场景：

左侧导航栏，右侧内容

右侧内容 .wxml 文件

<scroll-view  scroll-y="true" bindscroll="onContentChange" style="width: 100%; height: 100%" scroll-into-view="{{contentToView}}">
      <view wx:for="{{lists}}" wx:key="id">
        <view class="content_item" id="{{item.id}}">{{item.name}}</view>
      </view> 
</scroll-view>

右侧内容 .js 文件

lists: [
      {id: "m001", name: 'view-m001'},
      {id: "m002", name: 'view-m002'},
      {id: "m003", name: 'view-m003'},
      {id: "m004", name: 'view-m004'},
      {id: "m005", name: 'view-m005'},
      {id: "m006", name: 'view-m006'},
      {id: "m007", name: 'view-m007'},
]

注意点：

• scroll-into-view="{{contentToView}}" 这是滚动指定的位置，主键id
• for循环后的每一项一定要设置id， id须同contentToView值一致
