reactjs - 当我使用 Link 或 NavLink 导航到 React 组件时，我的 Materialize css sidenav 汉堡菜单不起作用

问题描述

在移动视图上，每当我使用 Link 或 NavLink 导航到 React 组件并且浏览器不刷新我的物化 css sidenav 汉堡菜单时，我的实体化 css sidenav 汉堡菜单将变得静止且不可点击，但是当我重新加载页面时，sidenav 汉堡菜单将再次变为可点击。我知道这对我的移动用户来说不是一个好的用户体验。我已经尝试使用锚标记，但是如果每次单击浏览器都会重新加载，那么构建单页应用程序的目的就会失败。任何帮助、线索或建议将不胜感激。这是我尝试过的：

导航栏.js

import React from 'react'
import {Link} from 'react-router-dom'
import '../../myStyles/main.css' //my custom css file


const Navbar = () => {
    return (
        <div>
        <nav className="link-nav">
            <div className="nav-wrapper">

            <ul className="center hide-on-med-and-down">
                <li><Link className="link-font-size" to='/'>HOME</Link></li>
                <li><Link className="link-font-size" to='/about'>About</Link></li>
                <li><Link className="link-font-size" to='/contact'>Contact</Link></li>
                <li><Link className="link-font-size" to='/login'>Login</Link></li>
                <li><Link className="link-font-size" to='/signup'>Sign Up</Link></li>
            </ul>
            </div>
        </nav>

        <ul id='mobile-sidenav-menu' className="sidenav">

                <li><Link className="link-font-size" to='/login'>Login</Link></li>
                <li><Link className="link-font-size" to='/signup'>Sign Up</Link></li>
         </ul>
          <a to="#" className="sidenav-trigger" data-target="mobile-sidenav-menu" >
                <i className="material-icons">menu</i>
            </a>
        </div>
    )
}

export default Navbar

解决方案

根据materializecss docs，将汉堡包放在导航栏中是否有帮助？

<nav className="link-nav">
     <div className="nav-wrapper">
        <a to="#" className="sidenav-trigger" data-target="mobile-sidenav-menu" ><i className="material-icons">menu</i></a>
        <ul className="center hide-on-med-and-down">
            <li><Link className="link-font-size" to='/'>HOME</Link></li>
            <li><Link className="link-font-size" to='/about'>About</Link></li>
            <li><Link className="link-font-size" to='/contact'>Contact</Link></li>
            <li><Link className="link-font-size" to='/login'>Login</Link></li>
            <li><Link className="link-font-size" to='/signup'>Sign Up</Link></li>
        </ul>
    </div>
</nav>

<ul id='mobile-sidenav-menu' className="sidenav">
    <li><Link to="#" className="sidenav-close right pink-text lighten-1">X</Link></li>  <li><Link className="link-font-size" to='/'>HOME</Link></li>
    <li><Link className="link-font-size" to='/about'>About</Link></li>
    <li><Link className="link-font-size" to='/contact'>Contact</Link></li>
    <li><Link className="link-font-size" to='/login'>Login</Link></li>
    <li><Link className="link-font-size" to='/signup'>Sign Up</Link></li>
</ul>

编辑：

Vanilla JS 初始化：

 document.addEventListener('DOMContentLoaded', function() {
    var elems = document.querySelectorAll('.sidenav');
    var instances = M.Sidenav.init(elems);
  });

重新项目设置

签出这篇文章。Matt 的组件设置如下：

 import React from 'react';

 import 'materialize-css/js/waves.js'
 import 'materialize-css/js/buttons.js'
 import 'materialize-css/js/carousel.js'
 import 'materialize-css/sass/materialize.scss'


class App extends React.component {

    componentDidMount() {

        const elems = window.document.querySelectorAll('.carousel');
        const options = {};
        window.M.Carousel.int(elems, options);
    }

    render(){...}

}

这可能会有所启发...？
