$.fn is undefined

[KhoaSydney]

Hi,

I'm currently facing the problem with bootstrap3-dialog using webpack. At runtime, it said $f.fn is undefined. $ is defined and I have tested with alert($) but not .fn. Please note that jQuery and Bootstrap are loaded so libraries dependency is not the cause of this error. Is there anything else that might causes the problem?

Cheers,

Hi,

Is there an online example?

Hi Nakupanda,

Due to complicated setup with Webpack, I can not post it online. I'm thinking this error cause by jQuery conflict. But beside that I can not think of anything else.

Ok,

So please paste the error details here, let's see if we can find something inside.

I have attached an image which desribes the error. As you can see from the right window panel, $ is defined as a jquery. The left panel show where the error occurred.

Sorry this is the only error that I can see. There is no other details.

What bootstrap version you're using ?

[KhoaSydney]

Bootstrap v3.3.4

Should we wrap the factory function in the following format see if it will fix the issue?

function ($) {
  'use strict';
  var version = $.fn.jquery.split(' ')[0].split('.')
  if ((version[0] < 2 && version[1] < 9) || (version[0] == 1 && version[1] == 9 && version[2] < 1)) {
    throw new Error('Bootstrap\'s JavaScript requires jQuery version 1.9.1 or higher')
  }
}(jQuery);

If it doesn't take to too much time I would suggest to do so.

But can you please also provide what jQuery version you're using, and, did you load it prior to bootstrap?

[KhoaSydney]

Ok by wrapping it with (jQuery) fixed the error but I have a new error now. this in this.defaultOptions is null.

[KhoaSydney]

jQuery JavaScript Library v2.1.3.

[nakupanda]

Strange, can't figure it out at this moment

[KhoaSydney]

The second fix is posted in another issue:
#142

in short change
module.exports = factory(require('jquery')(root)); to module.exports = factory

I hope this will be useful for other people who have the same problems.

cheers

Hi Nakupanda,

Would you commit fix for the errors mentioned above so that I don't need to add the fix each time I update the package?

cheers,
Khoa
