我已经坚持了几天这个问题了,这真让我很沮丧。我正在编写我认为应该是div中的简单无限图像交换,然后将该特定div称为一个类,以便我可以在同一页面上多次使用它。这是我在下面使用的代码:
HTML:
<div class="project">
<div class="project_images">
<img src="../images/portfolio/placeholder.jpg" />
<img src="../images/portfolio/placeholder2.jpg" />
<img src="../images/portfolio/placeholder3.jpg" />
<img src="../images/portfolio/placeholder4.jpg" />
</div>
<div class="project_buttons">
<a href="#" class="prev">PREV</a>
<a href="#" class="next">NEXT</a>
</div>
</div>
<div class="project">
<div class="project_images">
<img src="../images/portfolio/placeholder.jpg" />
<img src="../images/portfolio/placeholder2.jpg" />
<img src="../images/portfolio/placeholder3.jpg" />
<img src="../images/portfolio/placeholder4.jpg" />
</div>
<div class="project_buttons">
<a href="#" class="prev">PREV</a>
<a href="#" class="next">NEXT</a>
</div>
</div>
和jQuery:
$(document).ready(function(){
next = function(){
var thisFirst = $(this).parents('div').prev('.project_images img:first');
var thisLast = $(this).parents('div').prev('.project_images img:last');
thisLast.after(thisFirst);
}
prev = function(){
var thisFirst = $(this).parent('div').prev('.project_images img:first');
var thisLast = $(this).parent('div').prev('.project_images img:last');
thisFirst.before(thisLast);
}
$('.prev').click(function(){
prev();
});
$('.next').click(function(){
next();
});
});
单击第一个div类中的“NEXT”按钮时,图像将放入同名的第二个div类(“project_images”)。我理解它为什么这样做(:first
和:last
选择器),但我无法找到更好的方法来选择对象和/或只选择一个“project_images”类的实例。
任何帮助将不胜感激......

$(document).ready(function(){
next = function(){
var thisFirst = $(this).parents('.project').find('.project_images img:first');
var thisLast = $(this).parents('.project').find('.project_images img:last');
thisLast.after(thisFirst);
}
prev = function(){
var thisFirst = $(this).parents('.project').find('.project_images img:first');
var thisLast = $(this).parents('.project').find('.project_images img:last');
thisFirst.before(thisLast);
}
$('.prev').click(prev);
$('.next').click(next);
});
