badge的组件怎么如图一样放在最后面？
<div class="panel-body"> <div class="alert alert-info" role="alert"> 订单审批<span class="badge">42</span> </div> <div class="alert alert-info" role="alert"> 收款确认<span class="badge">42</span> </div> <div class="alert alert-info" role="alert"> 付款确认<span class="badge">42</span> </div> </div>
