反应：在页面加载时删除本地存储项

Question

这是我从本地存储中删除项目的功能

const removeItem = () => localStorage.removeItem("key")

页面加载时如何运行功能，请尝试此操作但不起作用

<div onLoad={removeItem}>
<h1>Successful payment landing page</h1>
</div>

Answer 1

useEffect(() => { 
    removeItem();
}, [])

Answer 2

尝试一下：

<div onLoad={this.removeItem}>
</div>


//paste this function anywhere above render()
removeItem() {
  localStorage.removeItem("key");
}
