Detecting checked radio button on UI dialog

Here is container for jquery UI dialog filled with radio buttons:


<div id="gfdialog" title="Meldung vom Website">
            <div>xxxxxxxxxxxxxxxxxx?</div>
            <input type="radio" name="radLstCopyType" value="1" checked="checked" /><span>Option 1</span>
            <div style="margin-left: 21px!important; margin-bottom: 15px;">Option 2.</div>
            <input type="radio" name="radLstCopyType" value="3" />
            <span>Szenario-CFG</span>
            <div style="margin-left: 21px!important; margin-bottom: 15px;">Option 3</div>
            <input type="radio" name="radLstCopyType" value="2" />
            <span>Muster-CFG</span>
            <div style="margin-left: 21px!important; margin-bottom: 15px;">xxxxxxxxxxxxxxxxxx.</div>
        </div>

; and here is code that gets checked radio button:


function RegisterGFCopyBGDialog() {          
            $("#gfdialog").dialog({
               
                autoOpen: false,
                width: 400,
                buttons: [
                    {
                        text: "Ok",
                        click: function () {
                            var selectedCFG_artId = $('input[name="radLstCopyType"]:checked').val();                          
                           
                            if (selectedCFG_artId == null) return;
                            __doPostBack('radLstCopyType', selectedCFG_artId);
                            $(this).dialog("close");
                        }
                    },
                    {
                        text: "Abbrechen",
                        click: function () {
                            $(this).dialog("close");
                        }
                    }
                ]
            });
        }


Most important part is  :

$('input[name="radLstCopyType"]:checked').val();                           

and NOT:

$('input[name="radLstCopyType"][checked="checked"']).val();                          

or

$('input[name="radLstCopyType"][checked="true"']).val();                          

or

$('input[name="radLstCopyType"][checked]).val();                          

UI Mockup tools

I never can't remember where to find them when you quickly need one.
So here it is.
If you only once had short deadline to deliver UI app mockup then you could use some of these.
