先看一下动态效果
Y轴滚动公告的原理是swiper
组件在页面中的Y轴滚动,属性vertical
,其余属性也设置一下autoplay circular interval="3000"
X轴滚动的原理是,利用动画效果,将内容从右往左过渡过去
wxml:
<!-- Y轴滚动公告 -->
<view class="wrapY">
<swiper
class="swiper_wrap"
vertical
autoplay
circular
interval="3000"
>
<block class="block_wrap" wx:for="{{items}}">
<swiper-item>
<view class="itemCon">{{item.title}}</view>
</swiper-item>
</block>
</swiper>
</view>
<!-- X轴滚动公告 -->
<view class='wrapX'>
<view class="wrapOut">
<view class="wrapInner">
<view class="contant">{{notice}}</view>
</view>
</view>
</view>
