Date Validation: Help Required

[Suresh Addagalla <su...@wipro.com>]

Hi,

I haven't been able to successfully use the Validator for doing Date
validations with struts 1.1 b3.

I need to localize the date format. Since Validator would anyway take
the default locale and the SHORT form of the date from the system, I
have decided that I will use the short format in all Locales. But I am
facing the following problems.

1. If I don't specify the "dateFormat" and/or "dateFormatStrict", I am
getting JavaScript errors (msg: length is null or not defined..) in the
2nd line in the code below (from validator-rules.xml)


                   var datePattern = oDate[x][2]("datePatternStrict");
                   if ((form[oDate[x][0]].type == 'text' ||
                        form[oDate[x][0]].type == 'textarea') &&
                       (value.length > 0) &&
                       (datePattern.length > 0)) {
                     var MONTH = "MM";
                     var DAY = "dd";
                     var YEAR = "yyyy";
                     var orderMonth = datePattern.indexOf(MONTH);
                     var orderDay = datePattern.indexOf(DAY);
                     var orderYear = datePattern.indexOf(YEAR);

2. Validator seems to be using a fixed date format (last 6 lines in the
code above). How can the JavaScript take care of other locales/formats?
Do I need to change the JavaScript per installation basis or Do I need
to download a different version of struts jar? What exactly is required
to achieve localization.

IMP: As far as possible, I would like to avoid specifying the
"dateFormat"/"dateFormatStrict" in validator-rules.xml since I want to
use the default locale's SHORT form.

Thanks,
Suresh

You cannot parse the date client side as you don't know the current locale the 
client has choosen and if you knew you couldn't find out the date pattern for 
the locale either. So you do not have pattern to match with.

Remove the javascript section from validator-rules.xml since it works only if 
you specify datePatternStrict. If you remove it, the validation will occur 
server side only. And server-side validation uses the current client locale's 
date format, afaik.

Hth,
