Hello there, I'm a first time poster but have been reading for a while now. I've been working on creating a simple jQuery Slider and I'm facing an issue... I want to create a slider that utilizes minimal jQuery and can be easily duplicated on the same page to add another slider.
My main challenge right now is getting the second slider to function properly. I tried duplicating the code and tweaking the CSS, but it goes against the principle of D.R.Y (Don't Repeat Yourself).
I am looking to condense the code so that it can serve two unique sliders efficiently. Thanks a lot for any help from the S.O. Community!
jQuery(document).ready(function ($) {
$('#checkbox').change(function(){
setInterval(function () {
moveRight();
}, 3000);
});
var slideCount = $('#slider ul li').length;
var slideWidth = $('#slider ul li').width();
var slideHeight = $('#slider ul li').height();
var sliderUlWidth = slideCount * slideWidth;
$('#slider').css({ width: slideWidth, height: slideHeight });
$('#slider ul').css({ width: sliderUlWidth, marginLeft: - slideWidth });
$('#slider ul li:last-child').prependTo('#slider ul');
function moveLeft() {
$('#slider ul').animate({
left: + slideWidth
}, 200, function () {
$('#slider ul li:last-child').prependTo('#slider ul');
$('#slider ul').css('left', '');
});
};
function moveRight() {
$('#slider ul').animate({
left: - slideWidth
}, 200, function () {
$('#slider ul li:first-child').appendTo('#slider ul');
$('#slider ul').css('left', '');
});
};
$('a.control_prev').click(function () {
moveLeft();
});
$('a.control_next').click(function () {
moveRight();
});
