Execute Method

execute_method.coffee is a coffeescript that makes it possible to execute a method or get a property from a given string

It attaches ExecuteMethod to the window to make it easier to use across libraries. It does check for already existance in case you include it multiple times.

Usage

var Animal;

Animal = {
  type_of_animals: "cows",
  candostuff: function() {
    return "yes";
  },
  cows: {
    first: {
      name: "george",
      dostuff: function() {
        return "eat";
      }
    },
    second: {
      name: "peter",
      dostuff: function() {
        return {
          eat: "grass",
          sleep: "standing"
        };
      }
    },
    third: {
      name: "ole",
      dostuff: function(stuff_todo, should_i_do_it) {
        if (!should_i_do_it) {
          return null;
        }
        return stuff_todo;
      }
    }
  }
};
