将类collapse in类更改为collapse show，这就是代码变得不兼容的原因.

Classes collapse in classes were changed into collapse show, that's why the code became incompatible.

getTemplate:

getTemplate:

if (hasDate()) {
 content.append($('<li>').addClass((options.collapse && hasTime() ? 'collapse in' : '')).append(dateView));

更改为:

if (hasDate()) {
  content.append($('<li>').addClass((options.collapse && hasTime() ? 'collapse show' : '')).append(dateView));
  }

togglePicker:

togglePicker:

   expanded = $parent.find('.in'),
  closed = $parent.find('.collapse:not(.in)'),

和

   } else { // otherwise just toggle in class on the two views
     expanded.removeClass('in');
     closed.addClass('in');

更改为:

 expanded = $parent.find('.show'),
 closed = $parent.find('.collapse:not(.show)'),

和

  } else { // otherwise just toggle in class on the two views
  expanded.removeClass('show');
 closed.addClass('show');
