I want to dynamically call a function from a string like User.find. A script would call the function find() in the object User if the function exists. Here's what I tried:

 var User = {};

 User.find = function(){

     return 1;

 }



 var input = 'User.find';

 var some_data_array = {name: 'John Doe'};

 var method = input.toString().split('.');

 var nameObj = method[0].substring(0,1).toUpperCase() + method[0].substring(1);

 var methodToCall = method[1];



 nameObj.call(methodToCall, some_data_array);

But it always returns:

 nameObj.call(methodToCall, some_data_array);

 TypeError: Object User has no method 'call'

Any idea? I can't use window since it is a node.js problem, the script is not executed in the browser.
