Question

我使用了一个自举面板，我添加了一个跨度可点击图标：当面板主体打开时加上当面板主体关闭时减去，我现在的问题是如何将其设置为默认关闭（加上默认显示的图标）当我点击它时，面板主体将会打开）

Answer 1

您可以使用已经拥有您需要的大部分逻辑的Bootstrap collapse组件：

<div class="panel-heading">
   <h3 class="panel-title">Panel 1</h3>
   <button class="btn btn-primary pull-right" type="button"
           data-toggle="collapse" data-target="#collapseExample">
      <i class="glyphicon glyphicon-plus"></i>
    </button>
</div>
<div class="collapse" id="collapseExample">
    <div class="panel-body">Panel content</div>
</div>

此外，您只需要一个小的JavaScript来更改按钮图标：

    $(document).on('click', '.panel-heading button', function(e) {
      var $this = $(this);
      var icon = $this.find('i');
      if (icon.hasClass('glyphicon-plus')) {
        $this.find('i').removeClass('glyphicon-plus').addClass('glyphicon-minus');
      } else {
        $this.find('i').removeClass('glyphicon-minus').addClass('glyphicon-plus');
      }
    });

        $this.find('i').removeClass('glyphicon-plus').addClass('glyphicon-minus');

Answer 2

你只需要改变这个：

<div class="panel-body">

对此：

<div class="panel-body"  style="display:none;">

并通过slideDown（）更改slideUp（），并通过slideUp（）更改slideDown（）。

同样改变这个：

<span class="pull-right clickable collapse in"><i class="glyphicon glyphicon-plus"></i></span>

对此：

<span class="pull-right clickable collapse in"><i class="glyphicon glyphicon-minus"></i></span>

现在你问题中提到的一切都应该有效。

删除div的班级展示

<div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">

到

<div id="collapseOne" class="collapse" aria-labelledby="headingOne" data-parent="#accordionExample">

Answer 4

我正在为你分享一个参考代码，只需按照代码，不需要任何点击功能，bootstrap'data-toggle =“collapse”'自动处理它。

CODE：

            <div class="panel-group" id="steps">
                <!-- Step 1 -->
                <div class="panel panel-default">
                    <div class="panel-heading">
                        <h4 class="panel-title">
                            <a data-toggle="collapse" data-parent="#steps" href="#stepOne"><SPAN TAG></a>
                        </h4>
                    </div>
                    <div id="stepOne" class="panel-collapse collapse">
                        <div class="panel-body">
                            <div class="form-group">
                                <label class="col-lg-2 control-label">Sub-Category Name</label>
                            </div>
                        </div>
                    </div>
                </div>
            </div>

只需将span标记放在其中并使用class pull-right，您需要的引导图标http://getbootstrap.com/components/

我希望这会奏效。
