Атрибут TYPE (for input)
TYPE=CHECKBOX | FILE | HIDDEN | IMAGE | PASSWORD | RADIO | RESET | SELECT-MULTIPLE | SELECT-ONE | SUBMIT | TEXT | TEXTAREA
Specifies the type of intrinsic control.
CHECKBOX Used for simple Boolean
attributes or for attributes that can take multiple values at the same time. It
is represented by a number of check box fields, each of which has the same name.
Each selected check box generates a separate name/value pair in the submitted
data, even if this results in duplicate names. The default value for check boxes
is on .
FILE A file upload element.
HIDDEN No field is presented to
the user, but the content of the field is sent with the submitted form. This
value can be used to transmit state information about client/server interaction.
IMAGE An image field which you
can click, 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 Image element.
PASSWORD The same as the TEXT
attribute, except that text is not displayed as the user enters it.
RADIO Used for attributes that
accept 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 RESET is a button that
when pressed resets the form's fields to their specified initial values. The
label to be displayed on the button may be specified just as for the SUBMIT
SELECT-MULTIPLE Specifies a
multiple select list box.
SELECT-ONE Specifies a
single-select list box.
SUBMIT SUBMIT 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. If a SUBMIT button is pressed in order to
submit the form, and that button has a NAME=
attribute specified, then that button contributes a name/value pair to the
submitted data. Otherwise, a SUBMIT button makes no contribution to the
TEXT Used for a single-line
text-entry field. Use in conjunction with the SIZE=
and MAXLENGTH= attributes.
TEXTAREA Used for multiple-line
text-entry fields. Use in conjunction with the SIZE=
and MAXLENGTH= attributes.
