javascript - 在 2 个不同的 div 中滚动垂直文本

Question

我想在启动页面时滚动 2 个 div。我将事件添加到 onload，但它停在这里:

var cross_marquee=document.getElementById(marque)
cross_marquee.style.top=0

有人可以帮助我吗？

代码是:

var delayb4scroll=2000
var marqueespeed=1
var pauseit=0

var copyspeed=marqueespeed
var pausespeed=(pauseit==0)? copyspeed: 0
var actualheight=''
var actualheightDiv2=''

function scrollmarquee(){
if (parseInt(cross_marquee.style.top)>(actualheight*(-1)+8))
cross_marquee.style.top=parseInt(cross_marquee.sty le.top)-copyspeed+"px"
else
cross_marquee.style.top=parseInt(marqueeheight)+8+ "px"
}

function initializemarquee(marque, container){
var cross_marquee=document.getElementById(marque)
cross_marquee.style.top=0
marqueeheight=document.getElementById(container).o ffsetHeight
actualheight=cross_marquee.offsetHeight
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)
}

window.onload=initializemarquee('wtvmarquee', 'wtmarqueecontainer')
window.onload=initializemarquee("wtvmarqueeDiv2", "wtmarqueecontainerDiv2")

Answer 1

您正在覆盖 onload 事件。

创建一个初始化两个选取框的函数:

window.onload = function(e)
{
  initializemarquee('wtvmarquee', 'wtmarqueecontainer');
  initializemarquee("wtvmarqueeDiv2", "wtmarqueecontainerDiv2");
}

此外，不应该是 cross_marquee.style.top="0px" 吗？
