jQuery is not defined twitter bootstrap

jQuery is not defined twitter bootstrap

I am getting this error that says jQuery is not defined. I want to use twitter bootstrap and jQuery-UI. In my I’ve added the CSS and JS necessary. I noticed that the jQuery-UI page uses 1.9.1 jQuery and the latest version is 1.10.2. So I’m assuming there is some sort of conflict going on. Twitter bootstrap requires jQuery so that might be causing the error. Or perhaps I am doing something wrong.

Solution 1:

Load jQuery before everything else!

<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" />
<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-theme.min.css" />
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

<script src="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>

Solution 2:

This is most likely because of 2 reasons:

  1. You are loading jQuery twice; remove one of them (preferably the older version).
  2. You are loading bootstrap.min.js before loading jQuery (read the documentation here).

What you need to do is:

<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" />
<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-theme.min.css" />
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" />
<script src="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js" />
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js" />

add jquery js file above bootstrap

Solution 4:

I’ve tested this and this order seems to work the best.

  1. Load CSS
  2. Load jQuery
  3. Load Bootstrap
  4. Load jQuery UI
