javascript - 图像作为光标，滚动时应该移动

Question

我用更大的图像替换了我的光标，以便在网站上有一个大光标。实际上，它工作得很好并且跟随鼠标但是一旦我滚动我的页面，光标就会停留在与以前相同的位置并且一旦我再次移动鼠标就会更新。

我的想法是让鼠标在滚动时立即移动，而不是稍后传送。

这是代码，您可以理解。谢谢您的帮助！

  $(document).on('mousemove', function(e){
    $('#custom-cursor').css({
      left:  e.pageX -30,
      top:   e.pageY-25,
            pointerEvents: 'none'
    });
  });

#custom-cursor{
    width: 230px;
    height: 300px;
    position: absolute;
    background-size: 230px 300px;
    background-image: url("https://i.imgur.com/6uh0F5h.png");
}

好吧，您还需要通过滚动距离的量来计算相对鼠标位置，如下所示：

编辑：我只是为垂直滚动做的，你可能还需要为水平滚动做同样的事情。

let lastX, lastY, lastScrolled = 0;;
$(document).on('mousemove', function(e) {
  lastX = e.pageX - 30;
  lastY = e.pageY - 25;
  $('#custom-cursor').css({
    left: e.pageX - 30,
    top: e.pageY - 25,
    pointerEvents: 'none'
  });
});

$(window).scroll(function(event) {
  if (lastScrolled != $(window)
    .scrollTop()) {
    lastY -= lastScrolled;
    lastScrolled = $(window)
      .scrollTop();
    lastY += lastScrolled;
  }
  $('#custom-cursor').css({
    left: lastX,
    top: lastY,
    pointerEvents: 'none'
  });
});

#custom-cursor {
  width: 30px;
  height: 30px;
  position: absolute;
  background-size: 230px 300px;
  background-color: red;
}
