Uncaught Error: The bootstrap modal plugin does not have its version defined ?!?

[nick123pig]

I've had an app running for a long time, but just started getting this error out of the blue

At first, it was breaking functionality in my app. I then moved data-confirm-modal to the bottom of my application.js and things started working again, but I'm still getting the error in the js console.

Here are all the pertinent files (I think)

Bootstrap introduced the modal version definition with 3.2.0: Modal.VERSION = '3.2.0'
https://github.com/twbs/bootstrap/blob/v3.2.0/js/modal.js#L33

=> Updating to Bootstrap >= 3.2.0 (or adding the VERSION definition) will fix the problem where data-confirm-modal fails to detect the Bootstrap version

[letungit90]

Add

<script>
  $.fn.modal.Constructor.VERSION = "3.2"
</script>

before <script src="/assets/data-confirm-modal.js"></script>

any fix for bootstrap 5.0.0 beta?

[tagliala]

Hi @RailsCod3rFuture , please use #83 for newer bootstrap support

Hi I had upgraded to rails 5.2.8.1 from rails 4.2.11.
I too saw this error in browser console.

I was on v 1.6.3 of "data-confirm-modal" gem which was doing version check.
I downgraded to v 1.5.0 which did not have version check.

Did not saw the error. And also modal looked ok.

Thank you.
