<HR><H2><A NAME="type">TYPE</A></H2>
Defines the type of data the field accepts. Defaults to free text. Several
types of fields can be defined with the type attribute:
<dl>
<dt>CHECKBOX
<dd>
Represents a boolean choice.
A set of such elements with the same name represents an n-of-many
choice field.
<p>Example:
</p>
<pre>
<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>
</pre>
<dt>HIDDEN
<dd>
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.
<p>
Example:
</p>
<pre>
<input type=hidden name=context value="l2k3j4l2k3j4l2k3j4lk23">
</pre>
<dt>IMAGE
<dd>
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.
<p>Example</p>
<pre>
<p>Choose a point on the map:
<input type=image name=point src="map.gif">
</pre>
<dt>PASSWORD
<dd>
A text field where the value is obscured as it is entered.
<p>Example:</p>
<pre>
<p>Name: <input name=login> Password: <input type=password name=passwd>
</pre>
<dt>RADIO
<dd>
Represents a boolean choice. A
set of such elements with the same name represents a 1-of-many choice
field.
<p>Example:</p>
<pre>
<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>
</pre>
<dt>RESET
<dd>
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).
<dt>SUBMIT
<dd>
Represents an input option,
typically a button, that instructs the user agent to submit the form.
<dt>TEXT
<dd>
Indicates a single line text entry field.
<p>Example:</p>
<pre>
<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>
