table

I'm working with rails and I don't know javascript. I have a table with a select_tag field and I want to have another field that capture the option selected, multiply for the price captured in another field and display the total. Like this

<table>
    <tr>
        <td>(select_tag)</td>
        <td>price</td>
        <td>total</td>
    </tr>
</table
