Name
Function.caller — the function that called this one
Availability
JavaScript 1.0, JScript 2.0; deprecated by ECMAScript
Synopsis
function.caller
Description
In early versions of JavaScript, the caller
property of a Function object is a reference to the function that
invoked the current one. If the function was invoked from the top
level of a JavaScript program, caller is
null. This property may only be used from within
the function (i.e., the caller property is only
defined for a function while that function is executing).
Function.caller is not part of the ECMAScript
standard and is not required in conforming implementations. It should
not be used.
