这是我迄今为止尝试过的

var Main = React.createClass({
    getInitialState:function(){
        return({
            user:[]
        });
    },
    addUser: function(loginToAdd) {
        this.setState({user: this.state.logins.concat(loginToAdd)});
    },
    render: function() {
        var abc = this.state.user.map(function(user){
            return(
                <Display user={user} key={user}/>
            );
        });
        return (
            <div>
                <Form addUser={this.addUser}/>
                {abc}
                <hr />
            </div>
        )
    }
});
var Form = React.createClass({
    handleSubmit: function(e) {
        e.preventDefault();
        var loginInput = React.findDOMNode(this.refs.login);
        this.props.addUser(loginInput.value);
        loginInput.value = '';
    },
    render:function(){
        return (
            <div onSubmit={this.handleSubmit}>
                <input type="text" placeholder="github login" ref="login"/>
                <button>Add</button>
            </div>
        )
    }
});
var Display = React.createClass({
    getInitialState:function(){
        return{};
    },
    componentDidMount:function(){
        var component = this;
        $.get("https://api.github.com/users/"+this.props.user,function(data){
            component.setState(data);
        });
    },
    render: function() {
        return (
            <div>
                <img src={this.state.avatar_url} width="80"/>
                <h1>{this.state.name}</h1>
            </div>
        )
    }
});
ReactDOM.render(<Main />, document.getElementById("app"));
