Connecting Bootstrap Tabs Dropdown to Website LinksIncorporating Bootstrap Tabs Dropdown Menu

Having an issue with my dropdown list in the Twitter Bootstrap tab - it's not responding when clicked. I've checked Stackoverflow for solutions but nothing has worked so far. I even tried removing the data-toggle='tab' attribute.

Just a heads up - I'm using Twitter Bootstrap 3.0

Here's the code snippet:

<ul class="nav nav-tabs case-detail-nav" id="myTab">
   <li class="dropdown">
   <a href="#" class="dropdown-toggle" data-toggle="dropdown" data-target="#">Text Files<b class="caret"></b></a>
   <ul class="dropdown-menu" role="menu">
     <li><a href='http://www.google.com/'>google</a></li>
   </ul>
   </li>
   <li class="active"><a href="#general">General</a></li>
 </ul>

And here's the Javascript:

<script>
  $(function () {
    $('#myTab a:last').tab('show')
  })


  $('#myTab a').click(function (e) {
  e.preventDefault()
  $(this).tab('show')
})  
</script>

Any help would be greatly appreciated! Thanks!

Answer №1

The issue at hand pertains to the use of preventDefault on anchor click events, particularly in a dropdown menu scenario where it is not desired. Prior to calling preventDefault(), it's important to perform a validation check. By preventing default behavior on anchor elements and then attempting to display a tab using $(this).tab('show'), Bootstrap interprets the href attribute as a selector for identifying the tab content (this may lead to errors in jQuery Sizzle due to invalid characters in the selector).

 $('#myTab a').click(function (e) {
     if (!$(this).closest('.dropdown-menu').length) { //validate if event originated from dropdown
         e.preventDefault();
         $(this).tab('show');
     }
 });

Alternatively, focus only on authentic tab triggers.

$('#myTab > li > a').click(function (e) {
         e.preventDefault();
         $(this).tab('show');
 });

If you come across a similar issue like this...

My experience was also the same, but I found that removing the data-toggle attribute fixed the problem:

<ul class="dropdown-menu">
    <li><a href="http://www.example.com/" target="_blank" data-toggle="collapse">Another link</a></li>
</ul>

changes to

<ul class="dropdown-menu">
    <li><a href="http://www.example.com/" target="_blank">Another link</a></li>
</ul>
