具体代码如下所示：
<div class="row cl">
<label class="form-label col-xs-4 col-sm-3"><span class="c-red">*</span>优惠券类型：</label>
<div class="formControls col-xs-8 col-sm-9 skin-minimal">
<div class="radio-box">
<input name="couponType" type="radio" value="1" id="couponType_1" <#if couponInfo.couponType == 1>checked</#if>>
<label for="couponType_1">满减券</label>
</div>
<div class="radio-box">
<input type="radio" name="couponType" value="2" id="couponType_2" <#if couponInfo.couponType == 2>checked</#if>>
<label for="couponType_2">折扣券</label>
</div>
<div class="radio-box">
<input type="radio" name="couponType" value="3" id="couponType_3" <#if couponInfo.couponType == 3>checked</#if>>
<label for="couponType_3">现金券</label>
</div>
<label id="couponType-error" for="couponType" class="error"></label>
</div>
</div>
<div class="row cl" id="couponMax_div">
<label class="form-label col-xs-4 col-sm-3">优惠最高金额：</label>
<div class="formControls col-xs-8 col-sm-9">
<input type="text" class="input-text" placeholder="仅在折扣券的情况下填写" name="couponMax" id="couponMax" value="${couponInfo.couponMax}">
</div>
</div> 其中，自定义错误提示位置只需修改
<label id="couponType-error" for="couponType" class="error"></label>所在的位置即可，id和for的内容可以在浏览器中F12查看到。
