Bootstrap：下一个按钮应显示下一个选项卡

Question

I want to implement a custom next button into the bootstrap tab navigation.

When clicking on the next-button, the next tab should be displayed as active. If the last tab is reached it should start with the first tab.

This solve your problem

$('.next-tab').click(function(e){
  if($('.nav-tabs > .active').next('li').hasClass('next-tab')){
    $('.nav-tabs > li').first('li').find('a').trigger('click');
  }else{
    $('.nav-tabs > .active').next('li').find('a').trigger('click');
  }
  e.preventDefault();
});

I Recently needed this functionality and this is what I ended up with:

 $('.change-tab').click(function() { var $this = $(this); var $nav = $($this.data('target')) var $tabs = $nav.find('li'); var $curTab = $tabs.filter('.active'); var cur = $tabs.index($curTab); if ($this.data('direction') == 'next') var $showTab = cur == $tabs.length - 1 ? $tabs.eq(0).find('a') : $tabs.eq(cur + 1).find('a'); else var $showTab = cur == 0 ? $tabs.eq($tabs.length - 1).find('a') : $tabs.eq(cur - 1).find('a'); $showTab.tab('show'); }); // normal tabs code $('#myTab a').click(function (e) { e.preventDefault(); $(this).tab('show'); }); $(function () { $('#myTab a:last').tab('show'); })

I am using @DelightedD0D provided solution. When the page load, the control stop on the last tab always. If you want to fix this, please update the following function

$(function () {
$('#myTab a:last').tab('show');
})

to

$(function () {
$('#myTab a:active').tab('show');
})
