先来一张效果图

html

<div class="transdata1">
 <ul class="tody-table-header2">
 <li>商品</li>
 <li>数量（kg）</li>
 <li>单价（元）</li>
 <li>金额（元）</li>
 </ul>
 <div id="detetion-box2">
 <div id="detetion-con1">
 <ul v-for="(item,index) in todayDetetion2" :key="index">
 <li>{{item.name}}</li>
 <li>{{item.amount}}kg</li>
 <li>{{item.price}}元/kg</li>
 <li style="color:rgba(0,255,204,1);">{{item.money}}元</li>
 </ul>
 </div>
 <div id="detetion-con2"></div>
 </div>
</div>

js

getData() {
 var _this = this;
 this.$axios
 .get("请求的url")
 .then(res => {
 this.todayDetetion2 = res.data.data;
 this.$nextTick(() => {
 this.ScrollUp2();
 });
 })
 .catch(err => {});
 },
 ScrollUp2() {
 var box = document.getElementById("detetion-box2");
 var con1 = document.getElementById("detetion-con1");
 var con2 = document.getElementById("detetion-con2");
 this.speed = 50;
 if (con1.offsetHeight >= box.offsetHeight) {
 con2.innerHTML = con1.innerHTML;
 var timer1 = setInterval(scrol, this.speed);
 function scrol() {
 /*判断滚动内容是否已经滚完，滚完了则滚动的值重新设置到0，否则就每个30默秒向上滚动1px */
 if (box.scrollTop >= con1.scrollHeight) {
 box.scrollTop = 0;
 } else {
 box.scrollTop++;
 }
 /*判断滚动的距离刚好为一条公告的高度时停掉定时器，隔1s之后重新启动计时器即可实现公告滚动停留效果 */
 if (box.scrollTop % 25 == 0) {
 clearInterval(timer1);
 setTimeout(() => {
 timer1 = setInterval(scrol, 30);
 }, 2000);
 }
 }
 }
 }

css(样式自己调)

.transdata1 {
 background: url("../../../static/img/transdata_bg.png") no-repeat center/100%
 100%;
 height: 237px;
 padding: 36px 28px 16px 20px;
 box-sizing: border-box;
 transform: translateY(-12px);
}
.tody-table-header2 {
 overflow: hidden;
}

.tody-table-header2 li {
 height: 24px;
 width: 82px;
 line-height: 24px;
 list-style: none;
 float: left;
 font-size: 13px;
 margin-right: 48px;
 font-family: MicrosoftYaHei;
 color: rgba(127, 250, 255, 1);
 text-align: center;
 background: url("../../../static/img/thead_bg.png") no-repeat center/100%;
 background-size: 100% 100%;
}
.tody-table-header2 li:last-child {
 margin-right: 0;
}
#detetion-box2 {
 margin-top: 13px;
 height: 150px;
 overflow: hidden;
}
#detetion-box2 ul {
 overflow: hidden;
 border-bottom: 1px solid #0e579c;
}
#detetion-box2 li {
 width: 82px;
 height: 24px;
 line-height: 24px;
 float: left;
 margin-right: 48px;
 font-size: 12px;
 color: #fff;
}
#detetion-box2 ul li:last-child {
 margin-right: 0;
}
