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

Represents a boolean choice. A set of such elements with the same name represents an n-of-many choice field.

Example:

  <p>What flavors do you like?
  <input type=checkbox name=flavor value=vanilla>Vanilla<br>
  <input type=checkbox name=flavor value=strawberry>Strawberry<br>
  <input type=checkbox name=flavor value=chocolate checked>Chocolate<br>

HIDDEN

Represents a hidden field. The user does not interact with this field; instead, the VALUE attribute specifies the value of the field. The NAME and VALUE attributes are required.

Example:

    <input type=hidden name=context value="l2k3j4l2k3j4l2k3j4lk23">

IMAGE

Specifies an image resource to display, and allows input of two form fields: the x and y coordinate of a pixel chosen from the image. The names of the fields are the name of the field with `.x' and `.y' appended. `TYPE=IMAGE' implies `TYPE=SUBMIT' processing; that is, when a pixel is chosen, the form as a whole is submitted.

Example

    <p>Choose a point on the map:
    <input type=image name=point src="map.gif">

PASSWORD

A text field where the value is obscured as it is entered.

Example:

    <p>Name: <input name=login> Password: <input type=password name=passwd>

RADIO

Represents a boolean choice. A set of such elements with the same name represents a 1-of-many choice field.

Example:

    <p>Which is your favorite?
    <input type=radio name=flavor value=vanilla>Vanilla<br>
    <input type=radio name=flavor value=strawberry>Strawberry<br>
    <input type=radio name=flavor value=chocolate>Chocolate<br>

RESET

Represents an input option, typically a button, that instructs the user agent to reset the form's fields to their initial states. The VALUE attribute, if present, indicates a label for the input (button).

SUBMIT

Represents an input option, typically a button, that instructs the user agent to submit the form.

TEXT

Indicates a single line text entry field.

Example:

<p>Street Address: <input name=street><br>
Postal City code: <input name=city size=16 maxlength=16><br>
Zip Code: <input name=zip size=10 maxlength=10 value="99999-9999"><br>
