另一种形式：

WXML

<!-- 弹幕轮播 -->
<swiper class="swiper_container" vertical="true" autoplay="true" circular="true" interval="2000">
	<block wx:for="{{msgList}}">
		<swiper-item style="display:flex;">
			<view class="sw-img">
				<van-image width="50rpx" height="50rpx" round fit="cover" src="{{item.img}}" />
			</view>
			<view class="swiper_item">{{item.title}}</view>
			<view class="user-action">{{item.action}}</view>
		</swiper-item>
	</block>
</swiper>

WXSS

/* 弹幕轮播 */
.swiper_container {position: fixed;bottom: 100px;height: 50rpx;width: 100%;margin-left:15px;z-index: 100;color: #fff;}
