은 체크 박스를 부모가 선택 될 때 이것은 자식 아래 노드와 검사를 본다

- Ic.make_tree(@ics).values.each do |root|

레일 그러나 나는 재귀 어디 싶지 부모 확인란은 직접적인 자식 외에 모든 자식 노드를 검사합니다. 아무도 내가 그것을 어떻게 할 수 있는지 안다?

Answer 1

이 경우 jQuery 라이브러리의 "find"메소드가 유용 할 수 있습니다.

문서 #update_ics_table 당신이 표시된 원하는 모든 자식 확인란을 포함 가정 http://api.jquery.com/find/

$('input[type=checkbox]').live('change',function(){ 
    if ($(this).attr('checked')){ 
     $('#update_ics_table').find('input:checkbox[id = "child-of-' + $(this).attr('value') + '"]').attr('checked', 'checked'); 
    } else { 
     $('#update_ics_table'.find('input:checkbox[id = "child-of-' + $(this).attr('value') + '"]').removeAttr('checked'); 
    } 
});
