我使用脚本来旋转存储在无序列表中的各种图像。该脚本正在运行,但似乎删除了应用于特定 Li 的预设类。我希望脚本完全按照当前的方式工作,但不删除我在 Li 上设置的类。有人可以提供一些建议或修改吗?谢谢你。请参阅此处的示例小提琴:
http://jsfiddle.net/trobbins26/5U4Cr/5/
或以下脚本:
function theRotator() {
//Set the opacity of all images to 0
$('div.rotator ul li').css({opacity: 0.0});
//Get the first image and display it (gets set to full opacity)
$('div.rotator ul li:first').css({opacity: 1.0});
//Call the rotator function to run the slideshow, 6000 = change to next image after 6 seconds
setInterval('rotate()',4000);
}
function rotate() {
//Get the first image
var current = ($('div.rotator ul li.show')? $('div.rotator ul li.show') : $('div.rotator ul li:first'));
if ( current.length == 0 ) current = $('div.rotator ul li:first');
//Get next image, when it reaches the end, rotate it back to the first image
var next = ((current.next().length) ? ((current.next().hasClass('show')) ? $('div.rotator ul li:first') :current.next()) : $('div.rotator ul li:first'));
//Un-comment the 3 lines below to get the images in random order
//var sibs = current.siblings();
//var rndNum = Math.floor(Math.random() * sibs.length );
//var next = $( sibs[ rndNum ] );
//Set the fade in effect for the next image, the show class has higher z-index
next.css({opacity: 0.0})
.addClass('show')
.animate({opacity: 1.0}, 500);
//Hide the current image
current.animate({opacity: 0.0}, 1000)
.removeClass('show');
};
setTimeout(function(){
$(document).ready(function() {
//Load the slideshow
theRotator();
$('div.rotator').fadeIn(500);
$('div.rotator ul li').fadeIn(500); // tweek for IE
});
}, 500);
