取消鼠标悬停时的Jquery滑动条事件

我编写了以下代码来尝试取消鼠标悬停时的事件。目标是在幻灯片当前处于悬停状态时防止发生滑动事件。如果当前幻灯片处于悬停状态，是否可以取消幻灯片事件?下面是我的代码:

<script type="text/javascript">
$(document).ready(function(){
  var currentPosition = 0;
  var slideWidth = 560;
  var slides = $('.slide');
  var numberOfSlides = slides.length;
  // Remove scrollbar in JS
  $('#slidesContainer').css('overflow', 'hidden');
  // Wrap all .slides with #slideInner div
  slides
    .wrapAll('<div id="slideInner"></div>')
    // Float left to display horizontally, readjust .slides width
    .css({
      'float' : 'left',
      'width' : slideWidth
    });
  // Set #slideInner width equal to total width of all slides
  $('#slideInner').css('width', slideWidth * numberOfSlides);
  // Insert controls in the DOM
  $('#slideshow')
    .prepend('<span class="control" id="leftControl">Clicking moves left</span>')
    .append('<span class="control" id="rightControl">Clicking moves right</span>');
  // Hide left arrow control on first load
  manageControls(currentPosition);
  // Create event listeners for .controls clicks
  $('.control')
    .bind('click', function(){
    // Determine new position
    currentPosition = ($(this).attr('id')=='rightControl') ? currentPosition+1 : currentPosition-1;
    // Hide / show controls
    manageControls(currentPosition);
    // Move slideInner using margin-left
    $('#slideInner').animate({
      'marginLeft' : slideWidth*(-currentPosition)
    });
  });

     // manageControls: Hides and Shows controls depending on currentPosition
      function manageControls(position){
                if(position >= 4)
                {
                    position=0;
                    currentPosition=0;
                }
      } 
      function Aplay(){
        // Determine new position
        currentPosition =  currentPosition+1 ;
        // Hide / show controls
        manageControls(currentPosition);
        // Move slideInner using margin-left
        $('#slideInner').animate({
          'marginLeft' : slideWidth*(-currentPosition)
        });
          setTimeout(function(){Aplay();},5000);
      }
      setTimeout(Aplay(),50000);
});
</script>
