Question

我是React的新手，我想在点击后隐藏一个按钮。下面的两个代码段下面是proptypes。我需要一个hideSubmit按钮吗？单击后如何隐藏按钮？我读到我可以通过州或CSS来做到这一点。既然这是一个按钮，它似乎更容易使用CSS？任何帮助将不胜感激。

import React, { Component } from 'react';
import PropTypes from 'prop-types';
import todoStyle from 'src/style/todo-style.scss';
import { Router, Route, hashHistory as history } from 'react-router';
import Myaccount from 'src/components/myaccount.jsx';

export default class Headermenu extends Component {

  constructor(){
  super();

  // Initial state
  this.state = { open: false };

}

toggle() {
  this.setState({
    open: !this.state.open
  });
}

  componentdidMount() {
    this.menuclickevent = this.menuclickevent.bind(this);
    this.collapse = this.collapse.bind(this);
    this.myaccount = this.myaccount.bind(this);
    this.logout = this.logout.bind(this);
  }

  render() {
    return (
      <div>

        <div style={{ textAlign: 'center', marginTop: '10px' }} id="menudiv" onBlur={this.collapse}>
          <button onClick={this.toggle.bind(this)} > Menu </button>

          <div id="demo" className={"collapse" + (this.state.open ? ' in' : '')}>
            <label className="menu_items" onClick={this.myaccount}>MyAccount</label>
            <div onClick={this.logout}>
              Logout
            </div>
          </div>

        </div>
      </div>
    );
  }

  menuclickevent() {
    const listmenu = document.getElementById('listmenu');
    listmenu.style.display = 'block';
  }



  logout() {
    console.log('Logout');
  }
  myaccount() {
    history.push('/myaccount');
    window.location.reload();
