Comment déterminer ou récupérer le contexte d'execution en JS?

[Xenos]

Via "arguments.callee.caller":

var x = true;

var toto = function test()

{

	console.log(

		 "CONTEXT = ",		(arguments.callee.caller == null?	'global':	'local')

		,"This = ",		this

		,"x = ",		x

		,"arguments=",		arguments

		,"callee=",		arguments.callee

		,"caller=",		arguments.callee.caller

	);

};

toto();



(

	function()

	{

		var tatati = function test()

		{

			console.log(

		 "CONTEXT = ",		(arguments.callee.caller == null?	'global':	'local')

				,"This = ",		this

				,"x = ",		x

				,"arguments=",		arguments

				,"callee=",		arguments.callee

				,"caller=",		arguments.callee.caller

			);

		};

		tatati();

	}

)();

CONTEXT = global This = Window contexte.html x = true arguments= [] callee= test() caller= null
CONTEXT = local This = Window contexte.html x = true arguments= [] callee= test() caller= function()

A adapter si besoin.
