我正在尝试制作一个对鼠标X位置做出反应的登录页比较滑块，但是我希望滑块移动到与鼠标位置相反的方向。关于如何实现这一点，有什么建议吗？
演示：https://jsfiddle.net/uw5v94qf/
所以基本上，就像演示显示的那样，在我的情况下，滑块跟随鼠标的位置。但我希望它能起到相反的作用(？(，即显示鼠标悬停的当前幻灯片。鼠标向边缘移动得越多，就越能显示特定的幻灯片。

$(function(){
$('.before-wrapper').on( "mousemove", function(e) {
var offsets = $(this).offset();
var fullWidth = $(this).width();
var mouseX = e.pageX - offsets.left;
if (mouseX < 0) { mouseX = 0; }
else if (mouseX > fullWidth) { mouseX = fullWidth }
$(this).parent().find('.comparison-slider').css({
left: mouseX,
transition: 'ease-out'

$(this).find('.after-wrapper').css({
transform: 'translateX(' + (mouseX) + 'px)',

$(this).find('.after-image').css({

您将mouseX指定为从窗口宽度中减去的正常值(e.pageX(
