我有 2 个组件;一个市场,一个地位。状态组件管理用户拥有的金额,市场上有购买一些东西的按钮。当我点击按钮(在市场组件中)时,我希望我的钱减少。
我怎样才能以最好的方式实现这一目标?
这是我的具有市场和状态的应用程序组件:
import React from 'react';
import { Link } from 'react-router';
import { connect } from 'react-redux';
import { bindActionCreators } from 'redux';
import * as MarketActions from '../actions/market-actions';
import * as StatusActions from '../actions/status-actions';
import Market from './Market.react';
import Status from './Status.react';
export default class App extends React.Component {
render() {
const { dispatch, market, status } = this.props;
return (
<div>
<h1>App</h1>
<Link to='/'>App</Link>{' '}<Link to='/home'>Home</Link>
<Status status={status} {...bindActionCreators(StatusActions, dispatch)} />
<Market market={market} {...bindActionCreators(MarketActions, dispatch)} {...bindActionCreators(StatusActions, dispatch)} />
{this.props.children}
</div>
);
}
}
export default connect(state => ({ market: state.market, status: state.status }))(App);
我从市场组件的状态中绑定了操作(我觉得这不是正确的做法,但它确实有效)。
在此之后,我通过单击这样的按钮在 Market 组件中处理这些操作:
handleBuyClick(e) {
let { index, price } = e.target.dataset;
index = parseInt(index);
price = parseInt(price);
this.props.buyItem(index);
this.props.changeMoney(price); //this bugs me, i think it don't belongs there
}
有没有更好的办法?
谢谢
