如圖微信小程序中 scroll-view組件外div加display：flxed后， scroll-view組件滾動失效
github項目地址：https://github.com/fancaixia/wx-scroll-view
解決辦法:
scroll-view寬度為屏幕寬度，
子元素view.cont設(shè)置overflow:auto;內(nèi)容超出屏幕會出滾動條，然后便可以拖動了，
最外層header設(shè)置overflow-y: hidden;隱藏滾動條杖爽，實現(xiàn)了模擬scroll-view的效果
點擊view.green時 設(shè)置元素cur為當(dāng)前點擊view的offsetLeft
<view class="header">
<scroll-view class="scroll-view_H" scroll-x="{{true}}">
<view class="cont">
<view class="list">
<view class="green" wx:for="{{tags}}" wx:key="{{index}}" bindtap='fnclick'>{{item}}</view>
</view>
<view class="cur" style='left:{{left}}px'></view>
</view>
</scroll-view>
</view>
