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.
Description
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!'); }
Examples
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!'); }
Specifications
Not part of any standard. Implemented in JavaScript 1.1 and removed in bug 7224 due to potentially vulnerable for security.
