scroll-into-view设置了高度，list 和值分开，为什么还是不能滚动？
<scroll-view scroll-y style=“height:{{height}}px” scroll-into-view=“{{toList}}”>
<view wx:for=“{{allContentList}}” wx:key=“item” wx:for-item=“itemName” id=“item{{index}}”>
this.setData({
allContentList: that.data.allContentList
})
this.setData({
toList: ‘item’ + this.data.allContentList.length
})
