自动播放的jQuery幻灯片

来看下效果图：

 

 

<script src="jquery.js" type="text/javascript"></script>
<script type="text/javascript">
var theInt = null;
var curclicked = 0;

$(function(){
	autoPlay();
})

function autoPlay(){
$('#transparence').css('opacity','0.4');
	$('#pic_list img').css({'opacity':'0.6'});
	$('#pic_list img:eq(0)').css({'top':'0','opacity':'1'});
	$('#pic_list a').click(function(){return false});
	t(0);
	$('#pic_list img').mouseover(function(){
		if($('#big_pic').attr('src') == $(this).attr('src')) return;
		t($('#pic_list img').index($(this)));
	});
}

  t = function(i){
	clearInterval(theInt);
	if( typeof i != 'undefined' )
    curclicked = i;
		$('#big_pic').fadeOut(0).fadeIn(500).attr('src',$('#pic_list img').eq(i).attr('src'));
		$('#big_imgs').attr('href',$('#pic_list img').eq(i).parents('a').attr('href'));
		$('#big_imgs').attr('title',$('#pic_list img').eq(i).parents('a').attr('title'));
		$('#pic_list img').eq(i).parents('li').nextAll('li').find('img').animate({top:15,opacity:0.6},500);
		$('#pic_list img').eq(i).parents('li').prevAll('li').find('img').animate({top:15,opacity:0.6},500);
		$('#pic_list img').eq(i).animate({top:0},500).css('opacity','1');
    theInt = setInterval(function (){
      i++;
      if (i > $('#pic_list img').length - 1) {i = 0};
      $('#big_pic').fadeOut(0).fadeIn(500).attr('src',$('#pic_list img').eq(i).attr('src'));
      $('#big_imgs').attr('href',$('#pic_list img').eq(i).parents('a').attr('href'));
      $('#big_imgs').attr('title',$('#pic_list img').eq(i).parents('a').attr('title'));
      $('#pic_list img').eq(i).parents('li').nextAll('li').find('img').animate({top:15,opacity:0.6},500);
      $('#pic_list img').eq(i).parents('li').prevAll('li').find('img').animate({top:15,opacity:0.6},500);
      $('#pic_list img').eq(i).animate({top:0},500).css('opacity','1');
    },3000)
}
</script>

写的不错。
不过要注意执行效率，把反复使用的jQuery对象用变量缓存起来，避免反复查找DOM。
