DIV随滚动条滚动而滚动

    <script type="text/javascript" src="Js/jquery-1.7.2.min.js"></script>
    <script type="text/javascript">
        $(function() {
            $(window).scroll(function() {
                var top = $(window).scrollTop()+200;
                var left= $(window).scrollLeft()+320;
                $("#editInfo").css({ left:left + "px", top: top + "px" });
            });
        });
    </script>

    <div id="editInfo" style="float:left;300px;background-color:#ccc;position:absolute;top:200px;">
        <div>用户名：<input type="text" /></div>
        <div>密码：<input type="text" /></div>
        <div>年龄：<input type="text" /></div>
        <div>备注：<input type="text" /></div>
        <div><input type="button" value="保存" /></div>
    </div>

    记得以前写这样的代码比较麻烦，现在有了JQuery简单多了，就几行代码搞定！
