用法
alertTitle 弹框标题
alertTip 弹框内容,样式自己自定义
closeAlert 关闭时候返回信息,可要可不要,根据自己需求。
import Toptips from "./Toptips" Toptips.open({ alertTitle: '批示详情', alertTip: that.htms(val), closeAlert: function () { console.log("关闭了..."); } }); htms = val => { return (<div className="alert-detais-list"> <div className="alert-detais-list-C"> <p>批示内容:</p> <p>{val.fdTitle}</p> </div> <div className="alert-detais-list-C"> <p>批示详述:</p> <p>{val.fdTitle}</p> </div> <div className="alert-detais-list-C"> <p>措施及结果:</p> <p>{val.fdContent}</p> </div> <div className="alert-detais-list-C"> <p>进度详情:</p> <p></p> </div> </div>) }
