jQuery dynamically generated radio buttons then value is passed to continue button

I have a page that receives a JSON response. If there is more than one option in the JSON it will dynamically generate some radio buttons using a for loop in Javascript based on the greater length.

Something like:

    for (var i = 0; i < length; i ++){
    alert(开发者_StackOverflowi);
        //draw the HTML radio buttons based on the data i++
    }
        //value from radio button button gets passed to a continue button 

What would be the best way to do that in jQuery?

Something like

for ( var i in json ) {
   var input = $('<input>', { 
     type: 'radio', name: 'group-name', 
     value: json[i], 
     'class': 'my_radio'
   } );
   $('body').append( input );
}

$('#continue').click( function() {
    var selected = null;
    $('input.my_radio').each( function() {
         if ( $(this).attr( 'selected' ) )
             selected = $(this).val();
    });
    // do something with selected....
});

You'll have to surround it with a form element if you need that. I haven't tested this, by the way.
