This property held the arguments to the function. + * function f() { + * return f.arguments[0]; // deprecated + * } + * var x = f(3); // x will be 3 + * + * This feature is not a part of the final ECMA standard. Instead, scripts + * should simply use just "arguments": + * + * function f() { + * return arguments[0]; // okay + * } + * + * var x = f(3); // x will be 3 + * + * Again, this feature was motivated by performance concerns. Access to the + * arguments property is not threadsafe, which is of particular concern in + * server environments. Also, the compiler can generate better code for + * functions because it can tell when the arguments are being accessed only by + * name and avoid setting up the arguments object. + * + * Author: christine@netscape.com + * Date: 11 August 1998 + */ +var SECTION = "function-001.js"; +var VERSION = "JS1_4"; +var TITLE = "Accessing the arguments property of a function object"; +var BUGNUMBER="324455"; +startTest(); +writeHeaderToLog( SECTION + " "+ TITLE); + +new TestCase( + SECTION, + "return function.arguments", + "P", + TestFunction_2("P", "A","S","S")[0] +""); + + +new TestCase( + SECTION, + "return arguments", + "P", + TestFunction_1( "P", "A", "S", "S" )[0] +""); + +new TestCase( + SECTION, + "return arguments when function contains an arguments property", + "PASS", + TestFunction_3( "P", "A", "S", "S" ) +""); + +new TestCase( + SECTION, + "return function.arguments when function contains an arguments property", + "[object Arguments]", + TestFunction_4( "F", "A", "I", "L" ) +""); + +test(); + +function TestFunction_1( a, b, c, d, e ) { + return arguments; +} + +function TestFunction_2( a, b, c, d, e ) { + return TestFunction_2.arguments; +} + +function TestFunction_3( a, b, c, d, e ) { + var arguments = "PASS"; + return arguments; +} + +function TestFunction_4( a, b, c, d, e ) { + var arguments = "FAIL"; + return TestFunction_4.arguments; +} +
