WML Input Fields

INPUT Tag
The <input> tag is used to collect text information that is entered by the user. It includes the following features:

• If valid, the value entered by the user will be assigned to the variable named in the mandatory name attribute.


• An invalid entry will not be accepted by the browser. Validity is based upon the input mask set by the optional format attribute. An input mask dictates which alphanumeric and punctuation characters can be entered into the input element and the order that they must be entered. The permitted values for the format attribute are as follows:
  
  

  Value	Description
  A	Any uppercase alphabetic or punctuation character
  a	Any lowercase alphabetic or punctuation character
  N	Any numeric character
  *N	Any number of any numeric characters
  X	Any uppercase character
  x	Any lowercase character
  M	Any character, but is treated as uppercase for date entry
  *M	Any number of any characters, but is treated as uppercase for date entry
  m	Any character, but is treated as lowercase for data entry
  *f	Any number of any type of characters
  nf	Any n integer number of any characters
  \c	Display the character after the slash in the display



• The default is to accept essentially any number of any type of characters.


• The emptyok attribute will permit an empty entry.


• The characters in the password string are usually displayed on the monitor as a series of asterisks. However, a password input is not secure.


• In WML, there is no equivalent to the <form> tag in HTML. However, you can use <fieldset> elements to group related input elements.
