    Checked radio button triggering verification of other fields

    Hello,

    I am working with a form in which I want a text field to be required ONLY if a certain radio button (with a value of "yes") is checked.

    Here is what I have so far: verification for ensuring that one of the radio buttons is checked and verification to ensure that the related field is filled out.

    However I can't get one to be contingent upon the other. Below is my code (also attached in txt format if you prefer).

    Please help...
    Thanks!
    Jennifer

    I'm not sure if I'm doing what you needed to be done, but I think I did. I couldn't figure out how to do it with radio buttons, but if they are just yes/no, why not just have a checkbox marked yes? Then they can choose yes/no through that. Here is the code (very simple and ugly in a browser), I'll also upload a text file.

    ------------------------------------
    <html>
    <head>
    <script type="text/javascript">
    function validate()
    {
    x=document.myform
    chk=x.check.checked
    txt=x.textf.value
    if (chk)
    {
    if (txt)
    {
    return true
    }
    else
    {
    alert("You must enter text")
    return false
    }
    }
    }
    </script>
    </head>
    <body>
    <form name="myform" action="test.htm" onsubmit="return validate()">
    <input type="checkbox" name="check">Yes<BR>
    If yes, enter a value:
    <input type="text" name="textf">
    <input type="submit" value="Send input">
    </form>
    </body>
    </html>
    ---------------------------------

    Hope this helps!

    You can change the value of another field (If this is what you want!) by clicking a radio button.

    <input type="radio" name="radioset" onClick="form.otherField.value = 'whatever';">

    I am not sure if that is exactly what you want, but I hope it helps!
