[Javascript] Reset the value of a SET of fields

[Flavio Gomes]

David,

  well.... there are html errors in your code:
  "type=first_name_1" is not valid. Probably you wanted to write 
something like this:

<input type="text" name="first_name_1" size="10">

Right? And in your function you may refer to "first_name_1" element this way:

<script language=javascript>
function clear_row(form_name, num)
{
	oFirstName = document.getElementsByName('first_name_' + num);
	oLastName  = document.getElementsByName('last_name_' + num);
	oEmail     = document.getElementsByName('e_mail_' + num);

        oFirstName[0].value = ''; // [0] is used because the function
        oLastName[0].value  = ''; // returns an array with all objects
        oEmail[0].value     = ''; // that match the passed name.
}
</script>
