Question

我有这个jQuery滑块但是，现在我需要让它在开头自动开始滑动。目前只有点击向左或向右滑动才能实现。有人可以帮我怎么做吗？

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
  var currentPosition = 0;
  var slideWidth = 960;
  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">Кликни за лево</span>')
    .append('<span class="control" id="rightControl">Кликни за десно</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() }
  } 
});
</script>

这是我使用的html：

 <!-- Slideshow HTML -->
  <div id="slideshow">
    <div id="slidesContainer">
      <div class="slide">
        <img src="Images/banner/z1.png" alt="Добредојдовте во светот на децата!" />
      </div>
      <div class="slide">
        <img src="Images/banner/z2.png" />
      </div>
      <div class="slide">
        <img src="Images/banner/z3.png"/>
      </div>
    </div>
  </div>
  <!-- Slideshow HTML -->

将滑块放在单独的功能中：

var slideGo = function(elem){
    // Determine new position
    currentPosition = ($(elem).attr('id')=='rightControl') ? currentPosition+1 : currentPosition-1;

    // Hide / show controls
    manageControls(currentPosition);
    // Move slideInner using margin-left
    $('#slideInner').animate({
      'marginLeft' : slideWidth*(-currentPosition)
    });

然后从文档就绪处理程序调用该函数，传入对元素的引用：

$(document).ready(function(){
var elem = $('#myelement');
slideGo(elem);
});

将自动滚动添加到jquery滑块
