js 用firefox的firebug报错误Event.observe is not a function

firebug显示错误是Event.observe is not a function
请问为什么

<script src="js/fabtabulous.js" type=text/javascript></script>

<script type=text/javascript>

var initialtab = [1, "sc1"]

var previoustab = "";
var intv;

function expandcontent(cid, aobject)
{
stopTimer();

highlighttab(aobject)

if (previoustab != "")
document.getElementById(previoustab).style.display = "none"

document.getElementById(cid).style.display = "block"
previoustab = cid
}

function highlighttab(aobject)
{
stopTimer();

if (typeof tabobjlinks == "undefined")
collectddimagetabs()

for (i = 0; i < tabobjlinks.length; i++)
tabobjlinks[i].className = ""

aobject.className = "current"
}

function collectddimagetabs()
{
var tabobj = document.getElementById("ddimagetabs")
tabobjlinks = tabobj.getElementsByTagName("a")
}

function do_onload()
{
collectddimagetabs()
expandcontent(initialtab[1], tabobjlinks[initialtab[0] - 1])
}

function startTimer()
{
intv = setTimeout("expandcontent(initialtab[1], tabobjlinks[initialtab[0]-1])", 2000);
}

function stopTimer()
{
clearTimeout(intv);
}

Event.observe(window, 'load', do_onload, false);//错误出现在这一行
Event.observe('xcx_tabmenu', 'mouseover', function(event)
{
stopTimer();
}, false);

Event.observe('xcx_tabmenu', 'mouseout', function(event)
{
var reltg = (event.relatedTarget) ? event.relatedTarget : event.toElement;

var tg = (window.event) ? event.srcElement : event.target;

if (tg.nodeName != 'div')
return;

while (reltg != tg && reltg.nodeName != 'body')
{
reltg = reltg.parentNode;

if (reltg.id == "xcx_tabmenu")
return;
}

if (reltg == tg)
return;

stopTimer();
startTimer();
}, false);
</script>

Answer 1

Event.observe(window, 'load', do_onload, false);//错误出现在这一行

前面加个this

this.Event.observe(window, 'load', do_onload, false);

Answer 2

Event.observe 是prototype框架的事件注册函数。
原因可能是你没引入prototype框架的文件。

Answer 3

事件，OBSERVE不是一个（可调用）函数。
你不具体说明干什么出现这样的错误，不好解决。重装可能会解决。
