Where can I declare Global Variables

[rick]

Noob problem. I prefer to keep all my scripts in an external '.js' file.
I am currently loading the external '.js' file from the header. Problem is I
would like to declare
a global variable in the external file, but I keep getting an error about
the object does not exist.

Can someone tell me where or how to declare a global variable in an external
file that is
available after the page is loaded.

Thanks in advance.

I found the answer: Do not use 'var' to declare the variable.
Just declare it!! i.e. 'newvar = 0;'

That shouldn't make a difference, if the declaration is not inside a
function body. Then the declaration will declare the global variable,
just as simply assigning to an undeclared variable.

That is what I did. Sorry still learning..........

I think rick is right, declaring a variable without using "var" inside a
function makes the variable global, at least it looks that way to me.

He is, and Lasse agreed: "...assigning to an undeclared variable". That
is, a variable without prior use of var. It's also described in Netscape's
JavaScript Guide:
