使用React.js顯示/隱藏模式不工作

Question

這裏是我的模態分量：

'use strict'; 

import React from 'react'; 

const Modal = React.createClass({ 
    handleOverlayClick() { 
     this.setState({ showModal: false }); 
    }, 

    shouldComponentUpdate (newProps, newState) { 
     return newState.showModal !== this.props.showModal; 
    }, 

    render() { 
     const style = { 
      display: (this.props.showModal) ? 'block' : 'none' 
     }; 

     console.log(style); 

     return (
      <div className="modal-overlay" style={style}> 
       <div className="modal-container" onClick={this.handleOverlayClick}> 
        <div className="modal-content modal-input">Hello, world</div> 
       </div> 
      </div> 
     ); 
    } 
}); 

module.exports = Modal; 

這是怎麼了稱之爲：

'use strict'; 

import React from 'react'; 
import ReactDOM from 'react-dom'; 
import SplitButton from './split-button'; 
import EmmaButton from './emma-button'; 
import SelectEmailModal from './modals/email-select.modal'; 

const AddActionBtn = React.createClass({ 

    onClick() { 
     return "#"; 
    }, 

    handleSendMailing() { 
     return ReactDOM.render(<SelectEmailModal showModal={true} />, document.getElementById('modals')); 
    }, 

    handleWait() { 
     console.log("WAIT"); 
     return "#"; 
    }, 

    render() { 
     return (
      <SplitButton primaryLabel="ADD ACTION &#9660;" primaryAction={this.onClick}> 
       <ul> 
        <li><span onClick={this.handleSendMailing}>Send mailing</span></li> 
        <li><span onClick={this.handleWait}>Wait</span></li> 
       </ul> 
      </SplitButton> 
     ); 
    } 
}); 

module.exports = AddActionBtn; 

我是一個福利局反應如此在這裏請原諒我的無知。只是想簡單地顯示/隱藏模式

Answer 1

也許錯誤在這裏？
display: (this.props.showModal) ? 'block' : 'none'

的ShowModal是一種狀態，而不是一個道具，所以： this.state.showModal
