Accessing variables from other functions without using global variables

by

I think your best bet here may be to define a single global-scoped variable, and dumping your variables there:

var MyApp = {}; // Globally scoped object

function foo(){
    MyApp.color="green";
}

function bar(){
    alert(MyApp.color); // Alerts 'green'
}

No one should yell at you for doing something like the above.
