前端项目实战叁佰玖拾叁react-admin和material ui-react-hook-form 使用

import { useFormContext } from 'react-hook-form';

运行结果

const MyButton = () => {
    const { reset, setFocus, getValues } = useFormContext<{ step_no: string}>();
    useEffect(() => {
      setFocus('step_no');
    }, [setFocus]);
    return (
      <div style={{ marginTop: '10px' }}>
        <SaveButton type='button'
          label='保存'
          mutationOptions={{
            onSuccess: () => {
              reset({ step_no: (parseFloat(getValues('step_no')) + 1).toString() });
              window.scrollTo(0, 0);
              refresh();
              setFocus('step_no');
            }
          }}
        />
        <Button variant='contained' sx={{ ml: 2 }} onClick={() => {
          props.handleCreate&&props.handleCreate()
        }}>取消</Button>
      </div>
    )
  }

useFormContext

reset({ step_no: (parseFloat(getValues('step_no')) + 1).toString() }); 重新赋值
