sensitiveslides.js-获取当前幻灯片 [英] responsiveslides.js - get current slide
问题描述
需要从当前处于活动状态的幻灯片中获取数据编号"值.我想使用此值在页面的另一个div中显示/隐藏其他信息.或者,如果除了添加特定的数据编号"值之外,还有其他方法让我知道-我在文档中看不到任何返回幻灯片编号的
Need to get the 'data-number' value from the current slide that is active in the slider. I want to use this value to show/hide additional info in another div of the page. Or if there is some other way other than adding a specific 'data-number' values let me know - I saw nothing in the doc which returning the slide number.
我知道我可以使用之后"回调执行我想要的操作,但不确定如何首先获得该值.
I know I can use the 'after' callback to then do what I want, but not sure how I can go about getting this value in the first place.

推荐答案
无需在列表中添加数据属性.您可以像这样获取当前幻灯片的索引:
No need to add a data attribute to the list. You can take the index of the current slide like this:
$("#slider1").responsiveSlides({
after: function(i){
// i is equal to the index of the current active slide
// Your code here
}
);
