[Seaside] How do I use JQuery with Javascript variable

[Francisco Martins]

I'm trying to code some examples in the book I found JQuery JQuery in
Action, Second Edition.

The example has the following code snippet:

<script type="text/javascript">
      $(function(){
        $('#testButton').click(function(){
          var checkedValue = $('[name="someRadioGroup"]:radio:checked').val();
          $('#result').html('The radio element with value <tt>' +
checkedValue + '</tt> is checked.');
        });
      });
</script>

I do not know what to write on the line with a comment below:

	html document addLoadScript: (
			(html jQuery: #testButton) onClick: (
				(html jQuery: #result) load html: [:renderer| |checkedValue|
					checkedValue := 'What is equivalent to the code in the comment?'.
"var checkedValue =
$('[name=''someRadioGroup'']:radio:checked').val();"
					renderer html: 'The radio element with value <tt>' , checkedValue
, '</tt> is checked.'
				]
			)
	).

Thanks for any help.
