How to get the global object in JavaScript? -

I want to check in a script if another module is already full.

  If (ModuleName) {// extends this module}  

but if ModuleName is not present, then Throw s.

If I knew that global object I could use it

  if (window.ModuleName) {// expand this module }  

But since I want to work with both modules both browsers and nodes , rhino , etc., Code> window .

As I think, it does not work in ES 5 "Use Strict" ;

  var MyGLOBAL = (function () {this return;} ()); // MyGlobal becomes zero  

This will also fail with a thrown exception

  var MyGLOBAL = window || Global  

It looks like I have been left with

  try {// expanded module name} (ignore) {}  < / <> <>

 OK, you can type  typeof  , And if the identifier is not present in any location, then it  not   error , it is currently  "undefined" : 
 
  will come back if (typeof ModuleName! = 'Undefined') {// ...}  
 
 Also remember that on the global code  this  Science, refers to the global object, which means that if your  if  statement on the global context, you can simply  this.ModuleName . 
 
 About  (function () {this;};} ());  The technique, you are right, the  this  value will be just  undefined  on the strict mode. 
 
  
 
 
  
  
  
 
 
  Miscellaneous global = function ('return it') ();     
  Function  The constructor created with the constructor does not inherit the caller's strictness, only when he / she accepts 
 < P> This method is compatible with any ES3 implementation. 
 
 
 
 For example  indirect  eval  calls , 
 
  "Strict Use the"; Var get = eval; Var global = get ("this");   
 The above will work because in ES5, use  eval  as both indirect calls, variable environment and language Related Details

 But keep in mind that the final solution will not work on ES3 implementation, because the variables and lexical environments of caller on  eval  ES3 will be used as an environment for evil codes. 
 
 And finally, you can find out if hard mode is supported: 
 
  var isStrictSupported = (function () {"strict use"; return ! this;}) ();
