checkbox - Can I use radio buttons/checkboxes in place of textboxes in a Javascript calculator? -

-

i have javascript calculator in users can enter quantities of products/features, , multiply quantity set price. then, result shows in textbox below. 2 questions are:

  1. i can use <select> options , specify value each 1 this:

<select name="site_em_4.99" onchange="calculatetotal(this.form)"> <option value=""> - select - </option> <option value="1">yes</option> <option value="0">no</option> </select>

however, won't let me same checkboxes/radio buttons. how can that?

two: can change script total shows actual text, vs in text field? thanks!

p.s. script can found here.

instead of having input total switch span (or else) id (let's "total"), , replace innerhtml

<script> function calculatetotal(frm) { ... document.getelementbyid('total').innerhtml = round_decimals(order_total, 2); ... } </script>
