invalid argument with appendChild

[Andrew Poulos]

If I try to append a PARAM tag twice I'm having problems:


var.medDiv = document.getElementById("myDiv");

var medObj = document.createElement("object");

var p = document.createElement("param");
p.setAttribute("FileName",this.URL);
medObj.appendChild(p);

p = document.createElement("param");
p.setAttribute("AutoStart","false");
medObj.appendChild(p); // <-- this one

medDiv.appendChild(medObj);


The line with the "this one" comment triggers IE to tell me that it has
an invalid argument. If I change the order of the PARAMs then the new
second PARAM will give me the error. If I move the setAttribute to after
the appendChild I still get the error.

I'm unsure what's wrong.

var medDiv...

Perhaps? Loose the '.' between 'var' and 'medDiv'

Dang that was my typing the question out not the code I'm using. That is
the code I'm using does have

var medDiv...

I'm still stuck the second call to appnedChild of a PARAM element
causes IE to choke and I can't fix it.

You aren't setting the attributes properly:

p.name = 'FileName';
p.value = this.URL;

Likewise for the second PARAM element.

When I do setAtribute/appendChild twice it gives me an error in IE 5,
5.5, and 6. If I go the name value pairing/appendChild twice it 'works'
in IE6 but not 5 or 5.5.

I'm beginning to think that IE has trouble with OBJECT tags that are
dynamically added using DOM methods.

Given the above posts, I can only suggest using "var" when declaring
'p' in both instances:

var p = document.createElement("param");
p.name = FileName
[...]

var p = document.createElement("param");
[...]

Alternatively, use a different variable name for the second PARAM
and see if that works.

Thanks. I tried it, and about a million other things, and it made no
difference. I'm seriously starting to believe that IE does not like
people using DOM methods to dynamically create OBJECT tags.

Well I should've looked here in the first place:

It seems the OBJECT tag with appendChild is not supported in IE. Sorry
for wasting people's time.
