The following javascript code gives me the date validation that I need
except
after the correct date is entered into the field, it puts the date in
the wrong format
EXAMPLE: User enters 2/14/2006 and it shows in the field Feb 14 2006
after the onBlur
I want it to leave the formatting of the date in the field as 2/14/2006
and not change the input to Feb 14 2006
I am very new to javascript and I don't know what to take out in the
following code to accomplish what I need. Can Anyone HELP? Thanks so
much
