要实现jQuery ScrollLeft，请使用jQuery Easing插件。缓动插件用于动画。
您需要首先添加Easing Plugin库。让我们添加CDN：
script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-easing/1.4.1/jquery.easing.compatibility.min.js"></script>
您可以尝试运行以下代码以轻松实现jQuery ScrollLeft：
<!DOCTYPE html>
<html>
<head>
<script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-easing/1.4.1/jquery.easing.compatibility.min.js"></script>
<script>
$(document).ready(function() {
$("#button1").click(function() {
jQuery.easing.def = 'easeOutBounce';
$('#test').animate({"margin-left": '100'}, 'slow');
});
});
</script>
<style>
#test {
width:150px;
height:150px;
background-color:#6C220A;
}
</style>
</head>
<body>
<div id="test"></div>
<button id="button1">Scroll</button>
</body>
</html>
