我今天开发时碰到一个问题，就是如果我给父组件设置了高度的话，那么hidden属性就不会生效，截图如下：

wxml

<!-- 搜索框 -->
<view class="search">
  <view class="search_row">
    <input bindinput="handleInput" placeholder="请输入您要搜索的商品"></input>
    <!-- 隐藏的搜索框 带取消 开始 -->
    <view bindtap="handleCancel" hidden="{{!inputing}}">取消</view>
    <!-- 隐藏的搜索框 带取消 结束 -->
    <view hidden="{{true ? true : false}}"> Hidden </view>
  </view>
</view>

css

.search {
  height: 100vh;
  background-color: #dedede;
}
.search .search_row {
  padding: 10rpx;
  height: 50rpx;
  width: 100%;
  display: flex;
}
.search .search_row input {
  flex: 1;
  background-color: white;
  padding-left: 30rpx;
  border-radius: 5rpx;
  height: 50rpx;
  margin: 0 auto;
}
.search .search_row view {
  height: 50rpx;
  width: 100rpx;
  font-size: 26rpx;
  margin-left: 30rpx;
  display: flex;
  align-items: center;
  justify-content: center;
  background-color: #f8f8f8;
  border-radius: 5rpx;
}
