Jquery内容滑块边距问题

Question

我遇到了jquery内容滑块的问题，特别是这个http://sixrevisions.com/tutorials/javascript_tutorial/create-a-slick-and-accessible-slideshow-using-jquery/。

滑块提供了一个更大的margin-left值，该值是slideInner div所需的。 slideInner div往往有额外的300到500个额外的px边距，这留下了空间。我宁愿没有额外的保证金，我该如何解决这个问题呢？

干杯可可，

 var currentPosition = 0; 
 var slideWidth = 960;
 var slides = $('.column'); var    
 numberOfSlides = slides.length;

  // Remove scrollbar in JS
  $('.content').css('overflow', 'hidden');

  // Wrap all .slides with #slideInner div
  slides
  .wrapAll('<div id="slideInner"></div>')
  // Float left to display horizontally, readjust .slides width
  .css({
    'width' : slideWidth
  });

// Set #slideInner width equal to total width of all slides
$('.content').css('width', slideWidth * numberOfSlides);


// Insert controls in the DOM
$('.nav_arrow')
.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){
// Hide left arrow if position is first slide
if(position==0){ $('#leftControl').hide() } else{ $('#leftControl').show() }
// Hide right arrow if position is last slide
if(position==numberOfSlides-1){ $('#rightControl').hide() } else{   $('#rightControl').show() }
}   
});
