React AJAX

React component data may be obtained by componentDidMount method Ajax, while access to the database from the server can store data in the state, and then re-rendering method this.setState UI.

When using asynchronous data loading, unloading assembly before use componentWillUnmount to cancel outstanding requests.

The following example demonstrates Get latest gist Github users share Description:

var UserGist = React.createClass({
  getInitialState: function() {
    return {
      username: '',
      lastGistUrl: ''
    };
  },

  componentDidMount: function() {
    this.serverRequest = $.get(this.props.source, function (result) {
      var lastGist = result[0];
      this.setState({
        username: lastGist.owner.login,
        lastGistUrl: lastGist.html_url
      });
    }.bind(this));
  },

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

  render: function() {
    return (
      <div>
        {this.state.username} 用户最新的 Gist 共享地址：
        <a href={this.state.lastGistUrl}>{this.state.lastGistUrl}</a>
      </div>
    );
  }
});

ReactDOM.render(
  <UserGist source="https://api.github.com/users/octocat/gists" />,
  mountNode
);

try it"
