Description
The arguments object is an array that contains the values that were passed as parameters to any
function. Each time a function is called in ActionScript, an arguments object is automatically
created for that function. A local variable,
arguments
, is also created and lets you refer to the
arguments object.
Property summary for the arguments object
arguments.callee
Availability
Flash Player 5.
Usage
arguments.callee :Function
Description
Property; refers to the function that is currently being called.
Example
You can use the
arguments.callee
property to make an anonymous function that is recursive, as
shown in the following example:
factorial = function (x:Number) {
if (x<=1) {
return 1;
} else {
return x*arguments.callee(x-1);
}
};
trace(factorial(3)); // output: 6
The following example is a named recursive function:
function factorial(x:Number):Number {
if (x<=1) {
return 1;
} else {
return x*factorial(x-1);
