  1.   

    window.onscroll=function(){
            alert(document.scrollTop);
    }
      

  2.   

    有专门的scroll的对象的
    scrollTop
    scrollLeft
    参见msdn的帮助

  3.   

    不行啊，我在ie6中，调用的结果是undefined
      

  4.   

    我是这么写的
    <div id ="out">
    <div><img src="1.jpg"/></div>
    <div><img src="1.jpg"/></div>
    <div><img src="1.jpg"/></div>
    </div>js代码：
    $("out").scrollTop;
    alert 出来的结果是0
