I went through the Codecademy flipboard tutorial which basically just shows you how to put a .js file together for a carousel. I took the code from the website and created files on my computer.

I'm saving them as separate files on my computer in one folder. I've tried both pointing the file to a js file I downloaded from the js website (that I placed in the same folder) AND I tried using the website Codecademy provided as the source so I don't think that's the issue. I have each of the files saved separately as app.js, index.html, and style.css.

When I run it, it looks as it should but the the carousel isn't working. However, if I run it on Codecademy it runs perfectly. What gives? I'm just trying to understand the carousel fully and the interaction between .js .html and .css I'm also trying to build my own resume type website with a carousel but I can't do that until I fully understand each of these parts. Something Codecademy fails to do in my eyes.

app.js

    var main = function() {
      $('.dropdown-toggle').click(function() {
        $('.dropdown-menu').toggle();
      });

      $('.arrow-next').click(function() {
        var currentSlide = $('.active-slide');
        var nextSlide = currentSlide.next();

        var currentDot = $('.active-dot');
        var nextDot = currentDot.next();

        if (nextSlide.length === 0) {
          nextSlide = $('.slide').first();
          nextDot = $('.dot').first();
        }

        currentDot.removeClass('active-dot');
        nextDot.addClass('active-dot');
      });

      $('.arrow-prev').click(function() {
        var currentSlide = $('.active-slide');
        var prevSlide = currentSlide.prev();

        var currentDot = $('.active-dot');
        var prevDot = currentDot.prev();

        if (prevSlide.length === 0) {
          prevSlide = $('.slide').last();
          prevDot = $('.dot').last();
        }

        currentSlide.fadeOut(600).removeClass('active-slide');
        prevSlide.fadeIn(600).addClass('active-slide');

        currentDot.removeClass('active-dot');
        prevDot.addClass('active-dot');
      });
    }


    $(document).ready(main);

    Do you have the file `jquery-1.11.1.min.js` in the same folder as your shown files? – halex Dec 17 '14 at 21:25
  • so you have an index.html, app.js and style.css. you have included the style.css, jquery.min.js and app.js inside the index.html. Now the way you have done the code snippet is all wrong. – Sai Dec 17 '14 at 21:25
  • Have a look at your browser's Network panel to see if everything is loaded OK. Also, do you get any JavaScript errors? (+1 for a well formatted question featuring what you have tried). – halfer Dec 17 '14 at 21:26

    @Sai, if you are of the view that someone has done something "all wrong", it is helpful (and customary) to explain why you think that. – halfer Dec 17 '14 at 21:28
  • @halfer- I am trying to create a proper fiddle of the code provided as we speak and trying to make sense of the question and where the OP may have gone wrong myself. I know the OP is new to site so i dont blame that person. No disrespect meant to OP – Sai Dec 17 '14 at 21:29

    Here is the fiddle link http://jsfiddle.net/xt6vbt9q/ . I think i added all external resources (not sure) – Sai Dec 17 '14 at 21:32
  • @halex Yes, it's in the same folder as the other files. – GCQ Dec 19 '14 at 16:59
  • @Sai, one of your`
  • `has the class `dropdown`, but this class does not exist, where is it defined? For me the Menu does not work either
