Hope this help u..

There isn't a way to do it with one line?

You would have to use Jquery ....

http://jquery.com/

So what would the one line be?

if( $("#rbDevice").is(":checked") = true?

I don't program in java script so I don't know much about the syntax

You said :
>I am trying this :
>var ConTVal = $get("rbDevice").checked;

I propose you a working line doing the same thing with one line :
var ConTVal = $("#rbDevice").is(":checked");

OK, i will check it out in the morning.... if you don't mind my asking what was wrong with me code?

To use it :

if( $("#rbDevice").is(":checked") )
{
  // do something if true
}
else
{
  // do something if false
}

Select allOpen in new window

var ConTVall = $("#rbDevice").is(":checked")

is giving me false every time...

rbDevice is the id of the button radio

<input id="rbDevice" type="radio" name="rbgType" value="0" />Device

I don't know if this makes a diffrence but there are two rb next to each other: this is the html'

<td style="text-align:left" class="summaryBlackLabel">
                                                            Type:<br />
                                                            <input id="rbDevice" type="radio" name="rbgType" value="0" />Device
                                                        <br />
                                                        <input id="rbControl" type="radio" name="rbgType" value="1" />Controller
                                                        </td>

No problem. Check my test page

$("radio:checked").val()
will return the checked value..


if ( $("radio:checked").val()  == "the1iWant" ){
// its checked
}

WilliamStam is absolutely right, :checked selectod should be used that way
