How to get current step?

[mahony0]

I'm not really good at JS. I want to check current step number. Tried this:

$("body").on('click', ".btn-next", function() {
    var activeTabNo = $("li.active").data("step");
    alert(activeTabNo);
});

but no luck.

Also a small demonstration for how to change the step programmatically will be very helpful
