Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The obsolete arguments.caller
property used to provide the function that invoked the currently executing function. This property has been removed and no longer works.
This property is not available anymore, but you can still use Function.caller
.
function whoCalled() { if (whoCalled.caller == null) console.log('I was called from the global scope.'); else console.log(whoCalled.caller + ' called me!'); }
The following code was used to check the value of arguments.caller
in a function, but doesn't work anymore.
function whoCalled() { if (arguments.caller == null) console.log('I was called from the global scope.'); else console.log(arguments.caller + ' called me!'); }
Not part of any standard. Implemented in JavaScript 1.1 and removed in bugĀ 7224 due to potentially vulnerable for security.
Supported nowhere. Historically supported in IE 3 till IE 9.
