I am using rails-backbone, coffeescript gems in my rails 3.2.6 project.
square = (x) -> x * x
alert square(5)
this is the blog.js.coffee script file it produces:
(function() { var square; square = function(x) {return x * x;}; alert(square(5));
I need to call the square() method in an other view file.
How can I call that? Is there any thing wrong I am doing?
All your code in Coffeescript will be inside a self-invoking anonymous function.
To call it outside a file, just write:
window.square = (x) -> x * x
alert(square(5)) in an other function
The best you can do to not overuse window is a App object that will contain all your variables.
window.App={}
window.App.square= (x) -> x * x
and then alert(App.square(5))
