Returns a reference to the function that invoked the current function.
functionName.caller
The functionName object is the name of any executing function.
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.");
}
