Example
Function F1 ()

<Title> arguments. callee and function. caller </title>
</Head>
<Body>
<Script language = "javascript" type = "text/javascript">

Function F1 ()
{
Alert (arguments. callee); // The result is the same as that in the following sentence.
Alert (F1); // display the code of function F1
}
F1 ();
Function F2 ()
{
Alert (arguments. callee. caller); // The result is the same as that in the following sentence.
Alert (F2.caller); // If F3 is called, the code of function F3 is displayed.
Alert (F3); // display the code of function F3

Function F3 ()
