我想每隔3秒更换一次图片,但是在更改时我想要制作淡入淡出效果,我这样做了:

  <script type="text/javascript">
    var images = [];
    images[0] = "http://i2.ytimg.com/vi/Q1yo3mco40U/default.jpg";
    images[1] = "http://i2.ytimg.com/vi/ivmoCcYLrEk/default.jpg";
    images[2] = "http://i3.ytimg.com/vi/f7d8luQ6p2Q/default.jpg";
    images[3] = "http://i1.ytimg.com/vi/XzFmOKNf8sc/default.jpg";
    images[4] = "http://i2.ytimg.com/vi/-2m1e4g2MFM/default.jpg";
    images[5] = "http://i1.ytimg.com/vi/lK2TSYBh7fw/default.jpg";
    var loop;
    var i = 0;

    $(document).ready(function() {
        setTimeout(fadeDivs, 3000);   
    });

    function fadeDivs()
    {
        $('.product img').attr('src',images[i]).fadeOut(100);
        if (i < images.length - 1) {
            i++;                                
        } else {
            i = 0;                
        } 
    }
  </script>

<section id="product">
    <article class="product">
      <img src="http://i2.ytimg.com/vi/Q1yo3mco40U/default.jpg" />
    </article>
</section>

然而不起作用,我认为问题在于

$('.product img').attr('src',images[i]).fadeOut(100);

有更好的方法吗?

您需要使用fadeIn()fadeOut()以及完整的回调来执行此操作

var images = [];
images[0] = "http://i2.ytimg.com/vi/Q1yo3mco40U/default.jpg";
images[1] = "http://i2.ytimg.com/vi/ivmoCcYLrEk/default.jpg";
images[2] = "http://i3.ytimg.com/vi/f7d8luQ6p2Q/default.jpg";
images[3] = "http://i1.ytimg.com/vi/XzFmOKNf8sc/default.jpg";
images[4] = "http://i2.ytimg.com/vi/-2m1e4g2MFM/default.jpg";
images[5] = "http://i1.ytimg.com/vi/lK2TSYBh7fw/default.jpg";

var i = 0;
setInterval(fadeDivs, 3000);

function fadeDivs() {
    i = i < images.length ? i : 0;
    $('.product img').fadeOut(100, function(){
        $(this).attr('src', images[i]).fadeIn(100);
    })
    i++;
}
