只是一个免责声明 - 当我的主要组件中存在有问题的功能时,我的代码才有效。在我导出它之后它停止了它的行为。我的理论是因为道具不能正确更新。
无论如何,我有一个组件,在点击之后它开始监听窗口对象并将正确的存储元素设置为" true"并根据下一个对象点击相应的行为。单击不正确的对象后,商店应该恢复为false,但它确实存在,但道具仍然是" true"如下面的截图所示。
我该如何解决这个问题?也许有一种方法,函数可以将存储作为参数而不是道具?或者我正确地称行动或者完全错过了什么?
以下代码:
主要组成部分(相关部分?):
import React from 'react';
import { connect } from 'react-redux'
import { bindActionCreators } from 'redux'
import {activate} from '../../actions/inventory'
import { setModalContent, setModalState } from '../../actions/modal';
import inventoryReducer from '../../reducers/inventory';
import {chainMechanics} from './itemMechanics/chainMechanics';
class ItemRenderer extends React.Component{
handleBoltcuttersClicked(){
this.props.activate('boltcutters', true);
setTimeout(() => chainMechanics(this.props), 100)
}
inventoryItemRender(){
let inventoryItem = null;
if(this.props.inventory.items.boltcutters){
inventoryItem = <a className={this.props.inventory.activeItem.boltcutters ? "ghost-button items active " : "ghost-button items"} href="#" id='boltcuttersId' onClick={() => this.handleBoltcuttersClicked()}>Boltcutters</a>
}
return inventoryItem;
}
render(){
let renderItems = this.inventoryItemRender();
return(
<div>
{renderItems}
</div>
)
}
}
const mapStateToProps = (state) => {
return {
level: state.level,
inventory: state.inventory
}
}
function mapDispatchToProps(dispatch) {
//dispatch w propsach
return(
bindActionCreators({activate: activate, setModalState: setModalState, setModalContent: setModalContent }, dispatch)
)
}
export default connect(mapStateToProps, mapDispatchToProps)(ItemRenderer);
有问题功能的文件:
import {activate} from '../../../actions/inventory'
import { setModalContent, setModalState } from '../../../actions/modal';
export function chainMechanics(props){
let clickedElement;
window.onclick = ((e)=>{
console.log(clickedElement, 'clickedelement', props.inventory.activeItem.boltcutters)
if(props.inventory.activeItem.boltcutters===true){
clickedElement = e.target;
if(clickedElement.id === 'chainChainedDoor'){
props.activate('boltcutters', false);
props.setModalContent('Chain_Broken');
props.setModalState(true);
} else if(clickedElement.id === 'boltcuttersId'){
console.log('foo')
} else {
props.activate('boltcutters', false);
props.setModalContent('Cant_Use');
props.setModalState(true);
console.log("props.inventory.activeItem.boltcutters", props.inventory.activeItem.boltcutters);
}
}
})
}
我的行动:
const inventoryReducer = (state = inventoryDefaultState, action) => {
switch (action.type) {
case 'ACTIVE':
console.log(action)
return {
...state,
activeItem: {
...state.activeItem,
[action.item]: action.isActive
}
}
default:
return state;
}
}
我如何配置商店:
export default () => {
const store = createStore(
combineReducers({
level: levelReducer,
modal: modalReducer,
inventory: inventoryReducer,
styles: stylesReducer
}),
applyMiddleware(thunk)
)
return store;
}
我认为需要进行传送吗?如果不是,请让我知道,我一直试图让这项工作很长时间。
答案 0 :(得分:0)
您可以使用React的功能componentWillReceiveProps
。这将触发这样的重新渲染(并且还使用下一个道具/州):
componentWillReceiveProps(next) {
console.log(next);
this.inventoryItemRender(next);
}
inventoryItemRender(next){
const inventory = next.inventory ? next.inventory : this.props.inventory;
let inventoryItem = null;
if(inventory.items.boltcutters){
inventoryItem = <a className={inventory.activeItem.boltcutters ? "ghost-button items active " : "ghost-button items"} href="#" id='boltcuttersId' onClick={(next) => this.handleBoltcuttersClicked(next)}>Boltcutters</a>
}
return inventoryItem;
}
handleBoltcuttersClicked(props){
this.props.activate('boltcutters', true);
setTimeout(() => chainMechanics(props), 100)
}
