无限图像自动收报机动画口吃

标签： javascript jquery html css animation

我使用jQuery的动画来创建一个无限的图像自动收录器 - 原则上这很有效，但动画结结巴巴。在通过各种替代方案（如Velocity）在网上查看（很多）并尝试这些替代方案后，我无法顺利完成工作。我认为问题是由jQuery本身没有充分利用GPU造成的，但我不确定如何解决这个问题。

HTML看起来像这样：

＆＃13;
＆＃13; 
var img;

function imgScroll() {
  img = $(".retailer-scroller .gallery-row img").first();
  var newspeed = 80000 / (40 - (Math.sqrt(img.width()) * 1.65));
  img.animate({
    width: 0,
    padding: 0
  }, newspeed, 'linear', function() {
    img.removeAttr("style");
    img.remove();
    $(".retailer-scroller .gallery-row").append(img);
    imgScroll();
  });
}
$(document).ready(function() {
  imgScroll();
});
＆＃13; 
.retailer-scroller {
  width: 100%;
  height: 70px;
  position: relative;
  overflow: hidden;
  margin: 10px 0;
}
.retailer-scroller .gallery-row {
  min-width: 2000px;
  height: 65px;
  position: absolute;
  left: -500px;
  white-space: nowrap;
  padding: 0;
}
.retailer-scroller .gallery-row img {
  display: inline-block;
}
.img-responsive {
  height: auto;
  max-width: 100%;
}
.retailer-scroller img {
  filter: grayscale(100%);
  max-height: 65px;
  opacity: 0.75;
  padding-left: 50px;
  width: auto;
}
.retailer-scroller img:hover {
  filter: none;
  opacity: 1;
}
＆＃13;

有关如何让这部动画变得更流畅的任何想法？当在页面上使用上面的代码时，它会变慢并变得更加不连贯/跳跃。

非常感谢任何帮助。

经过更多测试和挫折后，我终于找到了这个网站enter link description here，并将我的代码修改为：
