单击时将数据传输到对话框

Question

我希望当点击我的手风琴时，这一行中的数据将进入我的对话框形式。但我没有收到表格中的任何数据。

为什么表单没有接收到数据？

Answer 1

单击时，我将对象的索引传递给数组，并将其发送到我创建的新数组

<IconButton onClick={async () => {
setData({ ...dataSearch[index] })
handleClickOpen()
}}
>
<EditIcon fontSize="small" alt="modifier" style={{ color: '#205723' }} />
</IconButton>

Answer 2

handleClickOpen似乎只是打开对话框，而不是调用setDataSearch({ ...dataSearch, [name]: value })，后者似乎负责向表单字段中使用的dataSearch对象添加值。

我个人会仔细检查EditProjAdminE组件是否接收到正确的dataSearch，然后在触发打开事件时调用类似于handleChange的函数。
