Meaning of some javascript I am seeing in my logs

[Joshua Beall]

Hi All,

I just noted the following page request in my logs:

/pages/blog/focus.php?ID=15%20onmousedown="return%20clk(1,this)"

The part that beings %20 is foreign to me. Everything before that is valid
and common in my logs, but I do not know what the javascript portion is
about. Can anyone enlighten me? I did a little google searching and I
think it might be some sort of outbound link checking? For this particular
request there was no http referer listed.

Thanks!

%20 is Hex 20 which converted to decimal is character 32 which is a space.
It is placed in a URL in the place of a space.
I'm quite sure I've also seen the %xx used for other characters at time too!

Also, I think from the text you included, you may be missing a quotemark or
something.
You may have something like
ID="15 onmousedown...
instead of
ID="15" onmousedown...

The %20 is only a different way of writing a SPACE. It is in fact an ASCI
hexadecimal code. The % is used in the URL to ascape the code.

So all it means is:

pages/blog/focus.php?ID=15 onmousedown="return clk(1,this)"

If you want to read a bit more on URL codes, have a look at this one:

I think he understands that. What he wants to know is, what is the other
garbage about?
It don't take no rocket scientist to figure out that %20 means a space.

From what I've seen, it appears to be some sort of outbound tracking
routine.

Yeah, I reread what I wrote, and it is not very clear, but I know what %20
means, and I am familiar with escape codes. I just want to know exactly
what the javascript portion is about. Sorry for the lack of clarity.

I was guessing something like this, I was just hoping someone could explain
to me how it works. Anybody?

Here is a nice article on the function used by Google:
