[HTML] Form come questo...

[cicoandcico]

Come posso fare in html un form come questo? ho provato e riprovato ma non mi riesce di rendere inattivi i campi relativi a un radio button quando seleziono l'altro.

per farlo devi utilizzare un linguaggio di scripting come Javascript o anche PHP, l'html da solo non basta.

Codice PHP:

<script language="javascript">
function abilita()
{
    document.getElementById('tr_start_ip').disabled = false;
    document.getElementById('tr_end_ip').disabled = false;
    document.getElementById('tr_pdns').disabled = false;
    document.getElementById('tr_leasetime').disabled = false;
    document.getElementById('rbt_disable').checked = false;

}

function disabilita()
{
    document.getElementById('tr_start_ip').disabled = true;
    document.getElementById('tr_end_ip').disabled = true;
    document.getElementById('tr_pdns').disabled = true;
    document.getElementById('tr_leasetime').disabled = true;
    document.getElementById('rbt_enable').checked = false;
}
</script>

<form action="pagina.asp" method="post">
    <table border="0">
        <tr>
            <td>
                <input type="radio" id="rbt_enable" name="rbt_enable" onclick="return abilita();">&nbsp;Enable DHCP Server
            </td>
            <td>
            </td>
            <td>
            </td>
        </tr>
        <tr id="tr_start_ip" disabled>
            <td>
            </td>
            <td>
                Start IP
            </td>
            <td>
                <input type="text" id="start_ip" name="start_ip" value="192.168.0.1">
            </td>
        </tr>
        <tr id="tr_end_ip" disabled>
            <td>
            </td>
            <td>
                End IP
            </td>
            <td>
                <input type="text" id="end_ip" name="end_ip" value="192.168.0.255">
            </td>
        </tr>
        <tr id="tr_pdns" disabled>
            <td>
            </td>
            <td>
                Primary DNS
            </td>
            <td>
                <input type="text" id="pdns" name="pdns" value="192.168.0.2">
            </td>
        </tr>
        <tr id="tr_leasetime" disabled>
            <td>
            </td>
            <td>
                Lease Time
            </td>
            <td >
                <input type="text" id="leasetime" name="leasetime" value="2500">&nbsp;Seconds
            </td>
        </tr>
        <tr>
            <td>
                <input type="radio" id="rbt_disable" name="rbt_disable" onclick="return disabilita();" checked>&nbsp;Disable DHCP Server
            </td>
            <td>
            </td>
            <td>
            </td>
        </tr>
        <tr>
            <td colspan="4" align="center">
                <input type="submit" value="Modifica">

ho aggiornato il codice ora dovrebbe disabilitare l'intera tr così da far diventare disabilitato anche il testo accanto alle input-text

bye bye
