TYPE

 [Local Convention]
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.

TEXT

VALUE

 [Local Convention]
