Bootstrap Tabs: Next & Previous Buttons for Forms

For bootstrap 4

<button class="btn btn-info btn-lg previous">Previous</button>
<button class="btn btn-info btn-lg next">Next</button>


$('.next').click(function () {
    $('.nav-tabs > .nav-item > .active').parent().next('li').find('a').trigger('click');
});

$('.previous').click(function () {
    $('.nav-tabs > .nav-item > .active').parent().prev('li').find('a').trigger('click');
});

First at All : ID MUST BE UNIQUE

Here is your working code : http://www.bootply.com/120472

HTML :

<ul class="nav nav-tabs">
    <li class="active"><a href="#tab1" data-toggle="tab">Shipping</a></li>
    <li><a href="#tab2" data-toggle="tab">Quantities</a></li>
    <li><a href="#tab3" data-toggle="tab">Summary</a></li>
</ul>
<div class="tab-content">
    <div class="tab-pane active" id="tab1">
        <a class="btn btn-primary btnNext" >Next</a>
    </div>
    <div class="tab-pane" id="tab2">
        <a class="btn btn-primary btnNext" >Next</a>
        <a class="btn btn-primary btnPrevious" >Previous</a>
    </div>
    <div class="tab-pane" id="tab3">
        <a class="btn btn-primary btnPrevious" >Previous</a>
    </div>
</div>

JS :

 $('.btnNext').click(function(){
  $('.nav-tabs > .active').next('li').find('a').trigger('click');
});

  $('.btnPrevious').click(function(){
  $('.nav-tabs > .active').prev('li').find('a').trigger('click');
});

Snippet:

 $('.btnNext').click(function(){
  $('.nav-tabs > .active').next('li').find('a').trigger('click');
});

  $('.btnPrevious').click(function(){
  $('.nav-tabs > .active').prev('li').find('a').trigger('click');
});

Anyone who want to perform next previous operations on tab, follow following steps:

a) Put next prev buttons in each tab-panel

b) Bind the buttons clicks to body so that it will be called on click

c) On click trigger click of next/prev tab

d) If it is last tab redirect user to appropriate tab (Call show events of first or last tab)

/**** JQuery *******/
jQuery('body').on('click','.next-tab', function(){
      var next = jQuery('.nav-tabs > .active').next('li');
      if(next.length){
        next.find('a').trigger('click');
      }else{
        jQuery('#myTabs a:first').tab('show');
      }
});

jQuery('body').on('click','.previous-tab', function(){
      var prev = jQuery('.nav-tabs > .active').prev('li')
      if(prev.length){
        prev.find('a').trigger('click');
      }else{
        jQuery('#myTabs a:last').tab('show');
      }
});
