Answer 1

可以在volist标签外加上php if语句如下：<?php if($list){?>
  <volist name='list' id='vo'>
                    <div class="coupons-box" id="couponsinfo">
                        <div class="coupons-info">
                            <div class="info-name tx-el" title="{$vo.name}">{$vo.name}</div>
                            <div class="info-content tx-el" title="{$vo.title}">{$vo.Coupon.title}</div>
                            <div class="info-tel tx-el" title="{$vo.telephone}">{$vo.telephone}</div>
                            <div class="info-address tx-el" title="{$vo.address}">{$vo.address}</div>
                        </div>
                    </div>
        </volist>
<?php }else{?>
<div style=" font-size:18px; color:#666; font-family:微软雅黑; text-align:center;width:980px; margin-top:20px;">暂无信息</div>
<?php }?>
