Question

请考虑以下jQuery代码片段

function toggleIcon(e) {
   $(e.target)
   .prev('.panel-heading')
   .find(".more-less")
   .toggleClass('glyphicon-plus glyphicon-minus');
}
$('.panel-group').on('hidden.bs.collapse', toggleIcon);
$('.panel-group').on('shown.bs.collapse', toggleIcon);

以上代码位于$(document).ready(function(){});

内

标记看起来像：

   <div class="panel-group" id="collapse">
    <div class="panel panel-primary">
        <div class="panel-heading">
            <h4 class="panel-title"><a data-parent="#collapse" data-toggle="collapse" href="#collapse-one"><i class="more-less glyphicon glyphicon-plus"></i> Item Details
            <span class="badge pull-right" id="itemdetails">0</span></a></h4>
        </div>
        <div class="panel-collapse collapse in" id="collapse-one">
            <div class="panel-body">
                @for (int i = 0; i < Model.MyList.Count; i++) {
                <div class="panel panel-info">
                    <div class="panel-heading">
                        <h4 class="panel-title"><a data-toggle="collapse"
                        href="#@Model.MyList[i].Number"><i class="more-less glyphicon glyphicon-plus">@Model.MyList[i].Number, @Model.MyList[i].PropA, @Model.MyList[i].PropB</i></a></h4>
                    </div>
                    <div class="panel-collapse collapse" id="@Model.MyList[i].Number">
                        <div class="panel-body"></div>
                    </div>
                </div>
            </div>
        </div>
        }
    </div>
</div>

这适用于除第一个之外的每个面板。第一个面板将始终打开，而不是添加加号，它会添加减号。第一个面板具有类panel-collapse collapse in，可确保在页面加载时打开面板。

请注意，我有嵌套面板，这也适用于那些，它只是第一个导致我出现问题的面板

有人可以告诉我，我做错了吗。

我试过这个请参考下面的代码：

<强> HTML ：

<div class="panel-group" id="accordion">

  <div class="panel panel-default">
    <div class="panel-heading">
      <h4 class="panel-title">
        <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo">
           Collapsible Group Item #2 
        </a><i class="indicator glyphicon glyphicon glyphicon-plus  pull-right"></i>
      </h4>
    </div>
    <div id="collapseTwo" class="panel-collapse collapse">

      </h4>
    </div>
    <div id="collapseThree" class="panel-collapse collapse">
      <div class="panel-body">

    </div>
  </div>
</div>

JavaScript代码：

$('#accordion').on('hidden.bs.collapse', function () {
    //do something...
})
$('#accordion .accordion-toggle').click(function (e) {
    var chevState = $(e.target).siblings("i.indicator").toggleClass('glyphicon-minus glyphicon-plus');
    $("i.indicator").not(chevState).removeClass("glyphicon-minus").addClass("glyphicon-plus");
});
