how to display next bootstrap tab on button click
I want to display next bootstrap tabs one by one on button click.Right now on button click only the second tab is displayed as i have hard coded it what should be in place of the href="#second" how to get the particular id in the href?When I first click on other tabs instead of clicking on the first tab which is active then the user must get the error message that ' the user have to click the first tab and then the other tabs' using noty plugin means disable the other tabs except for the first tab on page load .
here is my code

Answer
By using $('.nav-tabs > .active').next('li').find('a') selector you can select next tab and make it active. And if next selector not found make the first tab active.
$(function(){
$('#changetabbutton').click(function(e){
e.preventDefault();
var next_tab = $('.nav-tabs > .active').next('li').find('a');
if(next_tab.length>0){
next_tab.trigger('click');
}else{
$('.nav-tabs li:eq(0) a').trigger('click');
}
});
