Answer 1

This one is quite straightforward from w3schools: https://www.w3schools.com/bootstrap/bootstrap_ref_js_tab.asp

// Select tab by name
$('.nav-tabs a[href="#home"]').tab('show')

// Select first tab
$('.nav-tabs a:first').tab('show') 

// Select last tab
$('.nav-tabs a:last').tab('show') 

// Select fourth tab (zero-based)
$('.nav-tabs li:eq(3) a').tab('show')
