jQuery循环插件，嵌套幻灯片，“之后"选项或测试第一张和最后一张图片 [英] jquery cycle plugin, nested slideshow, 'after' option or testing for first and last image
问题描述
在嵌套的幻灯片中，我具有上一个"和下一个"控件.如果您在第一张幻灯片上，我希望能够降低css的不透明性，如果在最后一张幻灯片上，则可以降低下一页"的css不透明度.
In my nested slideshows I have 'prev' and 'next' controls. I would like to be able to reduce the css opacity of 'prev' if you are on the first slide and 'next' if you are on the last slide.
'after:onAfter'选项就足够了，但是当放置在我的嵌套幻灯片显示控件的代码中时，它似乎不起作用.
The 'after: onAfter' option would have been sufficient but it didn't appear to work when placed in my code for the nested slideshow controls.
是否有办法在嵌套幻灯片中正确实现之后"，或者测试嵌套幻灯片中的第一张和最后一张图像?谢谢
Is there a way to implement 'after' correctly in a nested slideshow, or alternatively test for first and last images in the nested slideshow? Thankyou
这是我的代码.

推荐答案
我认为这就是您想要的(编辑您的示例): http://jsfiddle.net/m8AFG/18/
I think this is what you wanted (edited your example): http://jsfiddle.net/m8AFG/18/
$(document).ready(function() {
// init and stop the inner slideshows
var inners = $('.inner-slideshow').cycle().cycle('stop');
var slideshow = $('#slideshow').cycle({
fx: 'fade',
speed: 'fast',
timeout: 0,
pager: '#nav',
pagerAnchorBuilder: function(idx, slide) {
// return sel string for existing anchor
return '#nav li:eq(' + (idx) + ') a';
},
before: function() {
// stop all inner slideshows
inners.cycle('stop');
// start the new slide's slideshow
$(this).cycle({
fx: 'scrollHorz',
speed: 'fast',
timeout: 0,
prev: '#prev',
next: '#next',
nowrap: 1,
after: function() {
$('#prev').removeClass('opac');
$('#next').removeClass('opac');
var countImg = $(this).siblings().size();
if ($(this).index() == 0) $('#prev').addClass('opac');
if ($(this).index() == countImg) $('#next').addClass('opac');
}
});
}
});
});
添加了CSS的不透明度以及jquery和cycle脚本链接，并且效果很好
added css opacity and the jquery and cycle script link, and it works fine
