declare variables document.write()

[Jean]

function myFunction(){
document.write('var path="../images/2008/');
}
I use this kind of function to declare the variable path. It's on a
extern javascript file. If I use this function in an other function to
define var path, the result is an error: path not defined. Can someone
explain to me why this doesn't work?

Apart from being quite an odd thing to want to do, and probably
considerably more simply (and reliably) achieved by other means), -
document.write - inserts HTML contents into the HTML stream (assuming
the document is not already closed at the time) and in that context
your 'var path="../images/2008/' is just text content (not script
source code (to be the latter it would have to appear in a SCRIPT
element)), and even if that text were interpreted as script content it
would only result in a syntax error as the opening double quote at the
beginning of that appears to have been intended to be a string literal
is not matched with a closing double quote.
