I'd use classes instead
<input type="text" name="opt[0][]" class="text test" /><br />
<input type="text" name="opt[0][]" class="text test" /><br />
<input type="text" name="opt[0][]" class="text test" /><br />
<input type="text" name="opt[0][]" class="text test" /><br />
<input type="text" name="opt[1][]" class="text test" /><br />
<input type="text" name="opt[1][]" class="text test" /><br />
<input type="text" name="opt[2][]" class="text test" /><br />
<input type="text" name="opt[2][]" class="text test" /><br />
<script type="text/javascript">
//<![CDATA[
alert($$('input.test').length);
//]]>
</script>
