How do you create javascript functions that are available project-wide in Ruby on Rails?

Question

I put the following function in my application.js:

function test() {
  alert(\"See Me\")
}

I noticed your function test() is indented, which suggests it is nested. If you define a function in the scope of another function, it will not be available outside of it.

For example this should work, using jQuery:

function test() { /* do something */ }

// another file or inline script

$(function() {
   test();
});

But this won't

(function() {
   function test() {}
})();

// another file

test(); // undefined
