Hello!

I was using bootstrap modal with bootstrap.min.js in Scripts directory of my project. Suddenly it stops working...

Not working:

<script type="text/javascript" src="Scripts/bootstrap.min.js"></script>

In this case everything looks to be ok - there is even no error in browse console while loading bootstrap.min.js file - just nothing happened on click...

Working:

<script type="text/javascript" src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>

Files are placed in Scripts folder like always, I tried change file on disk, to this from link - without any reason.

There is no error in browser console, just modal window does not appear. Everything is working only when I change to full URL.

What can be the reason...?

What I have tried:

Few versions of bootstrap files, removing files from Scripts directory with

src="Scripts/bootstrap.min.js"

- then I can see error in browser console (jquery loaded, but can't find .modal function - correct information in this case)

The local script is using a relative source. The file must be in a folder called Scripts within the same folder as the current URL.

For example, if your URL is: https://somesite.local/folder/page1.aspx
Then the script file must be: https://somesite.local/folder/Scripts/bootstrap.min.js

If your URL is: https://somesite.local/folder/sub-folder/page1.aspx
Then the script file must be: https://somesite.local/folder/sub-folder/Scripts/bootstrap.min.js

If the scripts folder is in the root of your application, use an app-relative path:

ASPX

<script src="<%= ResolveClientUrl("~/Scripts/bootstrap.min.js") %>"></script>

If it still doesn't work, then you need to use your browser's developer tools to see why the script file is not loading.
