我使用 Bootstrap 面板，并添加了一个跨度可点击图标:当面板主体打开时加号，当面板主体关闭时减号，我现在的问题是如何将其设置为默认关闭(加号图标默认显示，当我单击它面板主体将打开)
在我的代码上方执行此操作，在此先感谢您的帮助。

最佳答案
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() 改变slideUp()，通过slideUp() 改变slideDown()。
也改变这个:
<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>
正如您现在在问题中提到的那样，一切都应该正常工作。
