【问题描述】：
我有一个内容编辑器 Web 部件，我在其中使用滚动 Javascript 来显示文本。我需要在保持滚动的同时查询我的新闻部分及其所有文章。我知道我可以对链接进行硬编码，但我希望不必在每次经理添加新闻时都输入新链接。是否有可能做到这一点？或者在另一端，是否可以将内容查询 Web 部件编辑为垂直滚动？
谢谢。
我的 Javascript 是：
<style type="text/css">
#marqueecontainer{
position: relative;
width: 200px; /*marquee width */
height: 200px; /*marquee height */
background-color: white;
overflow: hidden;
border: 3px solid white;
padding: 2px;
padding-left: 4px;
}
</style>
<script type="text/javascript">

var delayb4scroll=2000 //Specify initial delay before marquee starts to scroll on page (2000=2 seconds)
var marqueespeed=1 //Specify marquee scroll speed (larger is faster 1-10)
var pauseit=1 //Pause marquee onMousever (0=no. 1=yes)?

var copyspeed=marqueespeed
var pausespeed=(pauseit==0)? copyspeed: 0
var actualheight=''
function scrollmarquee(){
if (parseInt(cross_marquee.style.top)>(actualheight*(-1)+8)) //if scroller hasn't reached the end of its height
cross_marquee.style.top=parseInt(cross_marquee.style.top)-copyspeed+"px" //move scroller upwards
else //else, reset to original position
cross_marquee.style.top=parseInt(marqueeheight)+8+"px"
}
function initializemarquee(){
cross_marquee=document.getElementById("vmarquee")
cross_marquee.style.top=0
marqueeheight=document.getElementById("marqueecontainer").offsetHeight
actualheight=cross_marquee.offsetHeight //height of marquee content (much of which is hidden from view)
if (window.opera || navigator.userAgent.indexOf("Netscape/7")!=-1){ //if Opera or Netscape 7x, add scrollbars to scroll and exit
cross_marquee.style.height=marqueeheight+"px"
cross_marquee.style.overflow="scroll"
return
}
setTimeout('lefttime=setInterval("scrollmarquee()",30)', delayb4scroll)
}
if (window.addEventListener)
window.addEventListener("load", initializemarquee, false)
else if (window.attachEvent)
window.attachEvent("onload", initializemarquee)
else if (document.getElementById)
window.onload=initializemarquee
</script>
<div id="marqueecontainer" onMouseover="copyspeed=pausespeed" onMouseout="copyspeed=marqueespeed">
<div id="vmarquee" style="position: absolute; width: 98%;">
