直播平台软件开发，弹出半角遮罩层

基础代码：

wxml

 

<!--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>
      </view>
 
    </view>
  </scroll-view>
</view>

​

css

 

/* pages/index/components/buy/index.wxss */
 
.flex {
  display: flex;
  align-items: center;
}
 
.box {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  z-index: 1000;
  width: 100vw;
  height: 100vh;
  background: rgba(0, 0, 0, 0.5);
  display: flex;
  flex-direction: column;
}
 
.empty-box {
  flex: 1;
  
}
 
/* 内容视图 */
 
.content {
  width: 100vw;
  background: rgba(255, 255, 255, 1);
  opacity: 1;
  border-radius: 20px 20px 0px 0px;
  z-index: 1001;
}
 
/* 头部 */
 
.header {
  position: relative;
  height: 80rpx;
  width: 100vw;
}
 
.header > view {
  position: absolute;
  top: 26rpx;
  left: calc(50vw - 30rpx);
  width: 60rpx;
  height: 10rpx;
  background: rgba(161, 166, 175, 1);
  opacity: 0.6;
  border-radius: 6rpx;
}
 
/* 快递 */
 
.item {
  display: flex;
  align-items: center;
  justify-content: space-between;
  width: calc(100vw - 80rpx);
  padding: 0 40rpx;
  height: 100rpx;
  background: rgba(255, 255, 255, 1);
  opacity: 1;
}
 
.item-no-selected {
  width: 36rpx;
  height: 36rpx;
  background: rgba(255, 255, 255, 1);
  border: 2rpx solid rgba(112, 112, 112, 1);
  border-radius: 50%;
  opacity: 0.5;
}
 
.item-selected {
  width: 40rpx;
  height: 40rpx;
}
 
/* 按钮 */
 
.button {
  width: 100vw;
  padding: 80rpx 40rpx 20rpx 40rpx;
}
 
.button >view {
  width: calc(100% - 80rpx);
  height: 98rpx;
  border-radius: 50rpx;
  line-height: 98rpx;
  text-align: center;
  font-size: 32rpx;
  font-family: PingFang SC;
  font-weight: bold;
  color: rgba(255, 255, 255, 1);
  background: rgba(237, 58, 74, 1);
  opacity: 1;
}

 

实现点击显示

上面的是基础代码，方便大家快速复制粘贴😄，接下来通过按钮展示弹出遮罩层

新建按钮

 

 <view  style="width: 190rpx;height: 70rpx;margin-right: 5rpx;margin-left: 5rpx;justify-content: center;display: flex;flex-direction: row;align-items: center;border-radius: 10rpx;color: white;" bindtap="show_hideModal">获取授权码</view>

 

新建js事件：

 

show_hideModal:function(){
  let that=this;
  that.setData({
    hideModal:true
  })
}
