Previous Dot 1 : Where is my mistake?


#1

The web says: "Oops, try again. It looks like previous arrow isn't moving back to the previous dot. Look back at the instructions and check the $('.arrow-prev').click() event handler."


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();
}

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

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();
}

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

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

});

}

$(document).ready(main)


I donĀ“t know where the mistake is.

Help me, please.

@angelolmos,

+++++ 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');
