  • Why be creating an element script passing as attribute a file CSS ?

  • I changed Wéllingthon had put the wrong code

  • See what’s returning on console

  • bootstrap.min.js Failed to load Resource: the server responded with a status of 403 (Forbidden)

  • This using Linux ? This is about permissions. Forbidden that is to say Proibido check the file permissions.

  • I’m using windows

  • Even so, check the access permissions of the directory and file, your code is messy, you are importing 2 times the bootstrap look, you’re using a cdn and importing local. It will not work, either one or the other.

  • then I have to configure the security of bootstrao.min.js ?

  • Let’s go continue this discussion in chat.

Good to several import duplicates in your code, it is necessary to make a clean, I took the liberty to make some changes.

  1. The problem of returning 403 - Forbidden is because the URL

    https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/bootstrap/bootstrap.min.js

    It’s been updated and is now

    https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js

  2. Are you importing the jQuery, Bootstrap and the Font Awesome using CDN, then no need to import location, I removed the lines:

    <script src="js/jquery-1.12.0.min.js" type="text/javascript"></script>
<script src="bootstrap/bootstrap.min.js" type="text/javascript"></script>
<script src="bootstrap/bootstrap.js" type="text/javascript"></script>
<link rel="stylesheet" href="bootstrap/bootstrap.css">
<link rel="stylesheet" href="css/font-awesome.min.css" type="text/css"/>

Getting your code like this.

$('ul.nav li.dropdown').hover(function() {
  $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeIn(500);
}, function() {
  $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut(500);
});
