Lesson 6: can pass but not functioning


#1

I can pass Next Dot 1, but it will not work in the preview.

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

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

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

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

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

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

});
};

$(document).ready(main);

@askrahn,

+++++ flipboard the next && prev steps

s t e p s - - f o r - - n e x t S l i d e
-1
-1a create a selection of nextSlide (2 steps, capture 'active-slide, capture next() slide )'
-1b create a selection of nextDot
-2 check if selection of nextSlide is EMPTY
-2a if EMPTY change nextSlide selection to first slide
-2b and change nextDot selection to first Dot
-3 swap -active-slide- and -active-dot- class from current to next
Step3 is done by

   currentSlide.fadeOut(600).removeClass('active-slide');
   nextSlide.fadeIn(600).addClass('active-slide');
   currentDot.removeClass('active-dot');
   nextDot.addClass('active-dot');

s t e p s - - f o r - - p r e v S l i d e
-1
-1a create a selection of prevSlide
-1b create a selection of prevDot
-2 check if selection of prevSlide is EMPTY
-2a if EMPTY change prevSlide selection to last slide
-2b and change prevDot selection to last Dot
-3 swap -active-slide- and -active-dot- class from current to prev
Step3 is done by

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

Thanks for the docs.

It seems to be that forgetting the "." before active-slide in

var currentDot = $('active-dot');

is what caused the problem
