RE: Validator JavaScript and html:radio buttons
Matt, Are you using the Struts html:radio tag to display the radio buttons? If so, you should initialize the field in the FormBean that contains the value of the radio button so that Struts marks one of the buttons as 'checked' for you.

RE: Validator JavaScript and html:radio buttons
Hi Matt,
As the other said I would suggest to have one button already selected unless
your business logic says not to suggest something to the user.
I think your generated Javascript doesn't check to see if at least one
button is selected. Can you post the JS code and the code for the submit
button?
>From the top of my head, you should have something like this in your
Javascript code:
function Validation() {
-
if (document.FormName.outcome.value == "") {
alert("Please choose one outcome !")
document.FormName.outcome.focus()
return
}
-
document.FormName.submit()
}
I'm not sure if you should check for "" or null.
HTH,
Cezar

Hi all. I have two radio buttons on a page, one both
named "outcome" one with the value of "Accepted" and
one with the value of "Rejected". In my
validation.xml file, I say that outcome is required.
The Javascript checking generated by the Validator
framework doesn't give an error if neither on is
selected, however the backend will, and produce an
error I can see with the tag.
How do I get the javascript to check the radio buttons
to make sure one is selected?

RE: Validator JavaScript and html:radio buttons
> IIRC, it's invalid HTML unless exactly one of the radio > button options is selected. That's not true. Not really. From the specs: Radio buttons are like checkboxes except that when several share the same control name, they are mutually exclusive: when one is switched "on", all others with the same name are switched "off". The INPUT element is used to create a radio button control. If no radio button in a set sharing the same control name is initially "on", user agent behavior for choosing which control is initially "on" is undefined. Note. Since existing implementations handle this case differently, the current specification differs from RFC 1866 ([RFC1866] section 8.1.2.4), which states: At all times, exactly one of the radio buttons in a set is checked. If none of the elements of a set of radio buttons specifies `CHECKED', then the user agent must check the first radio button of the set initially. Since user agent behavior differs, authors should ensure that in each set of radio buttons that one is initially "on". Authors _should_ pre-check one item, but are not required to. Since it's not possible in most UI's to set a radio group back to "no items selected" it's usually bad design to have none selected initially. The user can't restore the form to its original state if they accidently click in the wrong place. I would be able to tell you why the JS is failing if you post the source, but a better solution might be to re-think your design and consider whether a group of radio buttons is really the interface you want to use.

IIRC, it's invalid HTML unless exactly one of the radio button options is selected. In your case I'd pre-select whichever value makes sense and expect the user to change it if they don't like that choice. No idea about the JavaScript though, sorry! -- Wendy Smoak Applications Systems Analyst, Sr. Arizona State University, PA, IRM
