方法原理：
（1）使用jQuery CSS 操作 - scrollTop() 方法，设置 <div> 元素中滚动条的垂直偏移，语法：$(selector).scrollTop(offset)；
（2）若要控制滚动条水平偏移，请使用方法scrollLeft()，语法：$(selector).scrollLeft(offset)；
其中selector表示选择器，offset表示偏移量。

<script type="text/javascript">
$(document).ready(function(){
$(".btn1").click(function(){
$("#test div").scrollTop(100);
});
$(".btn2").click(function(){
alert($("div").scrollTop()+" px");
});
});
</script>
</head> <body>
<div id="test">
