Javascript，在打开和关闭按钮之间切换以推送内容div

Question

背景：

• 开放模式/叠加全屏
• 已禁用父级滚动
• 并启用了叠加滚动功能
单击open按钮时
• 内容推送

哪个效果很好。

但是当单击close按钮时，我无法获得相反的效果：它正在关闭而没有效果。

如果有人可以帮我这个。对此，我真的非常感激。非常感谢你。

var body = document.body,
  overlay = document.querySelector('.modalbox'),
  overlayBtts = document.querySelectorAll('button[class$="modalbox"]');

[].forEach.call(overlayBtts, function(btt) {

  btt.addEventListener('click', function() {

    /* Detect the button class name */
    var overlayOpen = this.className === 'open-modalbox',
      overlayClose = this.className === 'close-modalbox';
    /* Toggle the aria-hidden state on the overlay and the 
       no-scroll class on the body */
    overlay.setAttribute('aria-hidden', !overlayOpen);
    overlay.classList.toggle('modalbox-active', overlayOpen);
    overlay.classList.toggle('modalbox-active-reverse', overlayClose);
    body.classList.toggle('noscroll', overlayOpen);


    /* On some mobile browser when the overlay was previously
       opened and scrolled, if you open it again it doesn't 
       reset its scrollTop property */
    overlay.scrollTop = 0;

  }, false);

$(document).ready(function () {
  $(".modalbox").hide();
  $("#trigger").on("click", function(){
    $(".modalbox").show();
  });
});
var body = document.body,
  overlay = document.querySelector('.modalbox'),
  overlayBtts = document.querySelectorAll('button[class$="modalbox"]');

[].forEach.call(overlayBtts, function(btt) {

  btt.addEventListener('click', function() {

    /* Detect the button class name */
    var overlayOpen = this.className === 'open-modalbox',
      overlayClose = this.className === 'close-modalbox';
    /* Toggle the aria-hidden state on the overlay and the 
       no-scroll class on the body */
    overlay.setAttribute('aria-hidden', !overlayOpen);
    overlay.classList.toggle('modalbox-active', overlayOpen);
    overlay.classList.toggle('modalbox-active-reverse', overlayClose);
    body.classList.toggle('noscroll', overlayOpen);


    /* On some mobile browser when the overlay was previously
       opened and scrolled, if you open it again it doesn't 
       reset its scrollTop property */
    overlay.scrollTop = 0;

  }, false);
});

.noscroll {
  overflow: hidden;
}

.modalbox {
  position: fixed;
  overflow-y: scroll;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  height: 100%;
  background-color: orange;
  z-index: 50;
}

.modalbox-active {
  animation: ease slideright .4s 1 forwards;
}

@keyframes slideright {
  0% {
    width: 0;
  }
  100% {
    width: 100%;
  }
}

.modalbox-active-reverse {
  width: 0;
  animation: ease slideleft .4s 1;
}

@keyframes slideleft {
  0% {
    width: 100%;
  }
  100% {
    width: 0;
  }
}

使用JQUERY在加载时隐藏模态，当用户单击按钮时打开窗口。还需要删除下面的CSS代码。

[aria-hidden="true"] {
  display: none;
}

[aria-hidden="false"] {
  display: block;
}
