はのsObjectのリストがコントローラ

Question

私は componentWillMount方法

componentWillMount() 
    { 
    this.props.dispatch(qryAccts()); 
    console.log(this.props); 
    } 

からリモートアクション（Salesforceの機能）を呼び出しています

からリストを取得した後に表示されていないのJSを反応させ、自分の行動が

export function qryAccts() 
{ 
    return dispatch => { 
    ResponsiveCtrl.getAccts(function(r, e) { 
     console.log('------26----',r); 
     dispatch(recAccts(r)) 
    },{escape:false}); 
    } 
} 

でありますこの行はありません26オブジェクトのリストを取得していますが、私のDOMにはこのページが表示されません

render() { 
    return (
     <div> 
     <h1>Accounts</h1> 
     <ul> 
     {this.props.accts && this.props.accts.map((v,i) => <li key={i}><input style={{width:'500px'}} onChange={event => this.handleChange(event,i)} value={v.Name}/></li>) } 
     </ul> 
     </div> 
    ); 
    } 

ここで何が問題なのでしょうか。

/* This is a thunk, meaning it is a function that immediately

    NOTE: This is solely for demonstration purposes. In a real application, 
    you'd probably want to dispatch an action of COUNTER_DOUBLE and let the 
    reducer take care of this logic. */

    //Perform Upsert Actions 
    upsertAccts(e) 
    { 
    this.props.dispatch(upsertAccts(this.props.accts)) 
    } 

    //Add new Account to the Array 
    addAcct(event) 
    { 
    this.props.dispatch(addAcct()); 
    console.log('===this.props===',this.props); 
    } 


    //onChange function to handle when a name is changed 
    handleChange(ev,index) 
    { 
    this.props.dispatch(updateAccts(ev.target.value,index)); 
    } 

    dateChange(e) 
    {

export default connect(state => ({ accts: state.accts }))(HomeView); 

Answer 1

あなたはここにstate = action.accts;、ここnewState[action.listIndex].Name = action.acctName減速内の状態を変更しています。

これはおそらくあなたの問題です。

そうでない場合は、redux-devtoolsを使用して、新しいオブジェクトが実際に状態に保存されていることを確認してください。次に、react devtoolsを使用して、正しいデータがHomeView
