One thing that jumps out at me is that you're using CSS properties as though they were numbers. For instance, you have

top:0;

in your style sheet. This isn't valid CSS, it should be

top:0px;

More on this later. The next thing that I notice is you're using

navbar.style

to get to the style object of the element with id="navbar". this is *not* the right way to do this, and is only supported by IE. To be honest, it's very wrong of IE to even let this work, because it screws up other things sometimes. (Plus, it confuses developers, such as yourself.) The way to get to navbar is not

navbar

but it's

document.getElementById('navbar')

so what you really want is

document.getElementById('navbar').style.left

Finally, you shouldn't just set that value to i. You need to keep it valid css, so make it

document.getElementById('navbar').style.left = i + "px";

And that should work, unless I overlooked something.

(Note that if you read a style property, you're going to get a value like "123px". If you want just the 123, use the parseInt() function, which takes just the numbers at the beginning of a string and returns them as a number.)

It's behaving that way because you're using IE's "document.all" method of accessing the table you want to move around, while newer versions of IE, Mozilla and other standards compliant browsers let you access it via the DOM with "document.getElementById".

So instead of "navbar.style.left" (which IE thinks of as "document.all.navbar.style.left" amd other browsers ignore) you'd use "document.getElementById("navbar").style.left" to make it work in Mozilla & co. You should also add "px" to the changed value for Mozilla to do the right things, like

document.getElementById("navbar").style.left = i + "px";

And BTW... did I really see <font> tags up there? Eek!

Ermmm... seems as if I've been a bit late again.

Just take my previous post as a proof that everything Slime posted is nothing but the truth

kuckus:

Hey, don't dis the <font> tag but skip out on telling us how it's faulty. Now I'm all curious, like George. What would be better to use? Why?

CSS! Font tags have been deprecated since - get this - 1996, in favor of CSS. Even ol' NN4 supports basic font size and color CSS attributes.

There should be some good info on CSS at http://faq.ozoneasylum.com/FaqWiki/shownode.php?id=90&sortby=rating .

I actually use as much CSS as I possibly can except I sometimes put it in a <font> tag...

<font class=?submenu?>blah</font>

Would <span> be a better choice?
Is <font> it self a bad choice for applying CSS?

Yes. If you need to apply style and there doesn't exist a tag that holds the meaning you need, use <span> or <div> instead of <font>. (Never use <font>, ever.)

However, keep in mind that things like

<span class="header">...</span>

should really be

<h1>...</h1>

with CSS properties applied to H1. (The point is to keep the power of HTML. H1 is more descriptive than SPAN.)

Okay, I?ve been messing around with this one.

I changed a few things here and there.

It now works in all the major browser versions I currently have installed. Which would be, IE6.0, NS7.0, Mozilla1.1 and Opera 6.05. I wish there was some way to check pages on older browser versions but I don?t even know were someone would get the outdated versions. I even got it to validate as a XHTML Strict document, served as an XML document.

But as always I had a few problems....

After I uploaded the page then tried to view it in IE, it sort of fell apart. For some reason IE won?t read it from the server correctly yet all the other browsers I have had no problem. But, when I view the page in IE when it's servered from the local drive it's work's correctly.

Also, I wanted to try to make it a PHP file, but I get a parser error because I think the PHP parser tries to parse the XML instructions. I?m not sure if it?s even possible to write a XML document when using PHP. Hell, up until yesterday I didn?t even know what XML was. Hopefully someone else can verify that I actually wrote all this correctly.

Here?s the code for it.....

code:
<?xml version="1.0" encoding="UTF-8"?>

Slime - just a note about unit of measure - you are correct as it relates to his example of course. In your example though, the 'px' is not needed. A value of 0 is valid as is.
