Uncaught TypeError: Cannot read property 'Constructor' of undefined

[gavinju]

When I upgraded from 1.13.12 to the 1.13.14 version, some errors occurred：
“Uncaught TypeError: Cannot read property 'Constructor' of undefined”

I found there is new code in 1.13.14：
// get Bootstrap's keydown event handler for either Bootstrap 4 or Bootstrap 3
var bootstrapKeydown = $.fn.dropdown.Constructor._dataApiKeydownHandler || $.fn.dropdown.Constructor.prototype.keydown;

Please help me, how to solve this problem？
thank you very much！

Bootstrap version
4.3.1

JQuery version
3.4.1

Bootstrap-Select version
1.13.14

OS: Windows 10, macOS

Released in v1.13.15!

using 1.13.18 facing the same issue 👎

Error still occuring.

Just downloaded the last release and the error is still there. Fixed by put the js link at the bottom of the page.

Its caused by bootstrap js(with draggable js) loading after bootstrap-select js

Try include the bootstrap js script (as what I've used from here for bootstrap v4.6). Or use the respective versions that come with the boostrap css's version.

I tried including the bootstrap script and the issue is fixed.

Try to use bootstrap 4.6.0 and try to load bootstrap base files before SELECT plugin js and CSS files.

I'm using Bootstrap 5.1 and loading it before the select plugin. Still, got that issue... any solution?

I can confirm this is fixed by latest bootstrap-select beta2 or beta3
https://cdn.jsdelivr.net/npm/bootstrap-select@1.14.0-beta3/dist/js/bootstrap-select.min.js

In Bootstrap 5.3 I am getting this error:

Uncaught TypeError: can't access property "Constructor", $.fn.dropdown is undefined
bootstrap-select.js:3133
bootstrap-select.js:3152
bootstrap-select.js:21
bootstrap-select.js:23

I am trying to implement the Live Search.

Other scripts that I am using are:

<script src="<cms:show k_site_link />assets/js/jquery-3.0.0.js"></script>
<script src="<cms:show k_site_link />assets/js/popper.js"></script>
<script src="<cms:show k_site_link />assets/js/bootstrap.js"></script>
<script src="<cms:show k_site_link />assets/js/Chart.js"></script>
<script src="<cms:show k_site_link />assets/js/bootstrap-select.js"></script>

and they are in the same sequence as mentioned above.

[maulidailham]
