React JSX Question

populate select with datajson using React js

I'm trying to populate a select using React js, I'm using the example given on the react js docs(https://facebook.github.io/react/tips/initial-ajax.html) , which uses jquery to manage the ajax calling, I'm not able to make it work, so far i have this:

here the codepen : http://codepen.io/parlop/pen/jrXOWB

//json file called from source : [{"companycase_id":"CTSPROD","name":"CTS-Production"},{"companyc ase_id":"CTSTESTING","name":"CTS-Testing"}]
//using jquery to make a ajax call
var App = React.createClass({
getInitialState: function() {
return {
opts:[]
};
},

componentDidMount: function() {
var source="https://api.myjson.com/bins/3dbn8";
this.serverRequest = $.get(source, function (result) {
var arrTen = result[''];
for (var k = 0; k < ten.length; k++) {
arrTen.push(<option key={opts[k]} value={ten[k].companycase_id}> {ten[k].name} </option>);
}

}.bind(this));
},

componentWillUnmount: function() {
this.serverRequest.abort();
},

render: function() {
return (
<div>
<select id='select1'>
{this.state.opts}
</select>
</div>
);
}
});

ReactDOM.render(
<App />,
document.getElementById('root')
);


html

<div id="root"></div>


any idea how to make it works, thanks.

Answer

You need to call setState to actually update your view. Here's a workable version.

//json file called from source : [{"companycase_id":"CTSPROD","name":"CTS-Production"},{"companyc  ase_id":"CTSTESTING","name":"CTS-Testing"}]
//using jquery to make a ajax call
var App = React.createClass({
getInitialState: function() {
    return {
      opts:[]      
    };
},

componentDidMount: function() {
  var source="https://api.myjson.com/bins/3dbn8";
  this.serverRequest = $.get(source, function (result) {
    var arrTen = [];
    for (var k = 0; k < result.length; k++) {
        arrTen.push(<option key={result[k].companycase_id} value={result[k].companycase_id}> {result[k].name} </option>);
    }
    this.setState({
      opts: arrTen
    });
  }.bind(this));
},

  componentWillUnmount: function() {
  this.serverRequest.abort();
},

render: function() {
  return (
    <div>        
      <select id='select1'>
        {this.state.opts}
      </select>
    </div>
  );
 }
});

ReactDOM.render(
   <App />,
  document.getElementById('root')
);
