I have a page in my site that has a list of stock market indices:

http://www.fiscalstudy.com/major.html

I will use these values on other pages too.

So, I don't want to change exact the same value for a couple of times.

Is it possible to make just one change for one value and get it updated at all other places on the site?

I do not want to update exact the same thing all over again for other pages.

Well, with javascript you can, but it's not very elegant....a server side solution would be better. Nonetheless, here's the JS way...// external js file - 'stocks.js'
var djia = '7286.27';
var nasdaq = '1114.11';
var sp500 = '776.26';Now, with every page that you link to with that JS file, you can write their values to the page...Dow Jones: <script>document.write(djia);</script><br>
NASDAQ: <script>document.write(nasdaq);</script><br>
S&P 500: <script>document.write(sp500);</script><br>Etc etc....

what function should I use for variables? do I just list them?
beetle

Right, just list (define) them. They will all be global variables...

here's how it is:
------------------on the page:

<td align="center"><strong>DJIA</strong></td>
<td align="right"><script language="JavaScript"
src="http://www.fiscalstudy.com/values.js"><!--
document.write(djia)
// --></script><br>

----------------on the external file:

var djia = "7286.27";
var nasdaq = "1114.11";
var sp = "776.26";
var nikkei = "776.26";
var ftse = "776.26";
var dax = "776.26";
var cac = "776.26";
var hang = "776.26";
var amsterdam = "776.26";
var australia = "776.26";
var milan = "776.26";
var new = "776.26";
var singapore = "776.26";
var south = "776.26";
var stockholm = "776.26";
var zurich = "776.26";
var taiwan = "776.26";
var toronto = "776.26";
var vienna = "776.26";
var argentina = "776.26";
var brazil = "776.26";
var chile = "776.26";
var istanbul = "776.26";
var jakarta = "776.26";
var kuala = "776.26";
var mexico = "776.26";
var philippines = "776.26";
var shangai = "776.26";
var thailand = "776.26;

---

but it is still not working. (you may check on the page)

am I missing something?

thank you for your time.

You cannot put any scripting within the block of a script tag that loads an external file. Besides...the document.write() command has to take place in the document at the point you need it written...

so, include the file once...in the <HEAD> and use document.write commands in their own <script> blocks in the page to write your values...

ok....

-------------right in the <head> is:

<script src="http://www.fiscalstudy.com/values.js"></script>

------------and right in the place for the value is:

<script>document.write(djia);</script>


----------and the .js file is exactly the same as before.


but still not working.

there must be something else I am missing.

thanks again. I appreciate it.

there are errors, "Expected identifier". and as a consequence of that, another error appears, "djian undefined". Maybe your browser setting for script error is turned off.

anyway here's the solution:

var thailand = "776.26";

you missed the closing quote.

dear glenn,

yes you are right. error messages were turned off.

but after closing the quote, it still gives the same two errors. I started thinking that it may be sth that has to do with the .js file.

because it somehow cannot define djia.

try renaming the new variable:

var new = "776.26";

it is a keyword in javascript
ssskaya

tried that.

no difference.

so you are sure that, in the .js file, just listing the variables as: var a = "123"; var b = "456";... and so on is all that it takes, right? there should be no functions or document.write() commands, right?
glenngv
10-30-2002, 06:53 AM
yes correct.

but why did you put new in all your variables?!

var new djia = "7286.27";
var new nasdaq = "1114.11";
var new sp = "776.26";

there should be no new there?
who told you to put it?
ssskaya
10-30-2002, 06:59 AM
oh!

I told you were talking about something else!

now I got it! you mean the variable I use for new zealand may be causing a conflict!

looks quite silly, I know :)
