TYPE
Defines the type of data the field accepts. Defaults to free text. Several
types of fields can be defined with the type attribute:
- CHECKBOX
-
Used for simple Boolean attributes, or for attributes that
can take multiple values at the same time. The latter is represented by a
number of checkbox fields each of which has the same NAME. Each
selected checkbox generates a separate name/value pair in the submitted
data, even if this results in duplicate names. The default VALUE for
checkboxes is ON.
- HIDDEN
-
No field is presented to the user, but the content of the field is
sent with the submitted form. This value may be used to transmit state
information about client/server interaction.
- IMAGE
-
An image field upon which you can click with a pointing device, causing
the form to be immediately submitted. The coordinates of the selected
point are measured in pixel units from the upper left corner of the
image, and are returned (along with the other contents of the form) in
two name/value pairs. The x-coordinate is submitted under the name of
the field with .x appended, and the y-coordinate is submitted under the
name of the field with .y appended. Any VALUE attribute is ignored. The
image itself is specified by the SRC attribute, exactly as for the IMG
element.
NOTE: In a future version of the HTML standard, the IMAGE functionality
may be folded into an enhanced SUBMIT field.
- PASSWORD
-
Same as TEXT attribute, except that text is not displayed
as it is entered.
- RADIO
-
For attributes which can take a single value from a set of
alternatives. Each radio button field in the group should be given the
same NAME. Only the selected radio button in the group generates a
name/value pair in the submitted data. Radio buttons require an explicit
VALUE attribute.
- RESET
-
This is a button that when pressed resets the form's fields to
their specified initial values.
- SUBMIT
-
This is a button that when pressed submits the form. You can
use the VALUE attribute to provide a non-editable label to be displayed
on the button. The default label is application-specific.
The NAME attribute is a name/value pair to the submitted data if it has a
name and was the button that was pressed in order to submit the form.
- TEXT
-
Single line text entry fields. Use in conjunction with the SIZE and
MAXLENGTH attributes. Use the TEXTAREA element for text fields
which can accept multiple lines.
Value(s)
- TEXT
- PASSWORD
- CHECKBOX
- RADIO
- SUBMIT
- RESET
- IMAGE
- HIDDEN
Default Value
TEXT
VALUE
The initial value for the field, or the value
when checked for checkboxes and radio
buttons. This attribute is required for radio
buttons.
