vant变量连接符的问题

Question

<div v-for="(item,ing) of infolist" :key="ing">
        <van-card
          tag="已过期"
          :title= item.carnum
          :desc= item.intodate+"00:00至"+item.intodate+"23:59"
          thumb="https://img01.yzcdn.cn/vant/ipad.jpeg"
        />
    </div>

请问怎么把
:desc= item.intodate+"00:00至"+item.intodate+"23:59"
这里的变量和字符串连接起来，总是报错：error Parsing error: unexpected-character-in-unquoted-attribute-value vue/no-parsing-error

Answer 1

:desc="item.intodate+'00:00至'+item.intodate+'23:59'"

Answer 2

<div v-for="(item,ing) of infolist" :key="ing">
        <van-card
          tag="已过期"
          :title="item.carnum"
          :desc="`${item.intodate}00:00至${item.intodate}23:59`"
          thumb="https://img01.yzcdn.cn/vant/ipad.jpeg"
        />
    </div>
