react-router

问题 I have a component that has props which extend RouteComponentProps that looks like this: export interface RouteComponentProps<P> { match: match<P>; location: H.Location; history: H.History; staticContext?: any; } Now, when I use my component in the app, I pass these props to it: <MyComponent match={this.props.match} location={this.props.location} history={this.props.history} /> The props are available already because it's running inside react router. Now, how do I test this component without

问题 I have need to pass a value from a page to another using react-router.

问题 The Terminal failed to compile. because create is not defined, I still learn using routers , it seems that the syntax or the locations wrong, I tried to understand how should I write it right in this project but there are too many details in my code already.

问题 My app has multiple pages labelled 'Red', 'Green', 'Blue' and 'Pink'. To allow the user to navigate between the pages, I use React Router (v5.2.0). The routes are wrapped in a TransitionGroup (v4.4.1) so that when the user navigates to a new page, a fade-in transition effect is applied to the page that makes it slowly fade into view. The duration of this transition is 5000ms. **Problem** The app initialises on page 'Red'. Say the user clicks on page 'Blue' and then on page 'Pink' while Blue's

This is my js file that I created with exporting functions export function BackgroundMove() { $(document).ready

问题 I have a parent component called EnrollForm with a BrowserRouter that routes to different sub-components which are the pages of my overall EnrollForm. Each time a sub-component page is filled out and next btn is clicked, all form fields are saved to sub-component state obj, then that state is passed to the parent EnrollForm state. This flow is working correctly.. however when I added the line of code to href to the next sub-component, the parent EnrollForm state is deleted and so is BioForm's
