【问题描述】:
这是我的代码
import React, { FC, InputHTMLAttributes, useEffect, useRef } from 'react';
type TElementType = HTMLInputElement | HTMLTextAreaElement;
type TElementWithAttributes = InputHTMLAttributes<HTMLInputElement>;
interface Props {
submitTouched: boolean;
}
const withInput = (Comp: FC<TElementWithAttributes>): FC<Props> => props => {
const { submitTouched } = props;
const refValue: React.RefObject<TElementType> = useRef(null);
const updateErrors = (val: string) => {
// handle errors
};
useEffect(() => {
if (submitTouched && refValue.current) {
updateErrors(refValue.current.value);
}
}, [submitTouched]);
const InputOrTextarea = (
<>
<Comp name="somename" type="text" value="somevalue" ref={refValue} />
</>
);
return InputOrTextarea;
};
export default withInput;
我在 ref={refValue} 上遇到错误
键入'{名称:字符串;类型:字符串;值:字符串;参考:参考对象; }' 不可分配给类型 'IntrinsicAttributes & TElementWithAttributes & { children?: ReactNode; }'。 类型'IntrinsicAttributes & TElementWithAttributes & { children?: ReactNode; 上不存在属性'ref' }'。
