cgi popup_menu when radio is selected

[vit]

Dear Monks,
I have a hard time to find a way to show popup_menu() (HTML select) only in case if certain "radio" is checked.
Help me please, if possible.

Is there some reason you don't want to use JavaScript? If you don't use JS, then probably your only other option is AJAX. You might have a look at CGI::Ajax or some of the other Ajax modules on CPAN if that doesn't fit the bill.

[vit]

Just an opposite. I have nothing against js. If it's not too complicated for you may I ask you at least roughly to show how to use it for this case.

As ww said, you need to read up on JavaScript, but the basic would be to trigger an event when you check that radio button and use a JavaScript command to open a new window - assuming that's what you're after and proceed from there.

I think to achieve what you seem to be after that you're better off looking to Ajax as opposed to JavaScript because there are toolkits that I believe that will do that very quickly and then it's just a matter of gluing the code together with the requisite Perl modules. I'd suggest looking at the Dojo toolkit or script.aculo.us toolkit.

Good luck!

As someone else recently (and wisely) observed,

"Drop a coin in the COC (Crank Out Code) machine."

Or, on your own, read up on js and or the modules suggested above.

I'd do this on the client side with a little onclick to show the select tag. I do this a lot and it has nothing to do with Perl.

<input type="radio" value="1" name="foobar" />
<input type="radio" value="2" name="foobar" onclick="document.getEleme
+ntById('menu').style.visibility='visible'" />

<select name="somechoice" id="menu" style="visibility: hidden">
etc.

You could use display: none and display: block, the difference being display will collapse the space on the page where the menu would go.

Thanks a lot, it works fine. The only thing is that when I check another radio button select with this id="menue" should disapear.
If you could give me a hint how to do this I would appreciate.

[bradcathey]

Come on! You're not thinking...

<input type="radio" value="1" name="foobar" onclick="document.getEleme
+ntById('menu').style.visibility='hidden'" />

Hi. You will need to get the value passed in from the request and use it to supply which radio button should be checked. Tell us more and we can help you better.

[vit]

I want it to be a dynamic page, so that request is not sent yet. And when XXX is checked

<input type="radio" name="rad_server_type" value="xml">XXX;
<input type="radio" name="rad_server_type" value="org">YYY;

then this should be shown:

 print $q->popup_menu(-name=>'xml_server',-values=> \@array_of_selecti
+ons);

otherwise not. Something like "on....event" javascript
