问题 I have a form with one initial empty input field that I want to clone using a Add button and to remove with a Remove one. As it's not recommended to use index for the keys with dynamic forms, I tried to use uniqid module. But each time the state is updating, keys are renewed and I don't have unique data to identify each input of the form. I can add some items, but can't remove. input fields have no unique values, no id , how can I do ? const Form = () => { const update = e => {}; const items

问题 First of all, ive read this question React-redux connect() cannot wrap component defined as a class extending React.Component But im still unable to uderstand it since the connect is being done in some kind of upper level, but I dont understand that phase. This is my current structure: reduxStore.js import { createStore } from "redux"; import rootReducer from "../reducers/index"; const store = createStore(rootReducer); export default store; action-types.js export const RENDER_LAYOUT_ELEMENT =

问题 I am trying to fix a failing test in my react-redux app. When I dive and dive again into my component, I expect to see the JSX within it. However, I don't see anything. Here is my component - const Dashboard = (props) => { if (props.isSignedIn) return ( <div className="dashboard"> <h1>Welcome</h1> </div> ); return null; }; const mapStateToProps = (state) => { return { isSignedIn: state.auth.isSignedIn }; }; export default connect(mapStateToProps, { signIn, signOut })(Dashboard); Here is my

问题 I'm trying to show another component using the react-bootstrap modal and react state. I'm following a react-bootstrap modal code and trying to customize the state my own way. I am able to create the state to open the modal without using React.useStae. But the problem is the modal isn't closing when I click the close button. So, How can I fixe this problem with the state? This is the react-bootstrap modal code that I'm following: and this is my code where I'm trying to open another component

问题 I've attempted to create a kind of pattern-matching in typescript, particularly here for creating Redux reducers. I'd really like to be able to specify ahead of time that a reducer must handle all actions of a particular type. I've tried to do that by creating an object which is keyed by action type, with values which are reducers. The typings for this mapping looks like: export interface IReduxAction<T> { type: T; } interface IReducer<S, A> { (state: S, action: A): S; } export type

问题 I'm working on a task where I have to update a product images. Expo cache is posing a problem, when I update the product images and re-render the screen it does update my store state but doesn't show it. When I manually cleared expo cache it did work. I have also tried using the 'Cache-Control' header, but that didn't solve the problem. Is there a method I can call to clear expo cache ? 回答1: As far as I know the only way to clear Expo's cache is to add the -c flag to your expo start command.
