这种紧急情况，求各位大神帮帮我……
我正在为幻灯片使用movingboxes插件（这是原始插件：http://css-tricks.com/moving-boxes/）我需要帮助设置回调函数添加到动画的末尾。我需要添加淡入淡出效果，当currentSlidecomplete滑动时，它应该开始淡入同一图像的另一个视图，例如，surrentSlidesrc 是images/dr1.jpg，我需要它淡入images/dr1b.jpg并返回到 images/dr1.jpg。循环遍历每个当前幻灯片
类似完成的东西：
function(e, slider, tar){
//fading for each currentSlide goes here;//
}
像你描述的东西已经在文档中
请参阅此处的文档 [1]，更具体地说，请参阅此处的文档 [2]。
编辑：在这里检查 jsfiddle，我使用了一个 jquery 插件http://jsfiddle.net/r6yWC/157/ 插件在这里http://jqueryfordesigners.com/image-cross-fade-transition/ 我还编辑了下面的代码部分。我在 img 标签中添加了“fade”类，如下所示：
<img class="fade" src="http://chriscoyier.github.com/MovingBoxes/demo/4.jpg" alt="picture" style="background: url(http://chriscoyier.github.com/MovingBoxes/demo/2.jpg);"/>
在第二个链接中，您将找到一个带有已完成回调的movingBoxes 示例。
(function ($) {
$.fn.cross = function (options) {
return this.each(function (i) {
// cache the copy of jQuery(this) - the start image
var $$ = $(this);
// get the target from the backgroundImage + regexp
var target = $$.css('backgroundImage').replace(/^url|[\(\)'"]/g, '');
// nice long chain: wrap img element in span
$$.wrap('<span style="position: relative;"></span>')
// change selector to parent - i.e. newly created span
.parent()
// prepend a new image inside the span
.prepend('<img>')
// change the selector to the newly created image
.find(':first-child')
// set the image to the target
.attr('src', target);
// the CSS styling of the start image needs to be handled
// differently for different browsers
if ($.browser.msie || $.browser.mozilla) {
$$.css({
'position' : 'absolute',
'left' : 0,
'background' : '',
'top' : this.offsetTop
});
} else if ($.browser.opera && $.browser.version < 9.5) {
// Browser sniffing is bad - however opera < 9.5 has a render bug
// so this is required to get around it we can't apply the 'top' : 0
// separately because Mozilla strips the style set originally somehow...
$$.css({
'position' : 'absolute',
'left' : 0,
'background' : '',
'top' : "0"
});
} else { // Safari
$$.css({
'position' : 'absolute',
'left' : 0,
'background' : ''
});
}
// similar effect as single image technique, except using .animate
// which will handle the fading up from the right opacity for us
$$.hover(function () {
$$.stop().animate({
opacity: 0
}, 250);
}, function () {
$$.stop().animate({
opacity: 1
}, 250);
});
});
};
})(jQuery);
$('#slider').movingBoxes({
// **** Appearance ****
// start with this panel
...
...
//-----> here is your callback
// callback after animation completes
completed: function(e, slider, tar){
var img = slider.$panels.eq(tar).find('img');
img.cross();
img.stop().animate({opacity: 0}, 1250).delay(500).animate({opacity: 1}, 2550);
