*   isfloat.2
* --------------------------------------------------------------------
*  Function: datecheck
*  Purpose:
*   check a date format. some formatting of the date may occur, you may want to
*   pre process with 'notnull' and postprocess with 'capfirst'
*
*  current supported format checks:
*   1  === Mon-DD-YYYY (also accepts Mon-D-YYYY, but formats back to Mon-DD-YYYY)
*   1n === same checkas 1, but allows 'never' as an input as well.
*
*  Example:

* --------------------------------------------------------------------
*  Function: trim
*  Purpose:
*   strip off leading/trailing writespace from value.
*
*  Example:

*
*  Example:
*   lowercase
* --------------------------------------------------------------------
*  Function: uppercase
*  Purpose:

*
*  Example:
*   uppercase
* --------------------------------------------------------------------
*  Function: capfirst
*  Purpose:
*   Convert the first character of every word to capital letter. If ".L"
*   follows the call, all other characters in the string are converted to lower case.
*
*  Example:
*   capfirst.L
* --------------------------------------------------------------------
*  Function: emailaddress
*  Purpose:
*   Javascript to check syntax of email address. If no email given, and varags "N"
*  specified, no check.
*  Example:
*    emailaddress.N      (field can be null without error)
*  or
*    emailaddress
* --------------------------------------------------------------------
*  Function: inrange
*  Purpose:
*   Check field is numerically within a range specified.
* 
*  Example call:
*     inrange.low-high
*     inrange.4-999
* --------------------------------------------------------------------
*  Function: isalpha
*  Purpose:
*   Checks that "field" only contains a-zA-Z values. the following characters
*   can be added to the call following a "." character to:
*    S: allows spaces too.
*    D: allows dots too.
*    A: allows apostrophes too.
*    C: allows commas too.
*    U: allows underscores too.
* 
*  Example call:
*     isalpha.D
*     isalpha.SD
*     isalpha.DUS
* --------------------------------------------------------------------
*  Function: isalphanumeric
*  Purpose:
*   Checks that "field" only contains a-zA-Z0-9 values. the following characters
*   can be added to the call following a "." character to:
*    S: allows spaces too.
*    D: allows dots too.
*    A: allows apostrophes too.
*    C: allows commas too.
*    @: allows the @ char too.
*    d: allows the - (dash) char too.
*    U: allows the _ (underscore) char too.
*    s: allows the / (slash) char too.
*    b: allows the \ (back-slash) char too.
* 
*  Example call:
*     isalphanumeric
*     isalphanumeric.DSA
*     isalphanumeric.S
*     isalphanumeric.SdU
* --------------------------------------------------------------------
*  Function: default
*  Purpose:
*  provides a client-side default for a field left empty by the visitor.
*  is subtley different than a server side default, helps to handle the
*  null value situation. This check does not cause an error notice, for
*  that, the third argument of the set is ignored, but must still be passed.
* 
*  Example call:
*   'default.default value goes here'
* or 
*   'default.default+value+goes+here'
* --------------------------------------------------------------------
*  Function: maxlength
*  Purpose:
*   Checks a maximum length of "field". The length to check against is
*  sent via the "jscall.X" value.
* --------------------------------------------------------------------
*  Function: minlength
*  Purpose:
*   Checks a minimum length of "field". The length to check against is
*  sent via the "jscall.X" value. If jscall ends with "N", Null is okay
*  too.
* 
*  Example call:
*   minlength.n
*   minlength.2
*   minlength.2N
* --------------------------------------------------------------------
*  Function: minmax
*  Purpose:
*   Check field length between min/max number of characters.
*  Example:
*   minmax.min-max
*   minman.2-20
* --------------------------------------------------------------------
*  Function: notnull
*  Purpose:
*  checks that field contains a value.
* --------------------------------------------------------------------
*  Function: nullradioselect
*  Purpose:
*   Javascript to check that at least one radio button is selected.
* --------------------------------------------------------------------
*  Function: nullselection
*  Purpose:
*   Ensure a selection is picked of a "<SELECT " tag. By rule, always the
*   first element of a selection box is invalid, this is the check to perform.
* --------------------------------------------------------------------
*  Function: override
*  Purpose:
*   Used with an "<INPUT type=submit" tag to bypass the Javascript onSubmit checks,
*   letting the server-side perform any procedure defining, for example, a cancel operation.
*   For this function to work properly, the "onClick='document.override=1'" must be added to the
*   <INPUT tag. It only makes sense to have the "override" operation be the
*   first of any javascript checks to perform.
* --------------------------------------------------------------------
*  Function: phone
*  Purpose:
*   Check phone number syntax. To perform various 
*  formats, the particular check is identified via the "jscall.XYZ"
*  value.
* 
*  Where "X" may be one of:
*    1 == United States syntax
*    2 == European syntax
*    A == both 1 and 2 are ok.
* 
*  Where "Y" refers to the form for the phone number:
*    N == not required
*    R == required
* 
*  Where "Z" refers to the area code and may be one of: (applies to #1 syntax)
*    A == must have area code
*    a == are code is optional
* 
*  United States syntax is in the formats:
*        123-123-1234
*            123-1234
*
*  European syntax:
*        52 833 217 62 69
* 
*  Also allows space and dots or all numbers with no seperators.
* --------------------------------------------------------------------
*  Function: state
*  Purpose:
*  Check that a valid state was entered. Takes the first four characters
*  and checks them against the array of valid states, then abbreviates it.
*  field.value is replaced with 2-character state abbrev.
* --------------------------------------------------------------------
*  Function: touppercase
*  Purpose:
*  Makes the value in the form field Uppercase. 
* --------------------------------------------------------------------
*  Function: zip
*  Purpose:
*  Javascript to check for a valid US zip code with or without a speed zipcode.
* --------------------------------------------------------------------
*  Function: validipaddr
*  Purpose:
*  Checks that "field" only values 0-255 and dots, in a 4 octet value.
*  example: 10.10.10.10
* --------------------------------------------------------------------
*  Function: validurl
*  Purpose:
*  Checks that "field" only contains a-zA-Z0-9 values and a ".", used to check
*  "URL" entries.
* --------------------------------------------------------------------
*  Function: confirm
*  Purpose:
*  Confirms that user input in another field is identical to itself. (password -
*  confirm password) 
* 
*  Example call, the name of the input field to compare against follows the
*  "confirm." string in "jscall".
*   confirm.document.formname.object  (no layers)
*   confirm.T1.doc.formname.object   (with layers)
* --------------------------------------------------------------------
*  Function: ilt (also: ilteq, igt, and igteq)
*  Purpose:
*  perform a mathematical INTEGER compare of own value against another, error if >=(ilt),
*  >(ilteq), <=(igt) or <(igteq).
* 
*  Example call, the name of the opposite input field to compare against follows the
*  "ilt." string in "jscall".
*   ilt.document.formname.object  (no layers)
*   ilt.T1.doc.formname.object   (with layers)
*
* Note: field.value will be reset to an integer value, a float will converted to integer.
