Hi,
I have a page with several javascripts in it.  For some reason I can't
seem to pass variables between the scripts and I need to for one of
the functions.

I understand this can be done by giving each script a name and
referencing the script name with the variable.
Could you provide an example of this, 
or another method of passing variables between scripts.

Thanks,
Martin

Hi mhffs,
Are the scripts declared in the body of your page?  If you declare all
your functions in the head of your page, then they should be able to
pass variables around each other.

It doesn't seem to work.  Let me clarify.

I have a button that sends the user to a url:
www.someweb.com?variable= X
X is a product of a script that runs after the page has loaded and
changes depending on what the user selections are.

function calc(){
var x = (variable1 / variable2);
}
function userInput1(){
 variable1 = adb;
}
function userInput2(){
 variable2 = arnd;
}

What isn 't working is passing "variable1" from "userInput1" to
"calc()"

HELP!!!

Hello mhffs,

I believe I see your problem: like some other languages, JavaScript
has a notion of 'scope' (although quite a quite limited one in
comparison). If you declare a variable inside of one function is JS,
you can't use it in another function. The simple work around is to
declare all variables 'globally' (often considered bad style in other
languages, but pretty common in JS). Alternatively, you could make the
two helper functions return values and call them from calc, but the
other way is probably more straight forward for you. Make the
following simple change and your script should work:

<SCRIPT Type="text/javascript" Language="JavaScript">
<!--
var variable1;  // declare the variables outside of the functions
var variable2;

function calc(){ 
var x = (variable1 / variable2); 
}
function userInput1(){ 
 variable1 = adb; 
}
function userInput2(){ 
 variable2 = arnd; 
}
//-->
</SCRIPT>

Please don't hesitate to ask for a clarification if you need more
help.
