9/12 Previous Slide


#1

I can't figure out what's wrong with my code. Can someone help?

Error Message: Oops, try again. Remember to fade out the current slide and remove the 'active-slide' class.

var main=function() {
$('.dropdown-toggle').click(function() {
$('.dropdown-menu').toggle();
});
$('.arrow-prev').click(function() {
var currentSlide= $('.activeSlide')
var prevSlide = currentSlide.prev();
if(prevSlide.length == 0) {
prevSlide = $('.slide').last();
}
currentSlide.fadeOut(600)//.removeClass('active-slide');
prevSlide.fadeIn(600)//.addClass('active-slide');
});
$('.arrow-next').click(function() {
var currentSlide = $('.active-slide');
var nextSlide = currentSlide.next();
if(nextSlide.length == 0) {
nextSlide = $('.slide').first();
nextDot= $('.dot').first();
}
var currentDot=$('.active-dot')
var nextDot=currentDot.next();

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

};
$(document).ready(main);

@jamaljwilson,

++ the build of script ++
Now as a so-called argument of the =click= Eventhandler
you are placing a so-called anonymous function
var main = function() {
//Begin of =main= FUNCTION-BODY
$('.dropdown-toggle').click(function(){
$('.dropdown-menu').toggle();
});

    $('.arrow-next').click( function() {
         //code which gets executed when =click=ed
    });
    $('.arrow-prev').click( function() {
         //code which gets executed when =click=ed
    });
 //End of =main= FUNCTION-BODY

};
$(document).ready( main );

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');
