Bootstrap 表单验证formValidation 之比较两个input值的大小

<td style="min-width:325px;">
<div class="input-group " >
<div class="input-group-addon">最小时长</div>
<input type="text" class="form-control" name="minTime"  placeholder="不得小于10分钟" />
<div class="input-group-addon">分钟</div>
</div>
</td>
<td style="min-width:325px;">

<div class="input-group " >
<div class="input-group-addon">最大时长</div>
<input type="text" class="form-control" name="maxTime" placeholder="不得小于10分钟" />
<div class="input-group-addon">分钟</div>
</div>
</td>
