function

Required. The name of the currently executing Function object.

The length property of a function is initialized by the scripting engine to the number of arguments in the function's definition when an instance of the function is created.

What happens when a function is called with a number of arguments different from the value of its length property depends on the function.

The following example illustrates the use of the length property:

В	Copy Code
function argTest(a, b) : String { var s : String = "The argTest function expected " ; var expargs : int = argTest.length; s += expargs; if (expargs < 2) s += " argument."; else s += " arguments."; return(s); } // Display the function output. print(argTest(42,"Hello"));

The output of this program is:

В	Copy Code
The argTest function expected 2 arguments.
