Question

https://codepen.io/douglascat90/pen/KeEaxd

I want to add javascript/css/whatever is needed so that I can slide left or right on mobile with touch and it will change the slide left or right accordingly. What's the best way to do this? I am following along with a codepen made by Damian Drygiel here https://codepen.io/drygiel/pen/rtpnE

<div id="slider1" class="csslider infinity inside">
<input type="radio" name="slides" id="slides_1" checked />
<input type="radio" name="slides" id="slides_2" />
<input type="radio" name="slides" id="slides_3" />
<input type="radio" name="slides" id="slides_4" />
<input type="radio" name="slides" id="slides_5" />
<input type="radio" name="slides" id="slides_6" />

Answer 1

You will need to use JavaScript, adding the touch event listeners, appropriately:

https://developer.mozilla.org/en-US/docs/Web/API/Touch_events

1. Add a touchmove event listener to detect where in relation to the screen the users finger/toe/nose is. Once you have a round number, use the style endpoint , and update margin-left to equal your distance in pixels.

2. Add a second event listener, touchend . With this, detect if the user is over a certain margin of the slider (Eg the user has pushed the content by 30%, update the appropriate input to be checked (current -/+ 1).

A quick start based on the pen you've provided:

const slider = document.getElementById('slider1');
const slides = slider.querySelectorAll('input');

slider.addEventListener('touchmove', (e) => {
  // Add step 1 in here
});

slider.addEventListener('touchend', (e) => {
  // Add step 2 in here
});

Answer 2

I've found a function somewhere, you might change some to get the right results. But I think you can't do it without javascript.

carousel.on('touchstart touchmove touchend', function (e) {
                            touchHandler(e);
});
function touchHandler (event) {
                    var touch
                        , xSwipe
                        , ySwipe;

                    if (typeof event !== 'undefined'){  
                        // for vanilla javascript use event.touches
                        if (typeof event.originalEvent.touches !== 'undefined') {
                            touch = event.originalEvent.touches[0];

                            switch (event.originalEvent.type) {
                                case 'touchstart':
                                case 'mousedown':
                                    _touches[event.originalEvent.type].x = touch.pageX;
                                    _touches[event.originalEvent.type].y = touch.pageY;
                                    break;
                                case 'touchmove':
                                case 'mousemove':
                                    _touches[event.originalEvent.type].x = touch.pageX;
                                    _touches[event.originalEvent.type].y = touch.pageY;
                                    break;
                                case 'touchend':
                                case 'mouseup':
                                    if (!carousel.data('busyAnimating')) {
                                        _touches[event.originalEvent.type] = true;

                                        if (_touches.touchstart.x > -1 && _touches.touchmove.x > -1) {
                                            xSwipe = Math.abs(_touches.touchstart.x - _touches.touchmove.x);
                                            ySwipe = Math.abs(_touches.touchstart.y - _touches.touchmove.y);

                                            if (xSwipe > ySwipe && xSwipe > (getViewport().width * .33)) {
                                                _touches.direction = _touches.touchstart.x < _touches.touchmove.x ? 'left' : 'right';

                                                if (_touches.direction === 'left') {
                                                    moveToSlide('prev');
                                                } else if (_touches.direction === 'right') {
                                                    moveToSlide('next')
                                                }
                                            }
                                        }
                                    }
                                    break;
                            }
                        }
                    }
                }
