最简单的层随滚动条滚动

  在网上看了好多关于层随滚动条滚动的文章,感觉不是太理想。就自己试着写了个。
  JS部分只需要这两行就可以三行就OK了。其中的Top 200px等属性根据自己的需要设置,可以设成margin等属性。具体就不写了。

<SCRIPT LANGUAGE=”JavaScript”>
<!–
 function gun(){
 document.getElementById(‘gdt’).style.top=document.documentElement.scrollTop+’px’;
 }
 setInterval(“gun()”,500);
//–>
</SCRIPT>

  特别说明:document.documentElement.scrollTop 关于scrollTop的使用,请到本博客《滚动条的位置:scrollTop的使用》一节查看详细。
