比较滑块 – 如何使鼠标位置以相反的方式运行？

Question

我正在尝试制作一个对 mouseX 位置做出反应的着陆页比较滑块，但我希望滑块向鼠标位置的相反方向移动。关于如何实现这一点有什么建议吗？

所以基本上，就像演示所示，在我的例子中，滑块跟随鼠标位置。但我希望它做相反的事情（？），即显示鼠标悬停的当前幻灯片。鼠标向边缘移动的越多，它显示的特定幻灯片就越多。

(function($){
$(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)',
      transition: 'all 1s'
    });
    $(this).find('.after-image').css({
      transform: 'translateX(' + (-1*mouseX) + 'px)',
      transition: 'all 1s'
    });
  });
  $('.slider-wrapper').on( "mouseleave", function() {
    $(this).parent().find('.comparison-slider').css({
      left: '50%',
      transition: 'all .3s'
    });
    $(this).find('.after-wrapper').css({
      transform: 'translateX(50%)',
      transition: 'all .3s'
    });
    $(this).find('.after-image').css({
      transform: 'translateX(-50%)',
      transition: 'all .3s'
    });
  });

});
})(jQuery);

Answer 1

实际上这个小调整就可以解决问题

var mouseX = $(window).width() - e.pageX ;

您将 mouseX 指定为从 window 的宽度

中减去的正常值 (e.pageX)
