我是使用React的新手,并且正在尝试将DraftJS与React和Redux集成。 我收到有关传递道具的错误消息,但不确定为什么没有传递道具。 所以我想更大的问题是如何使DraftJS能够运行React和Redux,而更直接的问题是此错误消息。
这是我收到的错误消息
warning.js:33 Warning: Failed prop type: Invalid prop `component` of type `object` supplied to `Route`, expected `function`.
in Route (created by AppRouter)
in AppRouter
in Provider
这是AppRouter文件
import React from 'react';
import { Router, Route, Switch } from 'react-router-dom';
import createHistory from 'history/createBrowserHistory'
import PostsIndex from '../components/posts/PostsIndex';
import PostNew from '../components/posts/PostNew';
import PostEdit from '../components/posts/PostEdit';
import PostShow from '../components/posts/PostShow';
export const history = createHistory();
const AppRouter = () => (
<Router history={history}>
<div>
<Switch>
<Route path="/" component={PostsIndex} exact={true} />
<Route path="/posts/new" component={PostNew} exact={true} />
<Route path="/posts/:id/edit" component={PostEdit} exact={true} />
<Route path="/posts/:id" component={PostShow} exact={true} />
</Switch>
</div>
</Router>
);
export default AppRouter;
这是Posts Reducer文件
import { EditorState } from 'draft-js';
const defaultState = {
editorState: EditorState.createEmpty(),
};
const postsReducer = (state=defaultState, action) => {
console.log('redux action: ', action.payload);
switch(action.type){
case 'START_ADD_POST':
return {
...state,
action
}
default:
return state
}
};
export default postsReducer;
postsReducer中的console.log向我显示了这个
PostNew {props: undefined, context: undefined, refs: {…}, updater: {…}}
这是帖子操作文件
export const startAddPost = (editorState) => ({
type: 'START_ADD_POST',
editorState
});
这是商店文件
import { createStore, combineReducers } from 'redux';
import postsReducer from '../reducers/posts';
export default () => {
const store = createStore(
combineReducers({
posts: postsReducer
})
);
return store;
};
这是NewPost组件
import React from 'react';
import { connect } from 'react-redux';
import { startAddPost } from '../../actions/posts';
import PostForm from './PostForm';
export class PostNew extends React.Component {
render() {
return (
<div>
<h1>New Post</h1>
<PostForm />
</div>
)
}
}
const mapStateToProps = (state) => {
console.log("state", state);
return {
post: state
}
}
const mapDispatchToProps = (dispatch) => ({
startAddPost: (editorState) => dispatch(startAddPost(post))
});
export default connect(mapStateToProps, mapDispatchToProps)(PostNew);
console.log('PostNew', new PostNew());
这是PostNew上的console.log返回的内容
state
{posts: {…}}

这是PostForm组件
import React from 'react';
import {Editor, EditorState} from 'draft-js';
export default class PostForm extends React.Component {
constructor(props) {
super(props);
this.state = {editorState: EditorState.createEmpty()};
this.onChange = (editorState) => this.setState({editorState});
}
render() {
return (
<Editor editorState={this.state.editorState} onChange={this.state.onChange} />
)
}
}
