const { Modal, Button } = antd;class App extends React.Component {  state = {    loading: false,    visible: false,  }  render() {    const { visible, loading } = this.state;    return (      
    
               
     
      ,            
                      Submit              ,          ]}        >                 
           
    
    );  }}ReactDOM.render(
    , mountNode);复制代码

或者是使用Modal.info方法等 提示方式 Modal.info({    title: 'This is a notification message',    content: (      
    
        
     
some messages...some messages...
        
     
some messages...some messages...
      
    
    ),    onOk() {},  });复制代码
