Formatted Entry Fields

58 Genie Application Style Guide February 2001
■ Use the maxlength attribute to prevent users from losing entered data.
When the user exits a data query formatted with 3N (NNN) or 3M (MMM), the data is
lost when the user does not enter exactly 3 numbers or characters. Set the
maxlength
attribute and state the number of required number of characters in the title to inform
the user and avoid lost data.
■ The emptyok="false" attribute has no effect.
This attribute does not prevent the user from leaving an input field empty.
Mitsubishi Trium Formatted Input
Formatted text entry is similar to the Openwave browser with the following exception:
■ Always provide a short descriptive title as part of the element
This will be displayed when the user is editing the data
■ Handsets vary with their treatment of format strings
One handset type requires a format of M*m to contain at least two characters, another
type will accept a single character input with a format of Aa*a but will add a line feed
character to the data that is entered to make it two characters long.
■ The emptyok="false" attribute has no effect.
This attribute does not prevent the user from leaving an input field empty.
