上代码

<view class="mask" wx:if="{{mask}}">

view>


 <view class='search'>
   <input type='text' confirm-type="search" bindfocus="ineye" bindblur="outeye">input>
   <view class="search-bot" wx:if="{{searchWord === '搜索'}}" bindtap="onSearch" >搜索view>
   <view class="search-bot" wx:else hover-class="none" bindtap="searchNoValue">取消view>
view>

.mask {
	background-color: rgb(0,0, 0, .9);
	position: fixed;
	top: 55px;
	left: 0;
	width: 100%;
	height: 100vh;
}

Page({
  data: {
	mask: false, 			  // input 搜索框聚焦时遮罩层
  },
  
  ineye: function () {
	this.setData({
	  mask: true, 
	})
  },

  outeye: function () {
	this.setData({
	  mask: false, 
	})
  }
  
})
