解决小程序点击弹出模态框,子父级都有滚动条问题

思考步骤:
1.使用<scroll-view>作为根节点包裹所有view,并动态绑定scroll-view的scroll-y属性<scroll-view scroll-y="{{isScroll}}">,自定义它的高度,var calc = clientHeight * rpxR-100; “-100”是因为我底部有选项卡,你若不需要就不用减;
2.点击button按钮触发showModel事件,子级内容显示,更改isScroll的值为false,关闭弹窗的点击事件中,更改isScroll的值为true

贴出主要代码
wxml文件

<view class="cusEdit"> <scroll-view scroll-y="true" style="height:{{winHeight}}rpx"> <view class="form-group first"> <ul class="basicMsg"> <li data-type="text" class=""> <view class="li-inner "> <span class="k">姓名</span> <span class="v"><input name="custName" placeholder="请输入姓名" type="text" ></input></span> </view> </li> <li data-type="text" class=""> <view class="li-inner "> <span class="k">意向级别</span> <span class="v"><button name="custName" placeholder="请选择" type="text" bindtap=‘showModel‘>请选择</button></span> </view> </li> </ul> </view> </scroll-view> //这个是子级内容 <scroll-view> <view id=‘cientWill‘ class="hide{{showView?‘show‘:‘‘}}"> </view> </scroll-view></view>

css文件

::-webkit-scrollbar{ width: 0; height: 0; color: transparent;}.hide{ display: none}.show{ display: block;}scroll-view{ width:100%; height:100%;}#cientWill{ position: fixed; width: 750rpx; height: 100vh; overflow: auto; padding: 0 20rpx; top: 0; left: 0; background:#fff; z-index: 999;}
