Cannot dynamically create iframe

[BananaQuaalude]

I'm getting the following error when I try to dynamically create an
iframe:

Error: Expected hexadecimal digit

This only occurs when I try to give the iframe a src value. If I leave
out the src, no error. Any ideas?

Here is the code:

var d=document;
if(d.getElementById && d.createElement && d.body &&
d.body.appendChild && typeof d.body.innerHTML != "undefined") {
var
Block = d.getElementById("childrenBlock"),
index = getLineItemCount();
//alert(index)
var container = d.createElement("div");
container.innerHTML =

"<div id='FileUpload" + index + "' class=Text><iframe frameborder=0
width=100% height=30% " +
"scrolling=no border=0 id='demo' name='demo' src='NewUpload
\upload2\demo.asp'></iframe></div>" +

Block.appendChild(container);

There's quite a bit of code (other form elements) before and after the
iframe I'm trying to create, but if I comment out the iframe, or just
don't give it a src value, I get no errors.

Is this just a simple formatting issue?

Thanks!

var container = d.createElement("div");

You confuse Web and WinDOS which is why you create the start delimiter of a
Unicode character escape sequence -- \u -- that has to be followed by the
hexadecimal code point value of the character.

Always delimit path components in URIs with `/'.

Okay, I understand I need an escape character, but I'm not sure which
one. Did you mean to say "Always delimit path components in URLs" with
`/' instead of "URIs"?

I've tried many combinations of \u and `/' but I still get the same
error. This goes inside the single quote, correct?

Thanks!

What Thomas was saying is that your src path should look like this:

src='NewUpload/upload2/demo.asp'

Using / instead of \

Using backslashes in paths doesn't work on web URI's, and also doesn't
work in JavaScript strings. The \ character is an escape character
giving special meaning to the character that follows. In your example
you've got \u and \d in your string.

If you're receiving your string like that, then you should replace them
using something like this:

s=s.replace(/\\/g,"/");

Wow.

Well, that's what happens when you're coding at the end of a long day.

Thank you both for pointing out the obvious. I needed it!
