Test of code initially failed

The demo here

https://www.jqueryscript.net/demo/Mobile-Drag-Drop-Plugin-jQuery

looked nice so I wanted to try out your code. After downloading your code from github, uploading it to my server, and included the correct files in my code, I discovered it doesn't work. The console says:

Uncaught ReferenceError: define is not defined at draganddrop.js:1

To be clear: I didn't use "Bower", why would I? I've never used it, and there are only two files. I can't find anything concrete on define(), but it seems to me that it is somehow part of "Bower". Could that be true?

I then looked a bit closer at the demo page above, and found that the javascript code there is slightly different. Instead of:

define(['jquery'], function($) {
"use strict";
   .......
});

it uses:

(function($) {
"use strict";
   .......
}(jQuery));

which does seem to work for me. I also saw some other differences in the code, so I copied your github code and used the above piece of code around it. That seems to work fine.

So is this a "Bower" dependency? And why make your code dependent on it? (sorry, I may be old-fashioned, I like to upload the code myself. Makes me feel in control.)

Anyway, now that I have it working I can experiment with it. What I especially like in your demo is the ability to play with nested lists.

PS: The link to the demo page, here on github, goes to the demo source, not a working demo.

Hi, thanks for your feedback. The code is written as a module that can be included into your own code with a tool like require.js or webpack. I have stuck to this convention because it helps me when using the module in my own projects.
If you want to use the code without such a tool you could probably just remove the first and last line of the module and make sure that $ (jquery) is globally available.
Bower is just a dependency management tool that can help you download required libraries for your project. It is not required for this module to work (in fact I don't use it any more at all), it is just a convenience.
Cheers, Ole.
