Attribute for <INPUT ...>
NAME
NAME assigns a name to the input field, and is required in most circumstances. In forms which use CGI, the name of the input field is sent to the CGI:
| this code |
produces this |
<FORM ACTION="../cgi-bin/mycgi.pl">
favorite color: <INPUT NAME="favecolor">
<P><INPUT TYPE=SUBMIT VALUE="submit">
</FORM>
|
|
For radio buttons and
submit buttons you can use the same name
in more than one input to indicate different options. Notice in these examples that the names are the same but the values for each option change:
| this code |
produces this |
<FORM ACTION="../cgi-bin/mycgi.pl">
What size pizza?<P>
<INPUT TYPE=RADIO NAME="pizzasize" VALUE="S">small<BR>
<INPUT TYPE=RADIO NAME="pizzasize" VALUE="M">medium<BR>
<INPUT TYPE=RADIO NAME="pizzasize" VALUE="L">large<P>
<INPUT TYPE=SUBMIT VALUE="submit">
</FORM>
| |
<FORM ACTION="../cgi-bin/mycgi.pl">
Go to the check-out page?
<INPUT TYPE=SUBMIT NAME="checkout" VALUE="YES">
<INPUT TYPE=SUBMIT NAME="checkout" VALUE="NO">
</FORM>
| |
Forms that use scripting also use NAME. The input object is in the elements collection of the form object, and can be referred to by its name using dot notation. In this example, we use
the this.form.email to refer to the email input field. This code requests an email
address. If none is given, the form is not submitted.
<FORM
ACTION="../cgi-bin/mycgi.pl"
onSubmit="return (this.email.value != '')"
>
email: <INPUT NAME="email">
<P><INPUT TYPE=SUBMIT VALUE="submit">
</FORM>
