如何在 reactjs 中 jquery / js？

Question

我想在我的 reactjs 代码中复制 this codpepen example。我可以使用 css 获得准确的页面样式，但是单击按钮时不会发生屏幕对齐，这是 jscript/jquery 的工作。由于我是reactjs的新手，请帮助我。

我的代码在 codepen 中作为参考 here

$('.nav-toggle').click(function(e) {
  
  e.preventDefault();
  $("html").toggleClass("openNav");
  $(".nav-toggle").toggleClass("active");

});

body {
  font-family: 'Work Sans', sans-serif;
  margin: 0;
  background-color: #eee;
}

/* Layout */

#container {
  padding: 0;
  margin: 0;
  background-color: #fff;
}

#main {
  padding: 4% 1.5em;
  max-width: 55em;
  margin: 0 auto;
}

#header {
  padding: 1.5em;
  margin: 0 0 1em 0;
  background-color: #eee;
}

#footer {
  padding: 1.5em;
  margin: 2em 0 0 0;
  background-color: #eee;

}

                and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

您真的不应该在项目中包含 jQuery 只是为了向元素添加点击事件侦听器。但如果需要的话：
