渲染的任何更改都应通过
state或
props（react
doc）进行更改。
因此，在这里我注册了输入事件，然后更改了
state，这将触发呈现在页脚上的渲染。
var SearchResult = React.createClass({ getInitialState: function () { return { site: '', address: '' }; }, onSiteChanged: function (e) { this.setState({ site: e.currentTarget.value }); }, onAddressChanged: function (e) { this.setState({ address: e.currentTarget.value }); }, render: function(){ var resultRows = this.props.data.map(function(result){return ( <tbody> <tr> <td><input type="radio" name="site_name" value={result.SITE_NAME} checked={this.state.site === result.SITE_NAME} onChange={this.onSiteChanged} />{result.SITE_NAME}</td> <td><input type="radio" name="address" value={result.ADDRESS} checked={this.state.address === result.ADDRESS} onChange={this.onAddressChanged} />{result.ADDRESS}</td> </tr> </tbody>); }, this); return (<table className="table"> <thead> <tr> <th>Name</th> <th>Address</th> </tr> </thead> {resultRows} <tfoot> <tr> <td>chosen site name {this.state.site} </td> <td>chosen address {this.state.address} </td> </tr> </tfoot></table> ); }});jsbin
