Menu
I've just finished constructing my carousel slider with touch events for a website I'm building. Currently trying to figure out how I can disable the touch events(hammer) using on click events. Here is the code that I've been working on
The class .slider-layout enables the carousel while the class .tile-layout disable the carousel and transforms the layout in a card view layout
Update #1
I tried removing the class that binds the hammer.js but didn't work.
var activeSlide = 0;
$('.faculty-carousel').attr('data-slide', '0');
$('.tile-layout').on('click', function() {
$('.faculty-items').each(function() {
$(this).addClass('tile-view');
})
})
$('.prev').on('click', function(e) {
event.stopPropagation();
var carouselWrapper = $(this).closest('.faculty-carousel'),
facultyProfilePanel = carouselWrapper.find('.faculty-items li'),
facultyProfileCount = facultyProfilePanel.length,
viewPortSize = $(window).width(),
carousel = carouselWrapper.find('.faculty-items'),
position = 0,
currentSlide = parseInt(carouselWrapper.attr('data-slide'));
// Check if data-slide attribute is greater than 0
if (currentSlide > 0) {
// Decremement current slide
currentSlide--;
// Assign CSS position to clicked slider
var transformPercentage = -1 * currentSlide / facultyProfileCount * 100;
carousel.css('transform', 'translateX(' + transformPercentage + '% )');
// Update data-slide attribute
carouselWrapper.attr('data-slide', currentSlide);
activeSlide = currentSlide;
}
});
$('.next').on('click', function(e) {
event.stopPropagation();
// store variable relevent to clicked slider
var carouselWrapper = $(this).closest('.faculty-carousel'),
facultyProfilePanel = carouselWrapper.find('.faculty-items li'),
facultyProfileCount = facultyProfilePanel.length,
viewPortSize = $(window).width(),
carousel = carouselWrapper.find('.faculty-items'),
position = 0,
currentSlide = parseInt(carouselWrapper.attr('data-slide'));
// Check if dataslide is less than the total slides
if (currentSlide < facultyProfileCount - 1) {
// Increment current slide
currentSlide++;
// Assign CSS position to clicked slider
var transformPercentage = -1 * currentSlide / facultyProfileCount * 100;
carousel.css('transform', 'translateX(' + transformPercentage + '% )');
// Update data-slide attribute
carouselWrapper.attr('data-slide', currentSlide);
activeSlide = currentSlide;
}
})
function touchCarousel() {
$('.faculty-carousel .faculty-items').each(function() {
// create a simple instance
// by default, it only adds horizontal recognizers
var direction,
touchSlider = this,
mc = new Hammer.Manager(this),
itemLength = $(this).find('li').length,
count = 0,
slide = $(this),
timer;
var sliderWrapper = slide,
slideItems = sliderWrapper.find('li'),
//slider = sliderWrapper.find('li'),
totalPanels = slideItems.length,
currentSlide = parseInt(sliderWrapper.attr('data-slide'));
// mc.on("panleft panright", function(ev) {
// direction = ev.type;
// });
mc.add(new Hammer.Pan({
threshold: 0,
pointers: 0
}));
mc.on('pan', function(e) {
var percentage = 100 / totalPanels * e.deltaX / window.innerWidth;
var transformPercentage = percentage - 100 / totalPanels * activeSlide;
touchSlider.style.transform = 'translateX( ' + transformPercentage + '% )';
var sliderWrapper = $(e.target).closest('.faculty-carousel')
if (e.isFinal) { // NEW: this only runs on event end
var newSlide = activeSlide;
if (percentage < 0)
newSlide = activeSlide + 1;
else if (percentage > 0)
newSlide = activeSlide - 1;
goToSlide(newSlide, sliderWrapper);
}
});
var goToSlide = function(number, sliderWrapper) {
if (number < 0)
activeSlide = 0;
else if (number > totalPanels - 1)
activeSlide = totalPanels - 1
else
activeSlide = number;
sliderWrapper.attr('data-slide', activeSlide);
touchSlider.classList.add('slide-animation');
var percentage = -(100 / totalPanels) * activeSlide;
touchSlider.style.transform = 'translateX( ' + percentage + '% )';
timer = setTimeout(function() {
touchSlider.classList.remove('slide-animation');
}, 400);
};
});
}
function panelSizing() {
// var activeSlide = 0;
// $('.faculty-carousel').attr('data-slide', '0');
var viewPortSize = $(window).width(),
carouselWrapper = $('.faculty-carousel')
;
//Set Panel Size based on viewport

carousel.outerWidth( profilePanelSize * profileCount );

In order to disable touch events make a use of off function.
I've added another link for this action:
$(".toggle-touch-events").click(function() {
mc.touchEvents = !mc.touchEvents;
if (mc.touchEvents) {
mc.on('pan', onPanEvent);
} else {
mc.off('pan');
}
});
