What Did I do wrong here?


#1

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

$('.arrow-next').click(function() {
var currentSlide = $('.activeSlide');
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();
prevDot = $('.dot').last();
}
currentSlide.fadeOut(600).removeClass('active-slide');
prevSlide.fadeIn(600).addClass('active-slide');

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

});

@nizowosa,

The structure of the =main= function should look like

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
};

And the =main= function should be executed when the document is fully loaded and READY

$(document).ready( main );
