Question

In JavaScript I’d like to take an object and pass a parameter to it and based on the parameter have a method that will pass settings to the parameter:

functionName( parameter , settings );

Or

functionName( parameter ).methodName( settings );

example: for my iPhone web app setup I do heavy(‘setup’,{ icon: ‘icon.png’ }); and I want to move the second parameter to a method: heavy(‘setup’).settings({ icon: ‘icon.png’ }); for my ease and learning…

Answer 1

Do you mean something like this?

heavy = function() {
  var _settings;

  return {
    setup: function (settings){
      this._settings = settings;
    },

    getSetting: function (settingName) {
      if(this._settings[settingName])
      {              
        return this._settings[settingName];
      }
      return "Setting not found";
    }
  };
}();

heavy.setup({"icon":"myicon.png"});
alert(heavy.getSetting("icon"));
