    Ive got an ASP page with a form for registration.

    i want to implement a feature such that if a user clicks yes to one checkbox... then another form input type(say a dropdown box) is hidden, or greyed out?

    anyone done anything like this before, or able to point me in the right direction...?

    help!!! pretty please!!!

    rough idea from something that i have lying around. try working things out first in future :mad: it won't hurt half as much as you might think.

    <script language='javascript'>

    document.myform.send.disabled = true;
    document.onkeyup = proces;
    document.onmouseup = proces;
    document.onmousedown = proces;

    function proces()
    {
    if (document.myform.name.value == '')
    {document.myform.send.disabled = true;}
    else
    {document.myform.send.disabled = false;}
    }
    </script>

    probably doesn't work properly,etc. mneh!


    ... and the HTML ::

    <html>
    <body>
    <form name=myform>
    <input type=text name=name onchange='doIt()'>
    <input type=button value="Send (test)" name=send onclick='javascript:alert("This is only a test! Dimwittedmutha!")'>
    </body>
    </html>

    something like this?

    will need to be tweaked for netscape, but this should get you started


    <html>
    <head>
    <title>Nothing</title>
    <script language="javascript">

    function hidetextbox()
    {
    var cb = document.all.checkboxone;
    var tb = document.all.textboxone;
    if (cb.checked)
    {
    tb.disabled = true;
    tb.style.background = "#dddddd";
    }
    else
    {
    tb.disabled = false;
    tb.style.background = "#ffffff";
    }
    }

    </script>
    </head>

    <body bgcolor="#FFFFFF">
    <form method="get" action="whatever">
    <p>Check Box : <input type="checkbox" name="checkboxone" value="checkbox" onclick="hidetextbox()"></p>
    <p> Text Box : <input type="text" name="textboxone"></p>
    </form>
    </body>
    </html>



    bar
