我尝试使用React js填充选择,我使用react js docs(https://facebook.github.io/react/tips/initial-ajax.html)上给出的示例,它使用jquery来管理ajax调用,我&# 39;我无法使它工作,到目前为止,我有这个:
这里是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>
任何想法如何使其有效,谢谢。

您需要调用setState来实际更新视图。这是一个可行的版本。
//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')
);
