react-router与react-redux跳转后保存store数据(基于"react-router": "^2.8.0")
1.router引入
import { Route, IndexRoute, Router, hashHistory, browserHistory } from 'react-router';
<Router routes={routes} history={browserHistory}/>
假设store结构如下,分别是主页home,详情页detail,评论页comment
{
comment: {
comments:[],
leng:0
}
detail: {
content: "xxx"
}
home: {
loading: false,
pos: 0,
stories: []
}
}
2.在主页home跳到详情页detail时,在主页实现获取详情页的请求数据,并赋予store,这样store就保留home,
//在home里面跳转是触发fetchDetailData
<Link to={ '/detail/'+item.id} onClick={this.props.fetchDetailData.bind(this,item.id) }>
获取完详情数据后,这样store数据就成以下结构
{
comment: {
comments:[]
leng:0
}
detail: {
content:"xxx"
}
home: {
loading:false
pos:29228
stories:Array(201)
}
}
3.在详情页detail跳到评论页comment时,在详情页detail实现获取评论页comment的请求数据,并赋予store,这样store就保留home,detail的数据了
//在详情页detail里面跳转是触发fetchCommentData
<Link to={ '/comment/'+this.articleId} onClick={this.props.fetchCommentData.bind(this, this.articleId) }>评论</Link>
获取完评论数据后,这样store数据就成以下结构
{
comment: {
comments:Array(20)
leng:20
}
detail: {
content:"xxx"
}
home: {
loading:false
pos:29228
stories:Array(201)
}
}
4.这样,当要返回是时还原状态就可以从本地缓存的store里面取数据渲染。
//在返回主页home时,在主页做判断,回到最初的最初点击跳转时的位置 componentDidMount () { if(this.props.stories.length === 0 ){ this.props.fetchHomeData(this.s) }else{ console.log(this.props.route.component.displayName) if(this.props.route.component.displayName == "Connect(Home)"){ window.scrollTo(0,this.props.pos); } this.s() } }
