可以直接拷贝就用,这只是一个壳,可以往里面填充自己的内容<br />
在pick-header
里添加筛选项,在pick-container
添加被筛选的选项内容,content
里显示真正的内容。
content
的高度是会在js
里根据当前手机分辨率所动态计算的,高度值为contentHeight
,所以在里面可以嵌套一个scroll-view
,设置高度为contentHeight
即可实现内容滑动。<br />
好了,废话不多说,直接看图附代码。
wxml
<view class="content-container">
<view class="pick-header" bindtap="onPickHeaderClick">
筛选pick-header view z-index:60
</view>
<view class="pick-container {{needAnimation ? (openPicker ? 'slidown' : 'slidup') : ''}}" >
筛选项 pick-container view z-index:50

<view class="shadow" style="height:{{contentHeight}}px;line-height:{{contentHeight}}px" hidden=" {{!openPicker}}">我是半透明阴影遮罩 view shadow z-index:40</view>
<view class="content" style="height:{{contentHeight}}px">
