我想出了如何在其他帖子的页面上有 2 个滑块。我唯一的最后一个问题是第二个滑块上的 Prev & Next 箭头似乎不起作用。
我从最初构建第一个滑块并且根本不熟悉代码的其他人那里接管了这个页面。多年来，我一直主要使用 Wordpress。边走边学。
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
