javascript - Call function so this not needed -

i have application uses v8 javascript engine, , within add functions namespace objects execute lines of code database. contents of these functions need not have this added before every function call. following example code of problem

var obj = {}; obj.method = function(a) { return a; } obj.executor = function() { return method(5); } obj.executor() referenceerror: method not defined  var caller = function() { return method(5); } caller.call(obj) referenceerror: method not defined 

as can see, neither way allows me call method without first adding this. there way of executing function it's context set in such way this not need added?

edit

this did work in previous version of v8 engine, seems recent 1 not allowing now.

"the client's write rules strings loaded database, , requirement (who knows why) need write function names , application sorts out scoping."

if you're not running in strict mode, can use with statement.

var obj = {}; obj.method = function(a) { return a; }; obj.executor = function() {      (this) {         return method(5);     } }; obj.executor(); 

var caller = function() {      (this) {         return method(5);      } };  caller.call(obj); 

not saying great solution, it'll work if requirements given.

i don't know other requirements, can achieve via closure well.

var obj = {};  (function() {     var method = obj.method = function(a) { return a; };     obj.executor = function() {          return method(5);     }; }();  obj.executor();
