why using node in DOM has problem in IE but not in FireFox?

What’s wrong with the following code? It shows nothing in IE but working fine in FireFox. Is there another way to get around with it?

[CODE]…
<script type=”text/javascript” src=”library/control.js?”></script>
<script language=”JavaScript” type=”text/javascript”>
<!–
function runonload(){
refreshCart(); //in control.js
tnode = document.createElement(“a”);
tnode.setAttribute(“href”, “index3e3.php”);
tnode.setAttribute(“target”, “mainFrame”);
tnode.appendChild(document.createTextNode(“oooo3otto”));
ele = parent.mapFrame.document.getElementById(“map”);
while (ele.hasChildNodes()){
ele.removeChild(ele.lastChild);
}
ele.appendChild(tnode);
}
//–>
</script>
<link rel=”stylesheet” href=”library/computek.css” type=”text/css” />
<title>Untitled Document</title>
</head>
<body onload=”runonload()”>
…[/CODE]

Brendan?

You could also try appending the text node after you append the link to #map.

tnode.setAttribute("href", "index3e3.php");

tnode.setAttribute("target", "mainFrame");

try

tnode.href="index3e3.php";

tnode.target="mainFrame";

but this wont work in FF ?

just make some browser detection

Look for the problem in refreshCart() or perhaps using the onload handler twice.

@ccp999authorOct 17.2005 — Even I changed it to the dot form as followed, IE still display nothing!
<i>
</i>function runonload(){
tnode = document.createElement("a");
tnode.href = "index3e3.php";
tnode.target = "mainFrame";
tnode.appendChild(document.createTextNode("oooo3otto"));
ele = parent.mapFrame.document.getElementById("map");
while (ele.hasChildNodes()){
ele.removeChild(ele.lastChild);
}
ele.appendChild(tnode);
}

In FF, everthing is still working perfectly!

@KravvitzOct 17.2005 — Have you made sure that IE is correctly accessing the frame?

@ccp999authorOct 17.2005 — IE gave me an error notice which said that on the line:

" ele.appendChild(tnode);"

at char 2 has "Invalid argument" with "Code 0".

I'm sure IE is correctly accessing the frame.

@KravvitzOct 17.2005 — Hmm... Have you tried appending the text node to tnode after you appended tnode to ele?

@ccp999authorOct 17.2005 — Hey, it works after I put "parent.mapFrame" on everthing. Thanks all of you!
