具体代码如下所示：
<!doctype html>
<html class="no-js">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

<!--[if lte IE 8 ]>

<body style="margin:300px;">
<!-- $('html, body').animate({scrollTop: 0}, '500'); //兼容旧版IE的写法 -->
<div style="height: 2000px;"></div>
<!-- 滚动到顶部 -->
<button data-am-smooth-scroll class="am-btn am-btn-success">滚动到顶部</button>
<!-- 滚动到底部 -->
<button id="doc-scroll-to-btm" class="am-btn am-btn-primary">滚动到底部</button>
<script>
$('#doc-scroll-to-btm').on('click', function() {
var $w = $(window);
$w.smoothScroll({position: $(document).height() - $w.height()});
});
</script>
<!-- 定义选项 -->
<button data-am-smooth-scroll="{position: 57, speed: 5000}" class="am-btn am-btn-danger">慢悠悠地滚到距离顶部 57px 的位置</button>
<!--通过 Data API-->
<!-- 在元素上添加 data-am-smooth-scroll 属性。 -->
<button data-am-smooth-scroll class="am-btn am-btn-success">滚动到顶部</button>
<!-- 如果要指定滚动的位置，可以给这个属性设一个值。 -->
<button data-am-smooth-scroll="{position: 189}" class="am-btn am-btn-secondary">指定滚动的位置</button>
<!--
通过 Javascript
$(window).smoothScroll([options]);
// 滚动到底部
$('#my-button').on('click', function() {
var $w = $(window);
$w.smoothScroll({position: $(document).height() - $w.height()});
});
-->
<div style="height: 2000px;"></div>
</body>
</html>
