效果如圖：

程式碼如下：
wxml

//使用迴圈巢狀data資料格式寫對即可
<scroll-view class="left" scroll-y>   
    <view wx:for="{{left}}" class="leftlist {{index==_click?'yes':''}}" data-i="{{index}}" bindtap="tap">
      {{item.txt}}
    </view>
  </scroll-view>

<scroll-view class="right" scroll-y bindscroll
 
="scroll" scroll-into-view="{{toView}}">
    <view id="{{item.id}}"  wx:for="{{right}}">

      <view class="title">
        <text class="line"></text>
        {{item.txt}}
        <text class="line"></text>
      </view>  

      <view class="li" wx:for="
 
{{item.li}}">
        <image src="{{item.src}}"></image>
        <text class="name">{{item.name}}</text>
      </view>

    </view>
  </scroll-view>

js

Page({
  data: {
    toView: 'red1',
    _click:0,
    left: [{ txt: '新品', id: 'new' }, { txt: '手機', id: 'phone'
 
 }, { txt: '電視', id: 'mv' }, { txt: '電腦', id: 'computer' }],
    right: [
      { txt: '新品', id: 'new',li: [{ src: '../../assets/images/max1.jpg', name: '小米noto' }, { src: '../../assets/images/max1.jpg', name: '小米mix' }, { src: '../../assets/images/max3.jpg', name: '小米5c' }, { src: '../../assets/images/max2.jpg', name: '小米notp' }, { src: '../../assets/images/max2.jpg', name: '小米note5' }, { src: '../../assets/images/max2.jpg', name: '小米6' }]},

  },

  scroll: function (e) {
    console.log(e)//右側列表滑動-左側列表名稱樣式跟著改變，然而我不會寫，擱置中，誰會告訴我，謝謝！
  },
  tap: function (e) {  
    var j = parseInt(e.currentTarget.dataset.i);
    this.setData({
      toView: this.data.left[j].id,//控制檢視滾動到為此id的<view>
      _click:j                     //控制左側點選後樣式
        })
  },
})

友情提示：
一、左側點選樣式改變：
利用自身index與點選的元素的index比較。
data-i=“{{獲取當前index傳給_click儲存}}”，
class=”leftlist {{index==_click?’yes’:”}}”，
此處index是自身的，如果自身和點選的一致就新增，yes類名，否側滯空清除yes樣式。

二、點選左側，右側跟隨：
利用
scroll-into-view=”{{id}}”，
檢視會滾動到id為此id的view標籤。我是直接從data資料裡取得id，也可以直接獲取點選元素id。

三、迴圈巢狀：data資料格式寫對，按照官方文件就行。
