WeChat Mini Programs < scroll-view > cannot trigger the bindscroll event. The fixed height and sliding direction are set. Please solve the problem. 

<scroll-view wx:if="{{isShow}}" class="showBigPic" scroll-x scroll-width-animation style="width:100%;height:{{scrollheight}}px" bindscroll="getScroll">
  <block wx:for="{{cloudPic}}" wx:for-index="index" wx:for-item="item" wx:key="{{index}}">
    <view style="height:{{scrollheight}}px"><image class="showBigPic" src="{{item.picId[0]}}" mode="widthFix" bindtap="closeBigPic"></image></view>
  </block>
</scroll-view>
// 
onLoad: function() {
    var p = this
    wx.getSystemInfo({
      success: function(res){
        p.setData({
          scrollheight: res.windowHeight
        })
      }
    })
}
getScroll: function(e){
    // 
    console.log(e)
}
// 
closeBigPic: function() {
    this.setData({
      isShow: false
    })
  },

looked up a lot, basically said that the fixed height and sliding direction are not set, but I have set this, still can not trigger the bindscroll event

wxml 

<scroll-view wx:if="{{isShow}}" class="showBigPic" scroll-x scroll-width-animation style="width:100%;height:{{scrollheight}}px" bindscroll='getScroll'>
  <view class="cont">
    <block wx:for="{{cloudPic}}" wx:for-index="index" wx:for-item="item" wx:key="{{index}}">
      <view class="boxes" style="height:{{scrollheight/3}}px;background:{{arr[index]}}">
      </view>
      <!-- <image class="showBigPic" src="{{item.picId[0]}}" mode="widthFix" bindtap='closeBigPic'></image> -->
  </block>
  </view>
</scroll-view>

wxss 

.cont{
  width:1500px;
}

.cont{
  display:flex;
  flex-direction: row;
}

.boxes{
  width:250px;
}

js 

Page({
  data: {
    isShow:false,
    scrollheight:"",
    cloudPic: [1,2,3,4,5],
  },
  getScroll: function(e) {
    // 
    console.log(e)
  },
  showI(){
    this.setData({
      isShow:true,
      arr:['red','green','blue']
    })
  },
  // 
  closeBigPic: function() {
    this.setData({
      isShow: false
    })
  },
  onLoad: function() {
    var me =this;
    wx.getSystemInfo({
      success: function (res) {
        me.setData({
          scrollheight: res.windowHeight
        })
      }
    })
  }
})

I still haven't solved it according to this way
