① The first way
Use position:fixed. Disable page scrolling.

1. Page structure html

<view class="indexPage {{proInfoWindow?&#39;indexFixed&#39;:&#39;&#39;}}">
-----------此处为整个页面的结构内容
<button catchTap="_proInfoWindowShow">点击显示弹窗</button>
</view>
// 当proInfoWindow为true的时候显示弹窗
<view wx:if="{{proInfoWindow}}">此处为弹窗内容</view>

2. CSS part

//添加一个类名, 把弹窗的下层内容定位为fixed.实现禁止滚动的效果
.indexFixed{
  position: fixed;
  top:0;//top:0可不写,否则显示弹窗的同时会使底层滚动到顶部.
  left:0;
  bottom:0;
  right:0;
}

三.JS part

Page({
 data: {
proInfoWindow:false,//控制弹窗是否显示  
},
// 点击弹窗事件, 设置proInfoWindow为true, 显示弹窗.
// 设置proInfoWindow为true的同时, 给页面添加了一个class名为indexFixed的类.显示弹窗时下层就禁止滚动,关掉弹窗时就可以滚动.
_proInfoWindowShow(){
  this.setData({
    proInfoWindow:true
})
}
})

②The second way

用 catchtouchmove="return"
//此处为弹窗内容
<view  catchtouchmove="return"> //外层加 catchtouchmove="return"仅触摸背景区域时不穿透底部.
<view  catchtouchmove="return"></view> //在每个小的区域内加 catchtouchmove="return"
<view> // 有需要滚动的列表区域位置不要加 catchtouchmove="return", 否则列表无法滚动
    <view>滚动列表1</view>
    <view>滚动列表2</view>
    <view>滚动列表3</view>
    <view>滚动列表4</view>
</view>
</view>
