    make form fields available depending on user input

    Don't know what all is available to do this in (javascript, etc) so I am putting the question here.

    I have a form, when a user selcts a radio button such as credit card, check, or PO, certain fields should be available according to which one they select. How do I do this and in what platform?

    You can do this either with javascript (but using that would create an accessibility problem - and many browsers will have it turned of, anyway) or you can use a server side language such as php, and have a series of pages that display in accordance with the preceding on - you often see that in online shopping. It does mean loading of separate pages, but they should load quite quickly.

    What you need to do is place all fields, depending on what the user selects, within <div>. In other words, use CSS.

    Here is a quick example of what you can do:

    <form id="form1" name="form1" method="post" action="">
    <label>Credit Card</label>
    <input name="radiobutton" type="radio" value="radiobutton" onclick="credit.style.display=''; check.style.display='none'" /><br />
    <label>Check</label>
    <input name="radiobutton" type="radio" value="radiobutton" onclick="credit.style.display='none'; check.style.display=''"/><br />
    <div id="credit" style="display:none">
    <label>Card Number</label>
    <input name="creditNumber" type="text" />
    </div>
    <div id="check" style="display:none">
    <label>Check Routing</label>
    <input name="checkRouting" type="text" />
    </div>
    </form>
    Don't box me in; let me surf.
