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>
