Copyright (c) Aug 2002 AAA Auto Club South Inc. MODIFICATION HISTORY ****************************************************************************** 9-27-02 Rob Plates: Made modifications to the time entry no not force a leading zero in the hour portion of the time processing. 11-15-02 Rob Plates added currency handling code 12-16-02 Rob Plates added function to handle numeric codes key entry 12-23-02 Rob Plates added Alpha UCase event handler function 02-05-03 Rob Plates allowed minus (char 45) in currency on keypress 02-14-03 Rob Plates the was a problem validating a date "05/08/03". In debugging this I found that the Day portion was the problem. It seems the parseInt() function's optional second parameter (radix) defaults to octal. Thus the result of parseInt("08") results in 0. to correct this you must use parseInt("08", 10) specifying the radix as decimal and the result is 8. In the date_validate() function I am adding this second parameter to all parseInt calls 03-20-03 Rob Plates added date and time assist functions 03-26-03 Rob Plates Added functionality to currency_sformat to deal with rounding up 9's this and currency_format required a more mathematical solution than a Logical one (as prevously done) Ileft the old code in comments in case we have to re-examine this routine 04-14-03 Rob Plates Imporved Time and Date Assist functions to erase a "full" field. ITEM #1 time_onkeypress_assist ITEM #2 date_onkeypress_assist 04-17-03 Rob Plates Added Function: decimal_onkeypress() 04-22-03 Rob Plates Added Phone Number Formatting 04-23-03 Rob Plates Added String version for Phone Strip Formatting 05-06-03 Rob PLates Added Phone String Formatting 05-25-03 Rob Plates Format Currency had some problems formatting negative currencies. Fixed the Problem added code to deal with negative numbers is currency_sformat and currency_format 05-27-03 Rob Plates Format Currency still had problems becuase we used JavaScript "MATH". If you add 1 + 0.14 the result is 1.14000000000001. Thus after we do the rounding we still need to insure that only 2 decimal places a the result. Thus this change was made. 10-23-03 Rob Plates Added alpha_numeric_onkeypress function Added alpha_only_ucase_onkeypress function Added email_onkeypress function Added email_validate function Added credit card validation functions. 11-19-03 In testing my web page I found that we could have more than one period character (my email address for example) ITEM #1 email_validate: changed the else condition to allow more than one dot char in the string just not consequetively 02-16-04 Added: alpha_ucase_numeric_onkeypress() for International Zip Codes. ******************************************************************************/ /********************************************************************************************************* Function: date_onkeypress Description: Basic function that eliminates keystrokes in appropriate for date entry.
