RE: Date parsing

2005-03-08 Thread George Sexton 
I wrote my own date handling class, and it will do what you are looking for:

Essentially, to provide a picture for the users you pass in the locale to
SaneDate.getDateFormat().

To parse the date, 

try {
new SaneDate(request.getParameter(parm),lc);
} catch (InvalidDateException ide) {
}

 I have an object with a TimeStamp member.  This will be populated by
 users of a website and entered into a database.
  
 My problem is, I would like to allow the users to enter the date in a
 number of formats.  Does anyone have any recommendations aside from
 multiple try catch blocks each trying to parse the given date with a
 different expected format?
  
 Thanks you for any help,

This has a bunch of useful methods in it.  Thank you.

However what I am looking for is some class that can handle a date/time
string in many different formats and return a date/time object back to
me.  I tried your code with 3/1/2005 and it worked fine.  3-1-2005 did
not.  This probably means that locale change is required.  Also I tried
3/1/2005 11:45 am, and that failed as well.  I am assuming this code was
not meant to handle time as well as the date portion.

Am I using your code incorrectly, or should I be looking at some other
code?

Thank You
Charles

RE: Date parsing

2005-03-08 Thread George Sexton 
Well because of the ambiguities you have to have some expectation of what
format the date will be in.

What date is 05/12/2005? In the US its May 12th. In Britain it's December
5th. You have to have some expectation and validate against it. 

The software is designed to use a Locale as an aid to parsing to set up the
expectation. In our software, we use the browser's accept-language to
retreive a locale.

The class as designed doesn't handle times. It's strictly a date class. Im
thinking about writing a date/time class, but haven't yet.

RE: Date parsing

2005-03-07 Thread Derrick Koes 

You could do regular expression field validation.  That is, client-side 
(javascript), build a regular expression object that finds a match for many 
formats and run the test function on the input string.  If true, a match was 
found, and hence a legal date.  The downside is that if you have many date 
formats, your regular expression could get pretty ugly.  Here's the appropriate 
documentation for IE jscript.
