jquery - select = selected で動作するように折りたたみプラグインを変更します

Question

<select>変更時にdivを非表示/表示するように使用しようとしています。

Twitterのブートストラップ崩壊プラグインを利用したいです。

私はこの例で半分働いていますhttp://plnkr.co/edit/9lPe61?p=preview

しかしselected、選択に追加すると、すべてが壊れます: http://plnkr.co/edit/w9XW8R?p=preview

<div class="accordion" id="accordion" >
    <div class="accordion-group">
      <select class="accordion-toggle">

         <option value="3" data-toggle="collapse" data-parent="#accordion" data-target="#collapseThree">3</option>
      </select>

      <div id="collapseOne" class=" collapse in">

JS - プラグインに追加して、selected="selected"選択でも機能するかどうかを確認する必要があると思いますが、どこに行く必要があるのかわかりませんか?

ＯＰ、

このhttp://plnkr.co/edit/qfB8Uf?p=previewはあなたが求めているものだと思います。

JS

...
  $('document').ready(function () {
      $(".accordion-dropdpwn").on('change', function (e) {
          var selected_value = $(this).val(),
          $target_elem = $('a[href="' + selected_value + '"]');
          $target_elem.trigger('click');
      });

      $('.accordion-toggle').on('click', function () {
          var selected_value = $(this).attr('href');
          $(".accordion-dropdown option").removeAttr('selected');
          $('option[value="' + selected_value + '"]').attr('selected', 'selected');
      });

      $(".accordion-dropdown").trigger('change');
  });

...

簡単に

のchangeイベントは選択された(子) のを<select>返すため、ユーザーがドロップダウンを変更したときに影響を受けるはずのアコーディオンへの参照を詰め込みました。valueoption<a>

参照を取得したら、その項目でクリックイベントをトリガーするだけです。もう 1 つの重要な点は、ページが読み込まれたときに、アコーディオンがの現在の状態を反映するようにするselectことです。optionselected="selected"

最後に、双方向制御があります。ユーザーがを変更する<select>と、アコーディオンが変更されるため、アコーディオンをクリックするとが変更されることが期待され<select>ます。

お役に立てれば。

まず、私は少し怠惰です。JavaScript、HTML、CSSを追加しました。

ここでデモを表示します。

1つまたは2つのバグがあります。私はそれらを修正しようとします。

これは私にとってはうまくいきました（実際の例については、このjsFiddleを参照してください）：

HTML

...
<select class="custom-select custom-select--collapse" aria-label="Select option to collapse">
    <option value="" selected data-target=".collapse.show">-- Choose something --</option>
    <option value="Collapse 1" data-target="#collapse1">Collapse 1</option>
    ...
</select>
...

...
<div class="collapse mb-3" id="collapse1">Content Collapse 1</div>
<div class="collapse mb-3" id="collapse2">Content Collapse 2</div>
...

Jクエリ

// DEFINE TARGET
var target; 

// SELECT OPTION TO SHOW/HIDE COLLAPSIBLE CONTENT
$('.custom-select--collapse').on('change' , function() {
    
    $('.custom-select--collapse option').each(function() {
      if ( $(this).is(':selected') ) {
        // ASSIGN TARGET
        target = $(this).attr("data-target");
      }
      
      // HIDE ALL CONTENT IF SELECTED OPTION HAS NO VALUE
      if ( $(this).val() == "" ){
        $(target).collapse('hide');
      }else{
        $(target).collapse('toggle');
      }
  });
  
  console.log("TARGET = " + target);        
});
