Answer 3

The question does not mention that jquery is preferred or required, although it has a jQuery tag. In vanilla javascript, you can achieve this with:

 var value; var active = document.querySelector('.rb-tab-active'); if (active) { var value = active.getAttribute('data-value'); console.log(value); } 

Answer 4

Select the div and use Jquery data() function or attr().

$(".rb-tab-active").data("value");

or

$(".rb-tab-active").attr("value");

Refer these..

https://api.jquery.com/jquery.data/

http://api.jquery.com/attr/

If no jquery using

document.getElementsByClassName("rb-tab-active").getAttribute("data-value");
