图片描述

描述:

  • 如图所示,黑色框为屏幕,
  • 紫色框可以上下滑动,且上下滑动,滑动时绿色部分固定在最顶端,紫色框内类似 html 里的表格(小程序没有表格标签),
  • 粉色部分可左右滑动,且滑动时蓝色部分固定,绿色部分需跟随粉色部分滑动

我的代码

我的解决方法是一个y轴方向的scroll-view里面嵌套一个x轴方向的scroll-view,绿色部分绝对定位,top值动态修改。

  <!-- 紫色框,可上下滑动的 scroll-view-->
  <scroll-view class="quotation-wrapper" style="height:{{wHeight}}px;" scroll-y="true" bindscroll="scroll" bindscrolltoupper="scrolltoupper" bindscrolltolower="scrolltolower">

    <!-- 蓝色部分-固定 -->
    <view class="left-wrapper">
      <view class="left-th" style="{{leftThStyle}}">名称</view>
      <view wx:for="{{text}}" wx:key="{{item.rank}}">
        <view class="left-item"><view class="rank">{{item.rank}}</view>{{item.symbol}}</view>
      </view>
    </view>

    <!-- 粉色部分,可左右滑动的 scroll-view -->
    <scroll-view class="right-wrapper" scroll-x="true">
      <view class="right-th" style="{{thStyle}}">
        <view class="right-td">流通市值</view>
        <view class="right-td">价格</view>
        <view class="right-td">流通数量</view>
        <view class="right-td">成交额</view>
        <view class="right-td">涨幅(24h)</view>
        <view class="right-td">涨幅(7d)</view>
      </view>
      <block wx:for="{{text}}" wx:key="{{item.rank}}">
        <view class="right-item">
          <view class="right-item-prop">{{filter.format8(item.marketCapType)}}</view>
          <view class="right-item-prop">{{filter.formatUndefined(item.priceType)}}</view>
          <view class="right-item-prop">{{filter.format4(item.availableSupply)}}</view>
          <view class="right-item-prop">{{filter.format4(item.data24hVolumeType)}}</view>

          <view wx:if="{{item.percentChange24h > 0}}" class="right-item-prop" style="color:green;">+{{item.percentChange24h}}</view>
          <view wx:if="{{item.percentChange24h < 0}}" class="right-item-prop" style="color:red;">{{item.percentChange24h}}</view>

          <view wx:if="{{item.percentChange7d > 0}}" class="right-item-prop" style="color:green;">+{{item.percentChange7d}}</view>
          <view wx:if="{{item.percentChange7d < 0}}" class="right-item-prop" style="color:red;">{{item.percentChange7d}}</view>
        </view>
      </block>
    </scroll-view>
  </scroll-view>
Page({
  data: {
    text: quotationList,
    wHeight: 0,
    thStyle: 'position: absolute;top: 0;left: 0;'
   },
  onLoad: function() {
    var that = this
    wx.getSystemInfo({
      success: function(res) {
        that.setData({
          // 设置紫色框 scroll-view 的高度
          wHeight: (res.windowHeight - 40)
        })
      }
    })
  },
  //滚动过程中触发,设置 top 值为 scrollTop 值
  scroll: function(e) {
    this.setData({
      thStyle: 'position: absolute;top:' + e.detail.scrollTop + 'px;left: 0;',
      leftThStyle: 'position: absolute;top:' + e.detail.scrollTop + 'px;left: 0;'
    })
  }
})

效果图:

图片描述

出现的问题:

由于绿色部分(表头)定位的top值是上下滑动时使用setData来改变的,所以会一直触发setData,造成滑动卡顿不流畅。
想问问有没有好一些的解决办法。不局限于这个布局,更改布局能实现相同的效果也是可以的。
感谢!!

这个问题最终没有解决。
考虑到这个布局比较复杂,后续可能不好维护,和小程序轻量的定位,所以换了另外一种普通的方式来展示数据。
楼主已经换了公司,后续来的同学不用再浪费时间跟我要代码了,就这样。
