Hi all!
I dymically replace the child nodes of a DIV element by image nodes. In
IE and Firefox this works properly. In Safari it works properly, too -
but only if the site is called locally, eg. with file://. Uploading to a
server and viewing the site in Safari with http:// results in an error.
The problematic code is the following:
var node = document.create Element("img");
node.setAttribu te("src", filename);
node.setAttribu te("style", "position:absol ute;left:100px; "); // error
document.getEle mentById(name+" Images").append Child(node);
When executing this script on Safari in online mode (again: with a
_local_ file, it works fine!), Safari reports the following error,
occuring in the marked line:
"[592] :TypeError - No default value"
Obviously, node.style seems not available at this point. I think
Safari's still loading the image, and while loading it blocks all
accesses to node.
Is this assumption correct?
That would mean that in Safari, I cannot do _anything_ with the image
node until the image is loaded. These are not really bright prospects.
Regards,
-.Lutz.-
PS: I tried to enclose the image nodes in DIV elements and to apply
style properties to the DIVs. That lead to a DOMException 8 ("node does
not exist") when calling appendChild(nod e). 2 2076

Sorry, I can't test this right now but... if your assumption is
correct, modifying the style before the src attribute should work. That would mean that in Safari, I cannot do _anything_ with the image node until the image is loaded. These are not really bright prospects.

PS: I tried to enclose the image nodes in DIV elements and to apply style properties to the DIVs. That lead to a DOMException 8 ("node does not exist") when calling appendChild(nod e).
var node = document.create Element('img');
node.alt = 'Picture of something';
node.style.posi tion = 'absolute';
node.style.left = '100px';
document.getEle mentById(name + 'Images').appen dChild(node);
node.src = filename;
Generated elements should comply with HTML 4 (or whatever DOCTYPE
you're using), so you need an 'alt' attribute too.

No it doesn't.

Thanks for the tip.
In the meantime, I found the problem cause: the Content-Type header was
not matching the DOCTYPE declaration. IE and Firefox ignored that but
Safari didn't. Now, with matching text/html and HTML 4.01 DOCTYPE,
everything works as expected even with Safari online.
Thank you for the help,

I try to associate DOM nodes with other objects. Assigning custom
properties to DOM nodes works in Firefox and Safari. It also works with
HTML nodes in IE6. However, it appears not to work with XML nodes that
are part of trees returned by XMLHttpRequest. How can I work around this
limitation? For XML nodes, I need to be able to associate at most one
object with each node.
The syntax I am using is

Hi,
I have a treeview which contains nodes of a class (classA) derived from
treenode.
These classA nodes may contain nodes of a class (ClassB) derived from
classA.
The form load populates a imagelist and calls a subroutine that assigns an
image to each node depending on its type.
If I expand a classA node, all is well. ie. I see the classA image on the
classA node and the classB image on the exposed classB node (which is always

I was playing around with canvas support in recent Safari, Mozilla and
Opera (only version 9 preview) but run into issues with Safari related
to the very old DOM Level 0 Image object for preloading images.
When doing e.g.

img.onload = function (evt) {
alert(this);

Hi,
I have tried the following based on suggestions of the best way to
insert JavaScript into a page. This is instead of using eval().
Unfortunately IE says "unexpected call to property or method access"
for the second to last line of my function.
If you know what I've done wrong or how to fix it I would appreciate
the help.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
