这里是是废话：小程序的一个简单案例，通过wx:if即可触发点击事件弹出遮罩层，只需要在view里面写入自己的其他需求即可

基础代码：

<!--pages/index/components/buy/index.wxml-->
<view class="box" >
  <view class="empty-box" bindtap="hideModal" id="empty-box"></view>
  <scroll-view scroll-y style="max-height:80vh;">
    <view class="content" style="transform:translateY({{translateY}}px);" animation="{{animate}}">
      <!-- boll -->
 <view style="height: 700rpx;"></view>
   
 
      <!-- 按钮 -->
      <view class="button" bindtap="confirm">
        <view>确认</view>
