在父组件中使用

 <Editor 
            getContent={this.getRichConditions}
            verified={!disabled}
            title={'申报条件'}
            content={richConditions}    // string 编辑器内容
            tips={this.state.conditionTips}
            articleFlag={this.state.richFlag}   // 是否回填内容  
            width={100}
            height={293}
            boxWidth={'boxWidth'}
       />

  // 富文本框
    getRichConditions=(aa, bb)=>{
        // 申报条件
        this.setState({
            richConditions: aa,
            conditionTips: bb,   // 正文错误提示 bool
            richFlag: false
        });
    }
