Applies to: Function Object
The arguments property is used to get an array containing each argument passed to the currently executing function.
Syntax
function.arguments[ ]
The function argument is the name of the currently executing function.
Return
Returns an array containing each argument passed to the currently executing function.
Example
The arguments property allows a graceful way for functions to handle a variable number of arguments. The length property of the array contains the number of arguments passed to the function.
The following example illustrates the use of the arguments property:
function ArgTest()
{
var i, s, numargs = ArgTest.arguments.length;
s = numargs;
if (numargs < 2)
s += " argument was passed to ArgTest. It was ";
else
s += " arguments were passed to ArgTest. They were " ;
for (i = 0; i < numargs; i++)
{
s += ArgTest.arguments[i] + " ";
}
return(s);
}
document.write(ArgTest(2, "Hello", 3));
