Button to Trigger Nav-Tab with Twitter Bootstrap

Question

This button triggers the next tab to load content, but the tab itself does not switch, it remains on the first tab..

Answer 1

It's quite simple with Bootstrap 4 & JQuery, i'm using this solution:

 $(document).ready(function(){
        activaTab('aaa');
    });

    function activaTab(tab){
        $('.tab-pane a[href="#' + tab + '"]').tab('show');
    };
