Bootstrap shown.bs.tab event not working

Question

I\'m using the Flexy template (using bootstrap) and I can\'t get the shown.bs.tab event on tab to work.

I\'ve managed to make it work on JSFiddle.

Here is the co

Answer 1

The issue I faces was that I had 2 sets of tabs on my page. and I had already bound the 1st tab set with

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
  console.log(e.target.href);
})

For the 2nd tab set also i had defined the same way.. but I had assigned an id to the ul and bound the click element as:

  $('#tabId > li > a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
      console.log(e.target.href);
    })

The 1st tab was working here but the 2nd wouldn't work. I then figured it out and assigned id's to both uls.. now it works

Answer 2

The issue was more a rails-related one.

I ended up by removing one by one every piece of code since the issue was not there in the raw template as @KyleMit says.

Whenever I remove the line //= require bootstrap-sprockets from my application.js file the issue disappears !

The issue was that I was requiring both bootstrap and bootstrap-sprockets. I should have require just one of them but not both.

Bootstrap tab events are based off the .nav-tabs elements, not the .tab-content elements. So in order to tap into the show event, you need the element with an href that is pointed towards #tab1, not the #tab1 content element itself.

So instead of this:

$('#tab1').on('shown.bs.tab', function (e) {
    console.log("tab1");
});

Do this instead:

$('[href=#tab1]').on('shown.bs.tab', function (e) {
    console.log("tab1");
});

Or, to capture all of them, just do this:

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
  console.log(e.target.href);
})

  console.log(e.target.href);

In my case, there was a conflict between Jquery and Bootstrap.

I solved the problem with jQuery.noConflict(). See below!

I hope that helps!

// Issue @ tabs toggle 
jQuery.noConflict();
$(document).on('shown.bs.tab', 'a[data-toggle="tab"]', function (e) {
    alert(e.target.href);
});

If the Tab is dynamic in anyway try using

$(document).on('shown.bs.tab', 'a[data-toggle="tab"]', function (e) {

        alert(e.target.href);
    })
