javascript - 单击任何菜单项时如何关闭汉堡菜单

问题描述

单击菜单项时，我想关闭菜单框。

选中某个样式运行时会出现一个输入字段，而未选中时样式会消失。react router创建的item menu的链接（单页应用）

我不能使用 jquery。

import React from 'react';
import { Link } from 'react-router-dom'
import logoNoFrame from '../Assets/img/logo_noFrame.svg'

const Header = ({
  menuItems,
}) => {
  return (
    <header >
      <div className="logoAnimated">
        <Link to="/"><img src={logoNoFrame} alt="Logo" /></Link>
      </div>

最大宽度的开始菜单：700px；

<ul className="menu">
  {menuItems.map(item => {
    return item.isActive && <li key={item.id}>
      <Link to={item.menuAddress}>
        <i className={item.menuClasses}></i>
        <span style={{ whiteSpace: "nowrap" }}>{item.menuTitle}</span>
      </Link>
    </li>
  })}
</ul>

最小宽度的启动汉堡菜单：700px；

<input id="toggle" type="checkbox" />
<label className="toggle-container" htmlFor="toggle">
  <span className="button button-toggle"></span>
</label>
<nav className="nav">
  {menuItems.map(item => {
    return item.isActive &&
      <Link
        key={item.id}
        className="nav-item"
        to={item.menuAddress}
      >
        {item.menuTitle}
    </Link>
  })}
</nav>

最小宽度的结束汉堡菜单：700px；

    </header>
  );
};

export default Header;

解决方案

我找到了我的答案。我在标签标签上设置了 onClick 来运行 closeMenu 函数。我还将 checkInput 设置为状态并使用更改输入进行修复:)

import React from 'react';
import { Link } from 'react-router-dom'

import logoNoFrame from '../Assets/img/logo_noFrame.svg'

class Header extends React.Component {
  state = {
    menuItems: {},
    checkInput: false,
  }

  closeMenu = () => {
    const checkInput = this.state.checkInput
    this.setState (prevState => {
      return {
        ...prevState,
        checkInput: !checkInput
      }
    })
  }

  render(){
    const { menuItems } = this.props

    return (
      <header>
        <div className="logoAnimated">
          <Link to="/">
            <img src={logoNoFrame} alt="Logo" />
          </Link>
        </div>
        <ul className="menu">
          {menuItems.map(item => {
            return item.isActive && 
              <li key={item.id}>
                <Link to={item.menuAddress}>
                  <i className={item.menuClasses}></i>
                  <span style={{ whiteSpace: "nowrap" }}> 
                     {item.menuTitle}
                  </span>
                </Link>
              </li>
            }
          )}
        </ul>
        <input
          id="toggle"
          type="checkbox"
          checked={this.state.checkInput}
        />
        <label 
          className="toggle-container"
          onClick={this.closeMenu}
        >
          <span className="button button-toggle"></span>
        </label>
        <nav className="nav">
          {menuItems.map(item => {
            return item.isActive &&
              <Link
                key={item.id}
                className="nav-item"
                to={item.menuAddress}
                onClick={this.closeMenu}
              >
                {item.menuTitle}
              </Link>
          })}
        </nav>
      </header>
    );
  }
};

export default Header;
