How can I get bootstrap version via javascript?

回答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 yu ahve to AJAX the file and .match(/v[.\d]+[.\d]/);
