bootstrap.js手风琴有效索引？

Question

I am attempting to retrieve the active index so that I can use previous / next buttons, and also error check the form values in each stage of the accordion.

Is there a way to get the active index of the accordion?

Answer 1

var index = $('#accordion .in').parent().index();

Answer 2

You can get the accordion-group that is a accordion item, using that:

var accordionItem = $('.accordion .accordion-body.in:first').parents('.accordion-group');

Now you can get the index of accordionItem.
