React——State

状态管理机制==？vuex?

就教程来看，还是不一样的，相当于vue实例里的data初始化，methods事件处理

var LikeButton = React.createClass({
    getInitialState: function() {    //state
      return {liked: false};
    },
    handleClick: function(event) {
      this.setState({liked: !this.state.liked});
    },
    render: function() {
      var text = this.state.liked ? '喜欢' : '不喜欢';
      return (
        <p onClick={this.handleClick}>你<b>{text}</b>我。点我切换状态。</p>
      );
    }
});
ReactDOM.render(
  <LikeButton />,
  document.getElementById('app')  
);
