Date formating global support
-----------------------------
Key: TAPESTRY-2198
URL: https://issues.apache.org/jira/browse/TAPESTRY-2198
Project: Tapestry
Issue Type: Improvement
Affects Versions: 5.0.11
Reporter: Davor Hrg
there is a javascript implementation of
SimpleDateFormat and is apache 2.0 licensed
http://www.timdown.co.uk/code/simpledateformat.php
it implements most of:
http://java.sun.com/j2se/1.5.0/docs/api/java/text/SimpleDateFormat.html
It is 8.7 Kb with stripped comments.
I'm looking at making a trimmed down version that can parse/format only numeric
date parts : day, month, year, dour, min sec.
This covers most likely usages on the client side (forms and datefield) and
would make shorter code.
(I feel that prototype is bloated already so another 10K does not look apealing)
Not to complicate things and optimize too soon, full lib can be used now,
and later along with "multiple js lib support" the short version should be made
available and pushed as default.
while talking about dates... date format should be in message catalog so it is
locale specific.
for example in my language date format is: dd.MM.yyyy
there should be different keys for server side format and client side format
(the formats should be compatible of course)
tapestry-date-format-server=MM/dd/yyyy
tapestry-date-format-js=MM/dd/yyyy
(which are sam in case we use forementioned lib)
or, if one would choose to use the former date picker i would be:
tapestry-date-format-server=MM/dd/yyyy
tapestry-date-format-js=%m.%d.%Y
I feel strongly about this being global key instead parameter for
datefield, but even if it is only for date-field there should be two formats
(server and js)
in the end... the formater should be used to test validity for the field on the
client side
or regexp added to message catalog
tapestry-date-format-js-regex=...complex or simple regex......
