Heres the link so you can check it

http://queretaro.orsilin.com.mx/index.php?page=item/view/15/Probando

this is the part causing conflict

if (nextImageIndex === 0) {
            scrollapi.begin(200);
        } else if ( nextImageIndex % 4 === 0 && nextImageIndex > 0) {
            scrollapi.next(200);
        }

学习调试！

所以这意味着scrollapi未定义。看看它是在哪里定义的。

var scrollapi = $(".scrollable").data('scrollable');
console.log($(".scrollable").length);  // Says it is Zero...sooo hence your problem
console.log($(".scrollable").data('scrollable'));  //undefined

那么问题是什么？当此代码运行时，页面上没有具有 class 的元素.scrollable。
