[jquery] 부트 스트랩 3 Chevron 아이콘으로 쇼 상태 축소

Collapse 의 Bootstrap 3 Javascript 예제 페이지 에서 가져온 핵심 예제를 사용하여 갈매기 형 아이콘을 사용하여 축소 상태를 표시 할 수있었습니다.

나는 이것을 사용하여 일하고있다 :

$('#accordion .accordion-toggle').click(function (e) {
    var chevState = $(e.target).siblings("i.indicator").toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
    $("i.indicator").not(chevState).removeClass("glyphicon-chevron-down").addClass("glyphicon-chevron-up");
});

이것은 작동하지만 (모든 브라우저에서 완전히 테스트되지는 않았지만) 더 우아한 해결책이 있는지 궁금합니다.

이상적으로 핵심 기능을 사용하고 싶지만 동일한 결과를 얻는 방법을 잘 모르겠습니다.

$('#accordion').on('hidden.bs.collapse', function () {
    //do something...
})

다음은 jsfiddle 의 작동 버전입니다 .

다음 HTML의 경우 ( Bootstrap 3 예제에서 ) :

.panel-heading .accordion-toggle:after {
    /* symbol for "opening" panels */
    font-family: 'Glyphicons Halflings';  /* essential for enabling glyphicon */
    content: "\e114";    /* adjust as needed, taken from bootstrap.css */
    float: right;        /* adjust as needed */
    color: grey;         /* adjust as needed */
}
.panel-heading .accordion-toggle.collapsed:after {
    /* symbol for "collapsed" panels */
    content: "\e080";    /* adjust as needed, taken from bootstrap.css */

이런 종류의 코드를 사용할 수 있습니다.

function toggleChevron(e) {
    $(e.target)
        .prev('.panel-heading')
        .find('i.indicator')
        .toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
}
$('#accordion').on('hidden.bs.collapse', toggleChevron);
$('#accordion').on('shown.bs.collapse', toggleChevron);

=> 작동하는 JsFiddle

답변

Bludream의 답변 개선 :

FontAwesome을 확실히 사용할 수 있습니다!

“패널 제목”클래스와 함께 “축소됨”을 포함해야합니다. “축소 된”클래스는 패널을 클릭 할 때까지 포함되지 않으므로 올바른 갈매기 형 표시를 위해 “축소 된”클래스를 포함 시키려고합니다 (즉, 축소 된 경우 갈매기 형 오른쪽이 표시되고 열려있는 경우 갈매기 형 아래로 표시).

HTML

<div class="panel panel-default">
    <div class="panel-heading collapsed" data-toggle="collapse" data-target="#collapseOrderItems1">Products 1 <i class="chevron fa fa-fw" ></i></div>
    <div class="collapse" id="collapseOrderItems1">
        <p>Lorem ipsum...</p>
    </div>
</div>

CSS

.panel-heading .chevron:after {
    content: "\f078";
}
.panel-heading.collapsed .chevron:after {
    content: "\f054";
}

또한 기존 클래스를 사용하는 대신 새 클래스를 작성하는 것이 좋습니다.

biggates와 steakpi 덕분입니다. 질문 Dreamonic의 답변으로, 나는 모든 헤더를 클릭 할 수 있도록 (제목 문자열과 문양뿐만 아니라) 약간 변경하여 링크에서 밑줄을 그렸습니다. 아이콘을 같은 줄에 표시하려면 CSS 명령 끝에 h4를 추가했습니다. 다음은 수정 된 코드입니다.

답변

다음은 HTML에서 모든 종류의 전환 콘텐츠를 처리 할 수있는 몇 가지 순수한 CSS 도우미 클래스입니다.

전환해야하는 모든 요소와 작동합니다. 어떤 레이아웃이든간에 토글 요소 내에 .if-collapsed 및 .if-not-collapsed 클래스가있는 몇 개의 요소 안에 배치하면됩니다.

유일한 캐치는 토글의 원하는 초기 상태를 설정해야한다는 것입니다. 처음 닫힌 경우 접힌 상태로 두십시오. 경우 토글에 클래스 .

또한 : not 선택기 IE8에서는 작동하지 않습니다.

HTML 예 :

<a class="btn btn-primary collapsed" data-toggle="collapse" href="#collapseExample">
  <!--You can put any valid html inside these!-->
  <span class="if-collapsed">Open</span>
  <span class="if-not-collapsed">Close</span>
</a>
<div class="collapse" id="collapseExample">
  <div class="well">
    ...
  </div>
</div>

적은 버전 :

[data-toggle="collapse"] {
    &.collapsed .if-not-collapsed {
         display: none;
    }
    &:not(.collapsed) .if-collapsed {
         display: none;
    }
}

CSS 버전 :

[data-toggle="collapse"].collapsed .if-not-collapsed {
  display: none;
}
[data-toggle="collapse"]:not(.collapsed) .if-collapsed {
  display: none;
}

나는 이것이 오래되었다는 것을 알고 있지만 2018 년 이래 지금은 코드를 단순화하고 쉐브론을 축소 여부에 따라 회전시켜 사용자 경험을 향상시켜 더 나은 답변을 줄 것이라고 생각했습니다. 그러나 FontAwesome을 사용하고 있습니다. CSS는 다음과 같습니다.

a[data-toggle="collapse"] .rotate {
   -webkit-transition: all 0.2s ease-out;
   -moz-transition: all 0.2s ease-out;
   -ms-transition: all 0.2s ease-out;
   -o-transition: all 0.2s ease-out;
   transition: all 0.2s ease-out;
   -moz-transform: rotate(90deg);
   -ms-transform: rotate(90deg);
   -webkit-transform: rotate(90deg);
   transform: rotate(90deg);
}
a[data-toggle="collapse"].collapsed .rotate {
   -moz-transform: rotate(0deg);
   -ms-transform: rotate(0deg);

나는 오른쪽에서 부트 스트랩을 사용하여 쉐브론을 패널 제목의 오른쪽 끝까지 당기고 전체 너비와 반응성을 가져야합니다. CSS는 모든 애니메이션 작업을 수행하고 패널이 축소되었는지 여부에 따라 셰브론을 회전시킵니다. 단순한.
