[Javascript] Passing data

Thanks, I will take a look at it.
I understand the security problem which is why I was asking if JS has a file
read operation. As it is I am simply looking for a way to pass data in more
more compact form than a long ASCII list of array assignments. Instead of
array[0].x = 22;
array[0].y = 12;
array[1].x = 10;
array[1].y = 5;
array[2].x = 200;
array[2].y = 120;
..... and so on for 1 or 2 meg
or can I find a way to do:
22,12 10,5 200,120 ...and so on for 1 or 200k and then parse it after the
onload event. ( better still as a binary stream)
Thanks

THis is what I assked you to be more precize for.
Because if I understod well, You wan't datda to be read from another file
and to be displayed on youre current page. That is my friend a security
problem that has been very well solved and currently is unbreakable unles
you use some ASP activity, and even some remote Db that is safe. You can't
brake the security protocol.
I have had the same problem and it took me a whole month to find some way
to display newr data in the current window withour having to refresh or
reload the page, correction: moving to another page. The problem was how to
read the data (content) of some <DIV> or <LAYER> object into this page from
another separate file, and pass it as innerText for instance. There is no
simple solution, or no solution at all. But there is a simple work-around.
Pease visit the link above

You will find a simple Test of dinamicity. And how i solved this problem
for IE. /it has a little bug but it works after the second click/
After you view the page go in you're tempIntFolder and find JavaSripts
asociated you have the names in the bottom of the referencial
script tags in the page.
<script language="JavaScript" id=Fili src=""> !
</script>
<script src="anima.js"></script>
<script src="paleta.js"></script>
<script src="pullat.js"></script>
<script src="dinamika.js"></script>
<script src="lokatori.js"></script> !
And also the text files named Fajlli.txt with prefix 1, 2, 3, if you try
to find them with Find files and folders plese specify for example
anima[1].js or for the text file 1Fajlli[1].txt; That are written and
named like JS strings.
And if you have any further question, ask!

Its graphics and animation data to be used with JavaScript functions
that drive DHTM and SVG (Scalable Vector Graphics). It is probably a lot
like Flash and we will output to that as well but I assume Flash uses its
own encoding/decoding format. There is really no limit to how much data you
could have so compacting it as much as possible is important. At this point
we don't want to get into streaming but I suppose there is no reason why the
data could not be sent in packets. At the moment just putting it into a file
(could even be in the HTML or SVG file if that makes sense) and then using a
standard JavaScript operation to read it. Decoding or parsing should not be
a problem for us if we can find and read it.

Hi, Steve!
The problem to know what is you're aim here
What do you wan't to do exactly?
Yes you can put anything in a .txt file. But how do you load it, and
what type of data do you need.
JS has a FileSysObject that can read files, and also write to files.
The split is a command used in strings, why do you need it for?
Be more specific!
Regards

I am not familiar with Split() but I assume that it is some type of
string
parser. If so the problem I am trying to figure out is how do I pass
the
data? If I have a SCRIPT in a HTML file how do I include the code or
can I
just put it in a .txt file and read it. Does js even have a Read
File
operation?
I need to get a good reference book.

If you used ASCII and kept your key=value pairs it would make
parsing it out
on the client pretty simple with split().
Just a thought,
