    var _parseText=(text, flag)=> {
      console.log(flag)
      if (text.length > 200 && flag == true) {
        return text.substr(0, 200) + ' <a onClick={_parseText(text,false)}>Read More...</a>';
      } else {
        return text;
      }
    }

class DC extends React.Component {
    constructor(props) {
      super(props);
    }


    render() {
        return ( 
          <p dangerouslySetInnerHTML={{__html:_parseText('Lorem Ipsum is simply dummy text of the printing and typesetting industry.

将该功能放在组件外部并在没有它的情况下调用它。
