在htc函数中找不到id？急

[louis_zheng]

在htc里面写
var ele_span = document.createElement("span");
ele_span.id="myspan";
ele_span.style.fontFamily = "Webdings";
ele_span.style.color="#ffffff"
ele_span.height=20
ele_span.style.backgroundColor="#cccccc"
ele_span.style.border="1px solid #cccccc"
ele_span.style.cursor = "hand";
ele_span.innerHTML="6";
ele_span.attachEvent("onmouseover", ButtonOver);
spantd.appendChild(ele_span);

function ButtonOver(){
var tempspan = document.getElementById("myspan");
if(tempspan)
tempspan.style.backgroundColor='#5c5c69'
else
alert("this id is not exist")

}
控件在ie能显示出来了，可是执行buttonover的时候找不到span的id，总是alert,怪异？

var oWindow = window;
var ele_span = oWindow.document.createElement("span");
ele_span.id="myspan";
ele_span.style.fontFamily = "Webdings";
ele_span.style.color="#ffffff"
ele_span.height=20
ele_span.style.backgroundColor="#cccccc"
ele_span.style.border="1px solid #cccccc"
ele_span.style.cursor = "hand";
ele_span.innerHTML="6";
ele_span.attachEvent("onmouseover", ButtonOver);
spantd.appendChild(ele_span);

function ButtonOver(){
var tempspan = oWindow.document.getElementById("myspan");
if(tempspan)
tempspan.style.backgroundColor='#5c5c69'
else
alert("this id is not exist")

}

document.all("myspan");

top.document.getElementById()试试

[zhouguoyao]

var tempspan = document.getElementByName("myspan");
