如何使redux-form与TypeScript和styled-components一起工作?


我正在尝试让redux-form与TypeScript和Styled-Components一起工作。在下面的代码示例中,为什么它不能与样式化的输入组件一起工作?输入呈现出来,但每个按键都失去了焦点。还需要单击两次来聚焦元素。看起来redux-form试图控制Styled-Components返回的包装元素?redux-form和styled-components都使用HOC高阶组件将道具传递给底层元素。

export interface ITxtProps extends WrappedFieldProps {
  label?: string;
}

export const FieldHack = class extends Field<any> {};

const renderTxt = (props: ITxtProps & GenericFieldHTMLAttributes) => {
  const StyledInput = styled.input`
    background-color: deeppink;
  `;
  const notWorking = <StyledInput {...props.input} />;
  const worksPerfectly = <input {...props.input} />;
  return (
  <div>
    <div>{props.label}</div>
    {notWorking}
  </div>
);
}

const NormalLoginComponent = (props: {
  handleSubmit?: SubmitHandler<{}, {}>;
}) => {
  const { handleSubmit } = props;
  return (
    <form onSubmit={handleSubmit}>
      {/* this does not work when using styled components: */}
      <Field name={'email'} component={renderTxt}  />

      {/* this gives an error, property label does not exist on type... */}
      {/*<Field name={'email'} component={renderTxt} label="email" />*/}

      {/* this works, but no intellisense/static types */}
      <FieldHack name={'email2'} component={renderTxt} label="email" />

      <Field name={'password'} component={'input'} type="password" />
      <Button text={'log in'} onClick={handleSubmit} />
    </form>
  );
};

export interface ILoginForm {
  email: string;
  password: string;
}

const LoginForm = reduxForm<Readonly<ILoginForm>, {}>({
  form: 'loginNormal',
})(NormalLoginComponent);

是的,我终于想通了..我犯了一个错误,那就是在render方法中创建了样式化组件包装:

const StyledInput = styled.input`
  background-color: deeppink;
;

显然,在render()中应用一个hoc-high-order组件是不安全的。因此当将HOC移到外部呈现时,它应该可以工作:

export interface ITxtProps extends WrappedFieldProps {
  label?: string;
}

export const FieldHack = class extends Field<any> {};

// wrap you HOC outside render:
const StyledInput = styled.input`
    background-color: deeppink;
  `;

const renderTxt = (props: ITxtProps & GenericFieldHTMLAttributes) => {
  // works now :)
  const notWorking = <StyledInput {...props.input} />;
  const worksPerfectly = <input {...props.input} />;
  return (
  <div>
    <div>{props.label}</div>
    {notWorking}
  </div>
);
}

我在阅读另一个HOC库的文档时弄清楚了这一点,这里有一个链接解释了在HOC上应用(任何)HOC:redux-auth-wrapper文档是安全的
