This error message is arising from the following code:
$.fn.extend({
chosen: function(options) {
if ($.browser.msie && ($.browser.version === "6.0" || $.browser.version === "7.0")) {
From the file: https://github.com/koenpunt/chosen/edit/master/chosen/chosen.jquery.js
Obviously browser is not defined. Any idea what could be causing this. Same error in Chrome and FF.
This question is related to
javascript
jquery
$.browser
was removed from jQuery starting with version 1.9. It is now available as a plugin. It's generally recommended to avoid browser detection, which is why it was removed.
