javascript - jQuery blatantly ignoring the path I give to .getScript()

I have a script, TemplateLoader.js which loads 2 Mustache templates, and renders them on the page (or at least that's the goal).

My directory structure:

COMP266
    Unit 4
        scripts
            mustache.min.js

            TemplateLoader.js
        PageUsingTemplateLoader.html

Inside of TemplateLoader (the object), I have the following chunk to load Mustache, and render the templates:

$.getScript("./scripts/mustache.min.js", function() {
    $('head').html( Mustache.render(headTemplate, data) );
    $('body').html( Mustache.render(bodyTemplate, data, uniqueBodyTemplate) );
});

This however, yields the following error in the developer console:

HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier).
(XHR): GET - http://localhost:63342/COMP266/Unit%204/mustache.min.js?_=1450903391318

Oddly, it seems to have dropped the script folder completely from the path.

I decided to play around, so I changed the fetch path to (duplicating the script folder):

./scripts/scripts/mustache.min.js

But this yields:

HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier).

(XHR): GET - http://localhost:63342/COMP266/Unit%204/scripts/scripts/mustache.min.js?_=1450903743022

Now it's listening! Unfortunately, this is obviously the wrong path.

I have no idea how to go about debugging this. It seems like jQuery is selectively dropping the scripts folder. That seems ridiculous, but just to make sure, I searched through the jQuery source, and couldn't find anything that would be doing the observed filtering of the path.

It's currently local, not hosted.

Can anyone give me a hint about what's going on here?

Answer

It turns out the issue was caused by me forgetting that my template added the mustache script (from a previous test), resulting in it being added twice.

I don't understand how this affected it though. It's not like the jQuery addition was succeeding while the template addition was causing the error, since changing the jQuery fetch path caused a direct change in the error message.

Sure enough though, when I removed the script import from the template, it worked.

I really don't understand how this caused a specific folder to be dropped from the path though.
