我想出了如何从其他帖子中在页面上放置2个滑块。 我唯一的最后一个问题是Prev＆amp;第二个滑块上的下一个箭头似乎不起作用。
我从最初构建第一个滑块的其他人那里获取了这个页面，并且根本不熟悉代码。多年来我一直在使用Wordpress。我去学习。
这是页面： GinaKetchum.com
index.html文件中的代码：
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/easySlider1.7.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#slider").easySlider({
auto: true,
continuous: true
});
$("#slider2").easySlider({
auto: true,
continuous: true
});
});
</script>
easySlider1.7.js中的代码：
(function($) {
$.fn.easySlider = function(options){
// default configuration properties

答案 0 :(得分：0)
更改第二个滑块的上一个/下一个按钮的ID，然后执行以下操作：
$("#slider2").easySlider({
auto: true,
continuous: true,
nextId: "slider1next",
prevId: "slider1prev"
});

这种改变似乎有效。
$(document).ready(function(){
$("#slider").easySlider({
auto: true,
continuous: true,
prevId: 'prevBtn',
nextId: 'nextBtn'
});
$("#slider2").easySlider({
auto: true,
continuous: true,
nextId: "slider1next",
prevId: "slider1prev"
});
});
