In a function, the identifier arguments references a special attribute of the arguments object. You can obtain the parameter values passed to the function by number (rather than name.

In a function, the identifier arguments references a special attribute of the arguments object. You can obtain the parameter values passed to the function by number (rather than name.
For example, (used in prototype. js ):
The Code is as follows:
Function $ (){
Var elements = new Array ();
For (var I = 0; I <arguments. length; I ++ ){
Var element = arguments [I];
If (typeof element = 'string ')
Element = document. getElementById (element );
If (arguments. length = 1)
Return element;
Elements. push (element );
}
Return elements;
}
The Argument object also defines the callee attribute (no matter here ).
