前端项目实战叁佰零玖react-admin+material ui-react-admin-admin中SimpleFormIterator之reOrderButtons

    const { index, total, reOrder } = useSimpleFormIteratorItem();

    return (
        <>
            <IconButton
                size="small"
                onClick={() => reOrder(index - 1)}
                disabled={index <= 0}
            >
                <ArrowUpwardIcon />

            <IconButton
                size="small"
                onClick={() => reOrder(index + 1)}
                disabled={total == null || index >= total - 1}
            >
                <ArrowDownwardIcon />
            </IconButton>
        </>
    );
};

const OrderEdit = () => (

        <SimpleForm>
            <TextInput source="customer" />
            <DateInput source="date" />
            <ArrayInput source="items">
                <SimpleFormIterator reOrderButtons={<ReOrderButtons />}>
                    <TextInput source="name" />
                    <NumberInput source="price" />
                    <NumberInput source="quantity" />
                </SimpleFormIterator>
            </ArrayInput>
        </SimpleForm>
