如何使 redux-form 与 TypeScript 和样式组件一起工作?
How to make redux-form work with TypeScript and styled-components?
我正在尝试让 redux-form 与 TypeScript 和样式组件一起使用。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使用?输入呈现,但焦点在每次按键时丢失。还需要单击两次才能聚焦元素。似乎 redux-form 试图控制从 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,那就是在渲染方法中创建我的样式组件包装器:
const StyledInput = styled.input`
background-color: deeppink;
;
显然在 render() 中应用 HOC - 高阶组件是不安全的。所以它应该在将 HOC 移出渲染时起作用:
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>
);
}
我正在阅读另一个 HOC 库的文档来解决这个问题,这里有一个 link 解释了在哪里可以安全地应用(任何)HOC:redux-auth-wrapper documentation on HOCs
