checkbox - jQuery: make checkboxes act like radio buttons?

Question

Is there a way to make checkboxes act like radio buttons? I assume this could be done with jQuery?

<input type="checkbox" class="radio" value="1" name="fooby[1][]" />
<input type="checkbox" class="radio" value="1" name="fooby[1][]" />
<input type="checkbox" class="radio" value="1" name="fooby[1][]" />

<input type="checkbox" class="radio" value="1" name="fooby[2][]" />
<input type="checkbox" class="radio" value="1" name="fooby[2][]" />
<input type="checkbox" class="radio" value="1" name="fooby[2][]" />

If one box was checked the others in the group would uncheck.

Answer 1

$("input:checkbox").click(function(){
    var group = "input:checkbox[name='"+$(this).attr("name")+"']";
    $(group).attr("checked",false);
    $(this).attr("checked",true);
});

This will do it, although i do agree this might be a bad idea.

UPDATE added group separation.
