Attribute for <BUTTON ...>
TYPE =BUTTON |SUBMIT |RESET

TYPE indicates that the button is one of three types:

• BUTTON (the default) creates a button in the same way <INPUT TYPE=BUTTON> does. A button of this type requires a script for it to do anything.
• SUBMIT creates a submit button like <INPUT TYPE=SUBMIT>
• RESET creates a submit button like <INPUT TYPE=RESET>

<FORM ACTION="/cgi-bin/html/mycgi.pl" NAME="application">
application date: <INPUT TYPE=TEXT NAME="appdate" SIZE=10>
<BUTTON
TYPE=BUTTON
onClick="document.application.appdate.value=today()"><I>today</I></BUTTON><P>
<BUTTON TYPE=RESET><FONT COLOR=RED>Reset Form</FONT></BUTTON>
<BUTTON TYPE=SUBMIT><STRONG>Send It!</STRONG></BUTTON>
</FORM>
