使用React，一共两个页面，一个是物流信息，一个是收藏通知，每一个页面都要使用组件。还有一个需求，H5要长按1.5s，可以复制订单编号，也可以把本个组件删除。关于这两个组件，如何用最省事的方法写，比如那个编号的有和无，那个底部点击查看明细的有和无，有什么思路吗？小白求教。或者是有类似的例子也可以。项目时间不多，刚把RYF的demo和官方文档看了一下。

Do you use state to change the state of the component itself?
this.state = { showNumber:false }
<p style={{display:this.state.showNumber ? "" : "none"}}>Number</p>
