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
