Hi everyone.

My form page htm:

Expand|Select|Wrap|Line Numbers

 <html>

<head>

    <script language="javascript">

        function controlla_combo()

        {

            document.form1.Nacionalidad_text.disabled = document.form1.Nacionalidad[0].checked;

            document.form1.Nacionalidad_text.disabled = document.form1.Nacionalidad[1].checked;

        }

    </script>

</head>

<body>

    <form name="form1" action="insert.jsp" method=post> 

    <table>

        <tr>

            <td><input type="radio" name="Nacionalidad" value="1" onclick="controlla_combo();" CHECKED></td>

            <td><input type="radio" name="Nacionalidad" value="0" onclick="controlla_combo();"></td>

            <td><input type="radio" name="Nacionalidad" value="2" onclick="controlla_combo();"></td>

            <td>

                <select name="Nacionalidad_text" disabled>
 
    <OPTION VALUE="MX">México</OPTION>

    <OPTION VALUE="IT">Italia</OPTION>

    <OPTION VALUE="ES">España</OPTION>
 
                </select>

            </td>

        </tr>

    </table>

    </form>

</body>

</html>

I need this:

1) If checked input type="radio" name="Nacionalidad" value="1" the select name="Nacionalidad_text" is DISABLE;

2) If checked input type="radio" name="Nacionalidad" value="0" the select name="Nacionalidad_text" is DISABLE;

3) If checked input type="radio" name="Nacionalidad" value="2" the select name="Nacionalidad_text" is ENABLE;

The function function controlla_combo() NOT working... :

1) If checked input type="radio" name="Nacionalidad" value="1" the select name="Nacionalidad_text" is ENABLE;

2) If checked input type="radio" name="Nacionalidad" value="0" the select name="Nacionalidad_text" is DISABLE;

3) If checked input type="radio" name="Nacionalidad" value="2" the select name="Nacionalidad_text" is ENABLE;

Can you help me ?

your approach to the function is totally wrong. if you want the select enabled, check which radio is checked. (this requires a condition to be tested, thus use if () )
