JavaScript Variable Passing between different .js

Question

I am trying to pass 4 variables from one js file to another.

I read here that you must write:

window.myVar = "foo";

to make your variable "super"-global.

In the first js file, I have

window.signJoueur1 = string1.charAt(7);  
window.signJoueur2 = string2.charAt(7);  
window.valeurJoueur1 = random1;  
window.valeurJoueur2 = random2;

In the second js file, I did

console.log(window.signJoueur1);
console.log(window.signJoueur2);
console.log(window.valeurJoueur1);
console.log(window.valeurJoueur2);

function trouveCombinaison(signJoueur1, signJoueur2, valeurJoueur1, valeurJoueur2)
{
console.log(signJoueur1);
console.log(signJoueur2);
console.log(valeurJoueur1);
console.log(valeurJoueur2);
}

It should work, but all console.log return `undefined'.

If you want more informations here are the full codes:
first .js http://pastebin.com/0zJKFNem
second .js http://pastebin.com/TsWc7TxL
the html http://pastebin.com/t3SzwZSC

So, my question is, how can I actually pass through the variables?

Please don't just add a '2' to the title to allow your question to be posted. Come up with a more meaningful title. — George

in trouveCombinaison, it passes as arguments, so that will comes under scope of trouveCombinaison. in that variables has value undefined — rab

You are trying to use the values before they exist.

The code that assigns the values to the variables are inside a function, and that function isn't called until you click a button. The code that tries to show the values is executed when the page loads, so it uses the variables before they have been assigned any values.

Actually i just had to put window. in the second console.log group.

Such as :

function trouveCombinaison()
{
console.log(window.signJoueur1);
console.log(window.signJoueur2);
console.log(window.valeurJoueur1);
console.log(window.valeurJoueur2);
}

The fact that the console.log out of the function don't work is that it's executed when the page loads, as explained by @Guffa.

Now it works.

Why do you even need arguments to that function? They do nothing.
