我有一个在桌面上工作正常的分屏滑块，但我需要jQuery UI才能在移动设备上工作。可拖动的事件让我来回拖动它，但有时左边的图像从它的原始位置移动，或者完全消失。关于如何处理这个的任何想法？
这是codepen。滑块错误在移动设备上更明显。
document.addEventListener('DOMContentLoaded', function(){
let wrapper = document.getElementById('wrapper');
let topLayer = wrapper.querySelector('.top');
let handle = wrapper.querySelector('.handle');
let skew = 0;
let delta = 0;
if(wrapper.className.indexOf('skewed') != -1){
skew = 1000;
}
wrapper.addEventListener('mousemove', function(e){
delta = (e.clientX - window.innerWidth / 2) * 0.5;
handle.style.left = e.clientX + delta + 'px';
topLayer.style.width= e.clientX + skew + delta + 'px';
});
});
$(".content-wrap").draggable({

dragy: false,

</html>忘记draggable因为它与mousemove事件监听器发生冲突。我已经将touchmove事件监听器用于移动设备。 CODEPEN
wrapper.addEventListener("touchmove", function(e) {
delta = (e.changedTouches[0].clientX - window.innerWidth / 2) * 0.5;
handle.style.left = e.changedTouches[0].clientX + delta + "px";
topLayer.style.width = e.changedTouches[0].clientX + skew + delta + "px";
});
注意：您还可以根据设备类型启用/禁用touchmove和mousemove（触摸与否）。请告诉我这是否有帮助。
