javascript - 单击时关闭覆盖 Div

Question

我有两个按钮可以打开和关闭叠加层。

.trigger-overlay 用于显示菜单和 .overlay-close 用于多个覆盖以关闭它们。

.wrap 包装所有内容，并在通过添加 .wrap-open 类打开叠加层时立即滑动

这有效 .trigger-overlay 被点击但当 .overlay-close 被点击时。 See example . (单击第二张幻灯片中的链接 1 或链接 2)。

当点击 .overlay-close 时，我需要对下面的 JS 代码做什么才能删除 .wrap-open？

JavaScript

(function() {
  var triggerBttn = document.getElementsByClassName('trigger-overlay');
  var closeBttn = document.getElementsByClassName('overlay-close');
  var wrap = document.querySelector('div.wrap');
  transEndEventNames = {
      'WebkitTransition': 'webkitTransitionEnd',
      'MozTransition': 'transitionend',
      'OTransition': 'oTransitionEnd',
      'msTransition': 'MSTransitionEnd',
      'transition': 'transitionend'
    },
    transEndEventName = transEndEventNames[Modernizr.prefixed('transition')],
    support = {
      transitions: Modernizr.csstransitions
    };

  function toggleOverlay() {
    var overlay = document.getElementById(this.getAttribute('data-href'));

    // If overlay is open
    if (classie.has(overlay, 'zap')) {

      classie.remove(overlay, 'zap');
      classie.remove(wrap, 'wrap-open');
      classie.add(overlay, 'close');

      var onEndTransitionFn = function(ev) {
        if (support.transitions) {
          if (ev.propertyName !== 'visibility') return;
          this.removeEventListener(transEndEventName, onEndTransitionFn);
        }
        classie.remove(overlay, 'close');
      };

      if (support.transitions) {
        overlay.addEventListener(transEndEventName, onEndTransitionFn);
      } else {
        onEndTransitionFn();
      }
    }

    // If overlay isn't closed
    else if (!classie.has(overlay, 'close')) {
      classie.add(overlay, 'zap');
      classie.add(wrap, 'wrap-open');
    }
    // If overlay is closed
    else if (classie.has(overlay, 'close')) {
      classie.add(overlay, 'zap');
      classie.add(wrap, 'wrap-open');
    }
  }



  for (var i = 0; i < triggerBttn.length; i++) {
    triggerBttn[i].addEventListener('click', toggleOverlay);
  }

  //counts number of closeBttn and remove zap on click for all
  for (var i = 0; i < closeBttn.length; i++) {
    closeBttn[i].addEventListener('click', function() {
      this.parentNode.className = this.parentNode.className.replace(/(?:^|\s)zap(?!\S)/g, '');
    });
  }
})();

如您所见 - 基本上我只是告诉 #menu 位于 z-index: 180 .. 但我也消除了您对“classie”的使用，因为jquery 已经有了。尽管您知道使用纯 JS 方法来完成工作很好，但如果您已经在加载 jquery 为什么不利用它呢？ https://jsfiddle.net/te0s2e86/1/

#menu{ z-index: 180; }
