将鼠标悬停在RTL方向页面上水平滚动滚动溢出div

Question

以下代码用于将div左右悬停时自动水平滚动带有溢出的div。

当我在从右到左的RTL（阿拉伯语）网页上应用此代码时，该代码不起作用，我们能否确定如何使其起作用？

我还需要学习如何使其滚动速度变慢。

HTML

<div class="carousel-frame" id="carousel1">
  <ul>
    <li class="carousel-item">
      <img src="http://placehold.it/200x150" />
    </li>

    </li>
  </ul>
</div>

CSS

.carousel-frame {
    width: 100%;
    margin-bottom: 0.5em;
    padding-bottom: 1em;
    position: relative;
    overflow-x: scroll;
    white-space: nowrap;
 }
 .carousel-frame ul {
    margin: 0;
    padding: 0;
    height: 100%;
    list-style: none;
}
.carousel-frame li.carousel-item {
    cursor: pointer;
    display: inline-block;
    margin: 0 5px 0 0;
    padding: 0;
}

JQUERY

$.fn.make_carousel = function() {
var speed = 0;
var scroll = 0;
var container = $(this);
var container_w = container.width();
var max_scroll = container[0].scrollWidth - container.outerWidth();
var prev_frame = new Date().getTime();
container.on('mousemove', function(e) {
    var mouse_x = e.pageX - container.offset().left;
    var mouseperc = 100 * mouse_x / container_w;
    speed = mouseperc - 50;
}).on ( 'mouseleave', function() {
    speed = 0;
});

function updatescroll() {
    var cur_frame = new Date().getTime();
    var time_elapsed = cur_frame - prev_frame;
    prev_frame = cur_frame;
    if (speed !== 0) {
        scroll += speed * time_elapsed / 50;
        if (scroll < 0) scroll = 0;
        if (scroll > max_scroll) scroll = max_scroll;
        container.scrollLeft(scroll);
    }
    window.requestAnimationFrame(updatescroll);
}
    window.requestAnimationFrame(updatescroll);
}

    $("#carousel1").make_carousel();
    $("#carousel2").make_carousel();
