後這裏如何再次渲染組件是我route.js網址變更

var Routes = (
    <Router history={hashHistory}> 
    <Route path="/" component={Authenticate}/> 
    <Route path="forgotpassword" component={ForgotPassword}/> 
    <Route path="resetpassword/:tokenId" component={ResetPassword}/> 
    <Route path="login" component={Login}/> 
    <Route path="loginaccount/:tokenId" component={DirectLogin}/> 
    <Route path="dashboard" component={UserBase}> 
     <IndexRoute component={Dashboard} /> 
     <Route path="changepassword" component={ChangePassword}/> 
    </Route> 
    <Route path='*' component={NotFound} /> 
    </Router> 
); 

所以,當我叫http://localhost:8080/#/dashboard的用戶羣和儀表板加載調用Ajax請求加載數據。在此之後,我將url更改爲http://localhost/#dashboard/changepassword它加載ChangePassword組件的一切都很好。

但是,當我返回到儀表板時,我的數據丟失了,它顯示空白的UI設計。

這裏是儀表板組件

var React = require('react'); 
import Grid from "./DashboardGrid.js"; 
import PopupOver from '../common/PopupOver.js'; 
import Loader from '../common/Loader.js'; 
import ListBox from "../common/ListBox.js"; 
import Auth from "../common/Cookies.js"; 
import LoadFile from '../common/LoadFile.js'; 
import ERRORS from '../common/Errors.js'; 
import Const from '../constants/Constants'; 
import ErrorMessage from '../constants/ErrorMessage'; 
import LINK from '../constants/LinkConstants'; 

var Router = require('react-router'); 

class Dashboard extends React.Component{ 

    constructor(){ 
     console.log("called..dashboard") 
     super(); 
     this.tab2Chart = 0; 
     this.state = {typeData:'-1', lastPeriod:'2', gridData:[], graphLoad:false, showLoader:false} 
    } 

    componentWillReceiveProps(nextProps) { 
     console.log(nextProps) 
     if (nextProps.gridData !== this.props.gridData) { 
      this.setState({gridData:nextProps.gridData, typeData:'-1', lastPeriod:'2',}); 
      this.datePicker(2); 

     } 
    } 


    render(){ 

     var entryData = this.state.gridData; //grid data 
     var placementData = this.props.placementData; //dropdown data 

     var tab3 = 0; 
     var tab4 = 0; 
     var tab2 = 0; 
     var tab0 = 0; 
     var tab1 = 0; 
     var fromdate; 
     var rows = entryData.map(function(eachRow) { 
      for (var key in eachRow){ 
       var comment = eachRow[key]; 
       tab3 = tab3 + comment.tab3; 
       tab4 = tab4 + comment.tab4; 
       tab2 = tab2 + comment.tab2; 
      } 
     }); 

     if(tab3 && tab2){ 
      tab0 = parseFloat(tab2/tab3); 
     } 

     if(tab4 && tab2){ 
      tab1 = (tab2/tab4)*1000 
     } 

     var lastPeriod = [ 
      {name: "Today",value:"0"}, 
      {name: "Yesterday",value:"1"}, 
      {name: "Last 7 Days",value:"2"}, 
      {name: "Last 30 Days",value:"3"}, 
      {name: "This Month",value:"4"}, 
      {name: "Last Month",value:"5"}, 
      {name: "Last Year",value:"6"} 
     ] 

     var list = []; 
     placementData.forEach(function(data){ 
      var k = {name:data.ad_title, value:data.id}; 
      list.push(k); 
     }); 

     return (

      <div> 
      {this.state.showLoader? <Loader show='true'/> : <Loader show='false'/>} 

      <div className="right_col" role="main"> 
       <div className="row tile_count"> 
       <div className="col-md-2 col-sm-4 col-xs-6 tile_stats_count"> 
        <span className="count_top">Revenue</span> 
        <div className="count green"><i className="fa fa-dollar"/><div className='displayinline'>{numberWithCommas(tab2)}</div></div> 
       </div> 
       <div className="col-md-2 col-sm-4 col-xs-6 tile_stats_count"> 
        <span className="count_top">Impressions</span> 
        <div className="count">{numberWithCommas(tab4)}</div> 
       </div> 
       <div className="col-md-2 col-sm-4 col-xs-6 tile_stats_count"> 
        <span className="count_top">Total Clicks</span> 
        <div className="count">{numberWithCommas(tab3)}</div> 
       </div> 
       <div className="col-md-2 col-sm-4 col-xs-6 tile_stats_count"> 
        <span className="count_top">Net PPC</span> 
        <div className="count"><i className="fa fa-dollar"/><div className='displayinline'>{numberWithCommas(tab0)}</div></div> 
       </div> 
       <div className="col-md-2 col-sm-4 col-xs-6 tile_stats_count"> 
        <span className="count_top">Net eCPM</span> 
        <div className="count"><i className="fa fa-dollar"/><div className='displayinline'>{numberWithCommas(tab1)}</div></div> 
       </div> 
       </div> 


          <div className="item"> 
           <div className="x_content"> 
           <div className="table-responsive"> 
            <Grid items={entryData}/> 
           </div> 
           </div> 
          </div> 
      <div className="clearfix"></div> 
     </div> 
</div> 
     ); 
    } 
} 

export default Dashboard; 

所以在上面的代碼TAB1被變爲0時,網址爲返回回來。我在反應週期中錯過了什麼?

如果任何其他代碼需要請告訴我..

如果有儀表板的需求,我認爲這將是更好地使Ajax調用每當儀表板安裝,componentWillMount儀表板類內的特定數據也許是這個的好地方。
