如何防止Photowipe取消绑定滚动事件？

Question

[ situation ] I have problems about photoswipe close. I have a html page A using Photoswipe for a photo view. I have defined a scroll event in page A. When I open and then close photoswipe and go back to my page A, the scroll event is not working any more.

My scroll event:

$(window).scroll(function(){
  if ((getDocumentHeight() - getWindowHeight() - getSrollHeight()) == 0) {
    alert("buttom");
  };
});

I noticed photoswipe's close and destory method call _unbindEvents methods, which executes the unbind function.

// Closes the gallery, then destroy it
close: function() {
    if(!_isOpen) {
        return;
    }

    _isOpen = false;
    _isDestroying = true;
    _shout('close');
    _unbindEvents();

    _showOrHide( self.currItem, null, true, self.destroy);
},
// destroys gallery (unbinds events, cleans up intervals and timeouts to avoid memory leaks)
destroy: function() {
    _shout('destroy');

    if(_showOrHideTimeout) {
        clearTimeout(_showOrHideTimeout);
    }

    template.setAttribute('aria-hidden', 'true');
    template.className = _initalClassName;

    if(_updateSizeInterval) {
        clearInterval(_updateSizeInterval);
    }

    framework.unbind(self.scrollWrap, _downEvents, self);

    // we unbind lost event at the end, as closing animation may depend on it
    framework.unbind(window, 'scroll', self);

    _stopDragUpdateLoop();

    _stopAllAnimations();

    _listeners = null;
},
_unbindEvents = function() {
    framework.unbind(window, 'resize', self);
    framework.unbind(window, 'scroll', _globalEventHandlers.scroll);
    framework.unbind(document, 'keydown', self);
    framework.unbind(document, 'mousemove', _onFirstMouseMove);

    if(_features.transform) {
        framework.unbind(self.scrollWrap, 'click', self);
    }

    if(_isDragging) {
        framework.unbind(window, _upMoveEvents, self);
    }

    _shout('unbindEvents');
},

[ question ] How can I prevent photoswipe to unbind my scroll event?

Answer 1

Never used photoswipe, but according to the comment

// we unbind lost event at the end, as closing animation 'may' depend on it

what happens if you remove the line?

framework.unbind(window, 'scroll', self);

Answer 2

I have fixed this problem.

$(document).scroll() 

instead of

$(window).scroll() 

It's working.
