How can I get Bootstrap version via Javascript?

Question

Is there any way to get the Bootstrap version via calling a function? I did some research but couldn't find any way. The version information is included in the comments at the beginning like this:

`/*!

• Bootstrap v3.3.7 (http://getbootstrap.com)
• Copyright 2011-2016 Twitter, Inc.
• Licensed under the MIT license */`

But in case the comments are removed how do I get the bootstrap version? Bootstrap plugins have a version defined in them but I'm looking for the general Bootstrap version, not version of a particular plugin.

Answer 1

The version of each of Bootstrap's jQuery plugins can be accessed via the VERSION property of the plugin's constructor. For example, for the tooltip plugin:

$.fn.tooltip.Constructor.VERSION // => "3.3.7"

src //getbootstrap.com/javascript/#js-version-nums

if you mean from the css, then you have to AJAX the file and .match(/v[.\d]+[.\d]/);
