  this.getComments();

  setInterval() => this.getComment,500;

 

}

handleCommnetSubmit(comment) {

  let comments = this.state.dta,

    newComments = comments.concat(comment);

  this.setState({data:newComment});

}

getComments() {

 

$.ajx({

    url:this.props.url,

    dataType:‘json‘,

    cache: false,

    success:comments => {

      this.setState(data:comments);

    },

    error:(xhr,status, error) =>{

 

    }

  })

}

  render() {

    <div className="ui comments">

      <h1>评论</h1>

      <div className="ui divider">

        <CommentList data={this.state.data} />

}
