tabs need to click twice to change the tab to the active tab
Question
I had a problem about the active tab.I use .append() to built tabs and I don't use href to connect data of tab.
when I click tab .console log() to show the text of the active tab.
My problem is when I clicked tab 2 the text of the active tab still is tab 1.
I have to clicked tab 2 again the active tab gonna change to tab 2. I don't see anyone who has the same problem so wish someone can help me. Thanks.

Use shown.bs.tab event instead of click .
$(".nav-tabs a").on('shown.bs.tab', function () {
alert('set_active = ' + $('.nav-tabs .active').text());
});

You just need to apply 'addClass' method at the time of click event,that you can see in below snippet :
$(document).ready(function(){ for(i = 1;i <= 2 ; i++){ renewid='tab_'+i; if(i == 1){ $('.nav-tabs').append("<li><a data-toggle='tab' id=" + renewid + ">Chart"+ [i] +"</a></li>"); } else{ $('.nav-tabs').append("<li><a data-toggle='tab' id=" + renewid + ">Chart"+ [i] +"</a></li>"); } }; $(".nav-tabs a").click(function(){ $('.nav-tabs').find('li').removeClass('active'); $(this).closest('li').addClass('active') alert('set_active = ' + $('.nav-tabs .active').text()); }); });
