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。

Panel 1</h3>
<span class="pull-right clickable panel-collapsed in"><i class="glyphicon glyphicon-plus"></i></span>

<div class="panel-body">
Panel content</div>

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。
