我在我的网站中使用优惠滑块，其中包含 16 张幻灯片。我想保持导航（上一个和下一个按钮）到滑块，我可以使用这些按钮移动到每张幻灯片。（目前有导航按钮从一个页面移动到另一个我不想要的页面）

这可能吗？

OFFFFFFFFFFFFO atlast 我找到了自己的解决方案....请检查下面的更新代码以获取解决方案。我唯一改变的是上一个和下一个按钮代码。

希望对其他人有所帮助。

js

var os_desc = '.desc';      // slide description element selector

var os_pagerElementsOnPage = 1;     // number of pager elements on page
var os_pagerElementWidth = 160;
var os_pagerWidth = os_pagerElementsOnPage * os_pagerElementWidth;

var os_manual = false;      // true - pause, false - play
var os_currPage = 0;        // current page number ( 0 - start )
