我对Bootstrap Native中的手风琴有疑问。除了一件事，一切都很好。在扩展其他 .collapsed 手风琴后，该类不会添加到已开发的前者中。我已经尝试了几种方法，但仍然没有。添加collapsed类是addClass（元素，折叠）；只是另一种方式 removeClass ... 在 JS 文件下面：

// event targets and constants
var accordion = null, collapse = null, self = this, 
  isAnimating = false, // when true it will prevent click handlers
  accordionData = element[getAttribute]('data-parent'),

  // component strings
  component = 'collapse',
  collapsed = 'collapsed',
  test = 'test'

  // private methods
  openAction = function(collapseElement) {
    bootstrapCustomEvent.call(collapseElement, showEvent, component);
    isAnimating = true;
    addClass(collapseElement,collapsing);
    addClass(collapseElement,showClass);
    addClass(element,collapsed);

    setTimeout(function() {
      collapseElement[style][height] = getMaxHeight(collapseElement) + 'px';


      (function(){
        emulateTransitionEnd(collapseElement, function(){
          isAnimating = false;
          collapseElement[setAttribute](ariaExpanded,'true');
          removeClass(collapseElement,collapsing);
          collapseElement[style][height] = '';
          bootstrapCustomEvent.call(collapseElement, shownEvent, component);
        });
      }());
    }, 20);
  },
  closeAction = function(collapseElement) {
    bootstrapCustomEvent.call(collapseElement, hideEvent, component);
    isAnimating = true;
    collapseElement[style][height] = getMaxHeight(collapseElement) + 'px';
    setTimeout(function() {
      addClass(collapseElement,collapsing);

      collapseElement[style][height] = '0px';
      (function() {
        emulateTransitionEnd(collapseElement, function(){

          isAnimating = false;
          collapseElement[setAttribute](ariaExpanded,'false');
          removeClass(collapseElement,collapsing);
          removeClass(collapseElement,showClass);
          collapseElement[style][height] = '';
          bootstrapCustomEvent.call(collapseElement, hiddenEvent, component);
        });
      }());
    },20);
  },
  getTarget = function() {
    var href = element.href && element[getAttribute]('href'),
      parent = element[getAttribute](dataTarget),
      id = href || ( parent && targetsReg.test(parent) ) && parent;
    return id && queryElement(id);
  };

// public methods
this.toggle = function(e) {
  e.preventDefault();
  if (isAnimating) return;
  if (!hasClass(collapse,showClass)) { 
      self.show(); 
  } else { 
      self.hide(); 
  }
};
this.hide = function() {
  closeAction(collapse);
  addClass(element,collapsed);
//jak się zwija dodaje klase
};
this.show = function() {
  openAction(collapse);
  removeClass(element,collapsed);
//jak się rozwija usuwa klase

  if ( accordion !== null ) {
    var activeCollapses = getElementsByClassName(accordion,component+' '+showClass);

    for (var i=0, al=activeCollapses[length]; i<al; i++) {
      if ( activeCollapses[i] !== collapse) closeAction(activeCollapses[i]);
    }
  }
};

// init
if ( !(stringCollapse in element ) ) { // prevent adding event handlers twice
  on(element, clickEvent, this.toggle);
}
collapse = getTarget();
accordion = queryElement(options.parent) || accordionData && getClosest(element, accordionData);
element[stringCollapse] = this;
};

如您所见，代码并未添加到先前开发的( <a href...).collapsed手风琴中。
