在React Native中使用Redux时,找不到变量addProduct错误可能是由以下几个原因引起的:
import { createStore, combineReducers } from 'redux';
import { Provider } from 'react-redux';
const productReducer = (state = [], action) => {
switch (action.type) {
case 'ADD_PRODUCT':
return [...state, action.payload];
default:
return state;
}
};
const rootReducer = combineReducers({
products: productReducer,
});
const store = createStore(rootReducer);
import { connect } from 'react-redux';
const MyComponent = ({ products, addProduct }) => {
// 使用products和addProduct变量
// ...
};
const mapStateToProps = (state) => ({
products: state.products,
});
const mapDispatchToProps = (dispatch) => ({
addProduct: (product) => dispatch({ type: 'ADD_PRODUCT', payload: product }),
});
export default connect(mapStateToProps, mapDispatchToProps)(MyComponent);
以上是一些可能导致在React Native中使用Redux时找不到变量addProduct错误的常见原因和解决方法。如果问题仍然存在,请提供更多的代码和错误信息,以便更好地帮助解决问题。
