vue 动态设置背景图片

backgroundImage需要做判断

 <div class="right-con" :style="{backgroundImage: 'url(' + (coverImgUrl ? coverImgUrl : baseImg) + ')', backgroundSize:'contain'}">
</div>

直接设置backgroundImage

 <div class="right-con" :style="{backgroundImage: 'url(' + coverImgUrl + ')', backgroundSize:'contain'}">
</div>
