Question

I am being passed a string similar to below.

"Users_Controller.login"

“Users_Controller” represents the object below.
And “login” a method within it.

var Users_Controller = ( function () {
return{

  login : function(vo, callback)
   {......}

 }
 })();

Given only the string as a pointer,is it possible call the method?

You can use this function:

function getPropertyFromString(str, start) {
    str = str.split(".");
    var prop = start || window;
    for (var i = 0; i < str.length; i++) {
        if(prop == undefined)
          return prop;
        else
          prop = prop[str[i]];
    }
    return prop;
}
getPropertyFromString("Users_Controller.login");

However, this does not allow bracket syntax.
