所有。我正在为我正在进行的项目构建一个全屏jQuery画廊,并且正在进行一次小打击。
要查看正在发生的事情的演示,请访问http://www.idealbrandon.com/gallery.html。
基本上,我使用自定义属性data-background为每张幻灯片加载bg-image。这在第一次工作正常,但是无论何时第二次加载幻灯片,它都不会加载。幻灯片的HTML是:
<div class="slide" data-background="/img/gallery/2.jpg">
<div class="location">Magical Aqua Ducks</div>
<div class="verse"></div>
</div>
有问题的Javascript是
for(var i = 0; i < totalSlides; i++){
$pagerList
.append('<li class="page" data-target="'+i+'"></li>');
if ($slides.eq(i).attr("data-background") != null){
$slides.eq(i).css("background-image", "url("+$slides.eq(i).attr("data-background")+")");
};
};
并且整个javascript文件是
(function($){
function prefix(el){
var prefixes = ["Webkit", "Moz", "O", "ms"];
for (var i = 0; i < prefixes.length; i++){
if (prefixes[i] + "Transition" in el.style){
return '-'+prefixes[i].toLowerCase()+'-';
};
};
return "transition" in el.style ? "" : false;
};
var methods = {
init: function(settings){
return this.each(function(){
var config = {
slideDur: 7000,
fadeDur: 800
};
if(settings){
$.extend(config, settings);
};
this.config = config;
var $container = $(this),
slideSelector = '.slide',
fading = false,
slideTimer,
activeSlide,
newSlide,
$slides = $container.find(slideSelector),
totalSlides = $slides.length,
$pagerList = $container.find('.pager_list');
prefix = prefix($container[0]);
function animateSlides(activeNdx, newNdx){
function cleanUp(){
$slides.eq(activeNdx).removeAttr('style');
activeSlide = newNdx;
fading = false;
waitForNext();
};
if(fading || activeNdx == newNdx){
return false;
};
fading = true;
$pagers.removeClass('active').eq(newSlide).addClass('active');
$slides.eq(activeNdx).css('z-index', 3);
$slides.eq(newNdx).css({
'z-index': 2,
'opacity': 1
});
if(!prefix){
$slides.eq(activeNdx).animate({'opacity': 0}, config.fadeDur,
function(){
cleanUp();
});
} else {
var styles = {};
styles[prefix+'transition'] = 'opacity '+config.fadeDur+'ms';
styles['opacity'] = 0;
$slides.eq(activeNdx).css(styles);
//$slides.eq(activeNdx).css("background-image", "url("+$slides.eq(activeNdx).attr("data-background")+")");
var fadeTimer = setTimeout(function(){
cleanUp();
},config.fadeDur);
};
};
function changeSlides(target){
if(target == 'next'){
newSlide = (activeSlide * 1) + 1;
if(newSlide > totalSlides - 1){
newSlide = 0;
}
} else if(target == 'prev'){
newSlide = activeSlide - 1;
if(newSlide < 0){
newSlide = totalSlides - 1;
};
} else {
newSlide = target;
};
animateSlides(activeSlide, newSlide);
};
function waitForNext(){
slideTimer = setTimeout(function(){
changeSlides('next');
},config.slideDur);
};
for(var i = 0; i < totalSlides; i++){
$pagerList
.append('<li class="page" data-target="'+i+'"></li>');
if ($slides.eq(i).attr("data-background") != null){
$slides.eq(i).css("background-image", "url("+$slides.eq(i).attr("data-background")+")");
//alert($slides.eq(i).attr("data-background"));
};
};
$container.find('.page').bind('click',function(){
var target = $(this).attr('data-target');
clearTimeout(slideTimer);
changeSlides(target);
});
var $pagers = $pagerList.find('.page');
$slides.eq(0).css('opacity', 1);
$pagers.eq(0).addClass('active');
activeSlide = 0;
waitForNext();
});
}
};
$.fn.easyFader = function(settings){
return methods.init.apply(this, arguments);
};
})(jQuery);

看了一下你的gallery.js文件,你就有了以下淡入过渡调用的函数:cleanUp()
在此功能中,您可以从$slides
:
$slides.eq(activeNdx).removeAttr('style');
这也是删除背景图片样式。然后再从未设置过。
在您删除样式的上一行之后,您可能需要包括:
$slides.eq(activeNdx).css("background-image", "url("+$slides.eq(activeNdx).data("background")+")");
