Microsoft® JScript® caller Property |
Language Reference Version 2 |
Returns a reference to the function that invoked the current function.
functionname.caller
The caller property is only defined for a function while that function is executing. If the function is called from the top level of a JScript program, caller contains null.If the caller property is used in a string context, the result is the same as functionname.toString, that is, the decompiled text of the function is displayed.
The following example illustrates the use of the caller property:
function CallLevel() { if (CallLevel.caller == null) return("CallLevel was called from the top level."); else return("CallLevel was called by another function."); }
